  1. I haven’t listened to a 3B but it’s big brothers have been very impressive. Bryston bass is just fantastic, fast and powerful. Also rich in the all important mid bass. I have not found the big brothers thin, definitely not etched, with plenty of detail. It appears as the generations have progressed they have become better with each model, smoother, more detailed, blacker backgrounds with ever decreasing noise floors and distortion. To my knowledge they should run 3B, 3BST, 3BSST, 3BSST2, 3B3. If available at a fair price I would grab it. Partner with a nice valve preamp and enjoy.
  2. Almarrow a318B. 18 Watts of 6C33C and one stunning looking piece of kit. They were sold in Melbourne by Audiophile so should be some floating around the suburbs. Don’t seem to hit the second hand market very often which is a good sign. Lovely thing that you can hot rod if that is your fancy. Were crazy cheap for what they are. However, if you can find a used pair, Audion Silver Nights. PSE or push pull 300B Monoblocks. Fast, weighty,and seemless top to bottom. Magnificent vocals. 18 Watts is like a different dimension compared to 8.
  3. To me “fast” refers to the speed of “acceleration” and “braking”. By which I mean there is no delay in the rise time or beginning of a note, rhythmic or percussive event , nor bloat or overhang at the completion of the event. In other words correct timing. It is amazing how slow some amplifiers can sound when compared to a truly fast amp. Recently comparing a Bryston 14BSST (600 Watts) to a more modern Bryston 4B3 I was shocked how much faster the lower powered 4B3 was. The 14BSST was not an amplifier I would have ever called slow but it sounded rhythmically deficient in direct comparison. In speaker terms something like Klipsch Corner Horns can make most other speakers sound slow with percussive sounds like a snare drum or clapping. By the same token in other areas they can sound a little thin and shouty. Finding that perfect balance of a fat and speed is what I think so many of us chase.
  4. Room twelve oh two. Sounds like the title of a tawdry thriller. Given the pre realease photos however , it might actually be a very tawdry “adult” movie. (not the ones of Hugo however!)
  5. Well it has been awhile. Bought a Bryston 4B3. Brilliant.The level of detail was beyond anything I have heard. AudioNote M5 to Bryston to Ambience, incredible. Bass that made a Yamaha B2 sound deficient and a 14BSST slow. Detail to make a valve junky sit up and take notice and simply explosive dynamics. Way better than I had even hoped was possible. Then I took down the walls.....should sound better right? Well no, it sucked harder than a turbo charged Dyson. Spent forever building absorption, hanging panels, moving things around circles. Just sounded worse. Sold the 4B3 to that Evil C Clive. Much sadness, just stopped listening. Finally got properly crazy. Bought the speakers 2.8 meters off the back wall and plugged them into the 2 Ohm tap on the Audions. You little beauty! Very, very good. Not quite what it was but dam fine. Even better if you want you can sit behind the speakers and it sounds the same! Now I just need to work out how to make the rest of the house work with the hifi in the middle of the living room.
  6. Hi Aussievintage. Are you in a car ( like a Falcon Wagon) or an SUV like a Territory? If you are running what I would call standard tyres with a recommended inflation of 32 psi or similar I would still come down to about 28psi on the gravel. It will improve your ride and decrease your punctures. I would certainly come down on the van, those tarmac pressures will really cause it to bounce and skip sideways. If you have a dirt road close to home take a Sunday drive with the van on and try these lower pressures. Chances are you will be very happy with the improved ride. I understand that this can sound strange ,especially when the owners manual recommends increased pressures. Good advice on the sealed roads but not the dirt. Investing in a little 12v tyre compressor can remove all the angst as you can adjust pressures as you experiment and come up to road pressures when you depart the gravel.
  7. This definitely complicates matters. Most 4wd tyres tend to be 75’s. The skinnies 80’s and lower profile 70’s. Chances are yours will be 65 or even 60 profile. This gives you far less side wall to play with. As Glen says the trouble here is if you come down too far you risk rim damage as you lack the cushion to absorb higher impacts. I think we can be sure you will have alloy rims which fracture unlike steels which bend so you can loose the tyre and rim with a decent impact. Given the fact you are running 18” rims the tyre will also be biased for road use so likely less ply, softer rubber and less tread depth. All of these factors increase your puncture likelihood. A final thing to be aware of is that the more remote you get the smaller the range of sizes available. You will pick up anything for a 16” at Mt Dare but not an 18”. Stories of week long waits for rubber to fit X5’s have kept the locals in cheap laughs for decades. Loose 10 to 15% of pressure and see how the tyre looks. Does it start to ‘bulge’ slightly? Run it up the track a way. Can you feel impacts coming past the tyre and into the rim, like an under inflated tyre on a bike. What you are looking for is a slight bulge on the side wall with lower impact shock. Go too far and impact shock will increase again as the side wall bottoms out. This is dangerous and will result in sidewall and possible rim failure. Number one rule, reduced speed will result in reduced punctures. However on corregated roads finding the right speed to suit the frequency of the surface is more important. Going slow can result in just smashing the tyre,rim,suspension into each rut.
  8. They will need to come down too. Being a light truck tyre, chances are they are running more ply than your vehicle. Chances are they also have more and harder rubber on them. This is a definite advantage. However, you need to have a think about weights and level of impact. How much does your van weigh? Light truck tyres and high pressures are used to deal with weight, as opposed to grip. (generalisation of course) Your van hops about more than your car. It tends to ‘bounce’ the full weight is also placed on a single axle rather than shared by two. A huge thing to remember is that a flat, and especially a slow leak ,is far less noticeable and picked up later on a van than on the vehicle. This is why you often see trailer / van tyres completely shredded and destroyed. The great risk in this is that a blow out results in fish tailing and in the worst case a flipped van and/or a rolled vehicle. Finally when heading bush people may carry a second car spare they often forget an extra for the van/trailer. Personally I would be getting them down to about 35psi on the dirt and seeing how they respond. Monitor the tyre temp in comparison to the car, just use your hand. The lower psi should decrease the hop and bounce, thus reducing impact pressures. Just as a flat tennis ball bounces less than a fully inflated new one. Again keep the best tyre on the passenger side as these get the worst beating. Finally if you still use a ball hitch I can not recommend a Treg hitch highly enough.
  9. All I can say is do not believe those who feel high pressures reduce punctures. I am good friends with Lyle who has run the Marree roadhouse / general store for 40+ years. I spent a lot of time with Adam Plate, who ran the pink roadhouse with his wife Lynnie at Oodnadatta for 40 years. These people opened up the outback and between them would have repaired and replaced tens of thousands of tyres in the Outback. Adam wrote countless advisory notices on tyre pressures and remote travel . Both of these men with daily exposure to every tyre , vehicle , load and used pressures will tell anyone who will listen to keep their pressures at or under 30 psi on gravel and to engage 4wd on all gravel surfaces. The problem is this feels counter intuitive to most people who have spent their lives hearing about the blow out / over heating problems caused by under inflation on tarmac. Remember the underlying heat of black tarmac on a hot day is very different to gravel. Also keep in mind these pressures are only slightly below what most cars run in daily use. It is very wise advice to fit new tyres prior to a long trip. With worn tyres the chance of piercing the carcass increases dramatically because there is simply far less rubber to penetrate on the blocks of the tread. What might make a gouge on a new tyre now passes right on through. It also puts the thinner rubber between the tread blocks much closer to the road surface resulting in far more pressure at the point of contact with a sharp object. A smaller sharp object will result in a puncture.
  10. No worries mate. Flat tyres suck, even worse with a trailer getting in the way of the wind down spare!
  11. Hi Full Range, It used to be one style for all but now they have increased the options. For every day use and abuse the Terra Trac 2 is the one you want. What sets them apart is they share a lot of traits with light truck tyres and their side walls are incredibly strong. You will see in their designation after the circumference it says LT which is a light truck designation. He may be offered the choice of Canadian made or Chinese made, I found no discernible difference between them. He may also be offered differing ply levels, just grab the most on offer, I think most are 10 ply but I think there used to be a 12 ply. The Terra Trac TG Max appears to be even more hard core but was not available when I was using lots of tyres. If not insanely more expensive it may be worth investigating, it seems to have been developed for mining and forestry. Unfortunately prices may may not be as low as was once the case due to wheeling and dealing in the US market. I would be interested to see what is quoted now. I used to pay about $210 fitted and balanced for a 235\75\16. That is probably about six years back. Looking online that figure is now probably closer to $250 but still not expensive in 4wd terms.
  12. More than fair gentlemen. It is a strange device this internet. It can cause reactions that are out of all proportion to the subject being discussed. It can also cause people ( like me!) to take offence where none was intended. I was not aware that Hercules and Cooper were in bed together. Hercules are always hard to source in Cities, almost like Coopers hide the brand. I can not understand why Coopers with their huge brand recognition would not market them under their own name for use in the purposes I have illustrated. They retail for far ,far less than the Coopers branded products. Any how, thank you both for extending the Olive branch, I will make sure to be less reactionary next time.
  13. Around the 80kph mark, depending on the roads condition. Freshly graded, especially clay topped major tracks will easily accomadate these speeds. The major tracks today are like highways compared to what they used to be. Of course these speeds will drop with deteriorating road surfaces. Over corrugated surfaces it is simply a matter of finding the correct frequency. Often a faster pace will be far less detrimental to tyres and vehicles. At around 28 to 30 psi you will not overheat the side wall. I have never had a heat fatigue related blow out. As you know over Summer it is often in the mid to high 40’s through central SA and the NT. On an extremely hot day a departure inflation of 28 psi can easily rise 4 psi. Of course once off the major tracks speed can drop to crawling pace and pressures in the worst conditions to single digit numbers. The vast majority of bogged vehicles fail to get through due to over inflated tyres. 90% of punctures on gravel, especially harsh gravel ,are caused by over inflation. The tyre is like a ping pong ball and any sharp object will pierce or cut the casing. Once pressures are dropped those same items are ‘cupped’ by the tyre and no longer penetrate the casing. I am guessing your brother in laws bussiness was up on Port Rd not all that far from Grand Junction? I notice it disappeared a few years back. Did he get out of the game? He always gave me a well serviced reliable vehicle. Heading Bush also got sold, no one does the deep dessert stuff anymore. I convinced them to convert to Hercules when I came from Camp Wild. Nothing could cope with the sheer weight of that Akarna on the rear axle except for the Terra Tracs.
  14. Look a Cooper on the Troopy, then again they all are aren’t they. Those are Yokohama’s on the Triton.
