  1. Hi Joh1975, I know it is a while since you posted but I just became the owner of a 4000A. It's not what you would call one of Pioneer's finest but it sounds quite nice. I got it as a give away from a friend but he kept the turntable so I got the receiver and speakers. When I finally got it connected and fired up, it sounded terrible but I new what the problem was. The speakers!!! I can only describe them as rubbish. I hooked up some old Wharfedale Denton's as I had 2 pair of these and boy did it come to life. I noticed from your pics that you have a copy of the owner manual. It's something that my friend informs me went missing many years ago. If there is any chance of getting a scanned copy of yours, I'd be happy to reimburse you. Cheers.
  2. Hi, I know I'm a bit late in replying but only just came across your post. I hope that you still have the Super 12's and those cabinets. Gilbert Briggs would have been pleased. They should go down low so if that's not happening then I suggest you get a specialist in driver repairs to look at them. It sounds to me (after having a lot of Wharfy's rebuilt) that the cones are not moving freely and therefore no bottom end. Iv'e had Super 12's (both Alnico and Ceramic magnet types) running in 4.5 cubic foot enclosures and they go nice and low so your cabinets, which I'm guessing are getting up around 7.0 cubic foot are more than ample. I have a pair of Celestion G18C 18" bass drivers (the hifi versions) in 6.5 cubic foot enclosures and they go so low so cabinet size for you is not an issue. Super 12's were one of the best full range drivers that Wharfedale ever built in their heyday although they can benefit in the upper registers with the addition of a Super 3 tweeter in the same cabinet but isolated from the Super 12. Stick with them, get them refurbished and you won't be sorry. I can put you on to a Wharfedale specialist in Melbourne if you still have them. Just reply with your email address. By the way, a good 20 watt/channel amp is all you need with these as they are very efficient. Cheers.
  3. Hi Mat-with-one-t. I know it's a while since my original posting but I had a PC crash last year and once I got it up and running again I had no idea that I wasn't being informed of any postings. I have since found out a bit more about the OS turntable and that it is a bit of a rarity. I was going to use the original arm and then thought I'd use a Grace arm that I have packed away but I would prefer to stay with an arm of the era and I recently purchase an Acos HGP39 (also known as the "black shadow") which is in great condition. It's the speakers that got me interested. Your's are a copy of the original Wharfedale "Column 8" which used the model 8/145, 8" full range driver. the were installed in a black cloth sock to minimise the amount of dust settling on the driver. Unfortunately, when the drivers died or became faulty, people would just rip them out, throw the socks away and fit Super 8's which looked the same and most likely sounded pretty much the same. I have a genuine pair imported from the UK in the early 60's. I found them on a guy's veranda 2 years ago and they look like they were ready for the tip. He insisted on taking only $40.00 for them which I agreed to immediately and when I got them home, the drivers had been replaced with some cheap Pioneer drivers. They have now been fully restored and have rebuilt Super 8's in them. They don't go very low but they do sound nice. By the way on the originals, the top section (approx. 4" high) is removable so that you can access the driver easily. Refer to the attached pics. You'll notice a similar one in the background. These were made in Brisbane in 1962 but I recently moved them on to pay for other projects. Originals or not, if I were you, I would not be letting them go any time soon. Cheers, Andre
  4. I'm having a similar problem trying to find the user manual for an SR82. Apart from the service manual, which is easy to find, I can't find anything except a lot of dead ends. Seriously frustrating. Even the Marantz download site doesn't have a record of it. Age should not be a reason for deleting it from that.
  5. Yes, I also found that on HFE but that's all it is, a service manual. Thanks again for your help. Will keep hunting. Cheers.
  6. Thanks Ozcall. It worked perfectly. Don't suppose you have the manual or are you just familiar with these units?
  7. Hi all, I recently came into possession of a Marantz SR82 (74SR82/07B) Receiver. While it is a Dolby pro-logic surround sound receiver, I will actually use it on my workbench in stereo mode for testing rebuilt speaker systems as I had sold the amplifier previously used in this capacity. It seemed ideal at the time because I needed dual speaker outs, it came with a functioning remote, was made in Japan and it only cost $50.00. Problem is that while it works and I can get it to run as an amplifier only, it has a clock built into the display that I an unable to set as I didn't get the owner manual with the unit. This clock display sits there blinking at me regardless of whether the unit is switched on or not. Programming the tuner presets also appears to require a degree in sequential button pressing. Surely there must have been more than one of these things sold in Australia and there must be an owner manual floating around. If anyone wants to admit to owning one of these and the said manual, I'd be happy to pay for a hard copy or PDF in order to stop my misery!
  8. Hi Dan, I know this was a long time coming, but as they say, better late than never. The SQ101 along with a couple of other models was their early attempt at moving from valve amplifiers to solid state types via the germanium transistor route. While a lot of people poo-poo germanium based amplifiers, I have found that this early path to solid state by Luxman sounded better than their initial follow ups into silicon transistors. They (IMHO) just sound nicer. I am about to become the owner of a 101 and fortunately it has not been "got at" although it also has one broken speaker terminal. In those days Luxman just couldn't make up their minds as to what type of termination they wanted to use and almost every new series of that era had different speaker terminals. I have 2 Luxman SQ77T/II amplifiers and their terminals are also incompatible with any thing else on the market. By the way, if you look at the innards of your 101, you'll notice that it is almost identical to the 77. They even appear to use the same power transformer. I have the owner manual for the 77 in PDF and if you still own the 101 it might come in handy although the 101 has a slightly different control setup. The 101 looks a bit like a 77 in a bigger box. By the way, these early solid state Luxmans will definitely increase in value, even though they are not super high powered so if you've still got it, keep it! The 77's sound fantastic with older efficient speakers and I reckon the 101 will too. Cheers, Andre
  9. Hi all, I have just become the happy owner of an Orpheus Silex turntable (made in Melbourne, Australia in the 1960's). I understand from what I have read that it was popular at radio stations being used as a transcription unit and is built like the proverbial tank but also has a cult following in the vinyl fraternity. I've been told that it still runs so that's good but I gather that it will probably need a re-build. It also has an arm on the dodgy plinth (also to be replaced) that I would like to know more about. My question to anybody that is up to speed with these is, who/what were "Orpheus Sound Reproduction Equipment" in Melbourne Australia? The attached photo is all I have at present but will upload more when I get it.
  10. Hi Anthony, Have come in seriously late (like 9 years) but I have just acquired an Orpheus Silex with a mystery arm. I'm picking it up tomorrow and ....... it was a gift from a friend! I'm looking forward to checking it out and doing a resto although this one is mounted in a dodgy plinth and is also missing the arm bracket. When finished, I'll build a new plinth and mount an arm straight to that as the idea of the arm support bracket does not appeal. I'm also curious as to how you went with HiFi Exchange as that business changed hands two or three years ago and has moved a couple of times. I don't visit their site much anymore because they list a bunch of stuff and then have "sold" on a lot of it. I really don't want to see the sold stuff, just the stuff that is for sale and from what I've seen when I once visited the shop, they just seem too lazy to list everything that they have. At the time I visited the store they would have been listing only about a third of their stock. Also a significant number of items just were not even for sale. Sorry, just venting a bit. From what I read in your post, they should have swapped the turntables at their cost. Seemed like a little bit of interesting advertising to me or did they just send the wrong one? Anyway, I hope that you have kept the turntable is I consider it to be a significant part of the history of HiFi in Australia. Cheers.
  11. I know its a bit late in coming but I only just saw this posting. Magnavox 8WR's were marketed as a budget enthusiasts full range speaker with impedances of either 8 or 15 ohms and a maximum power handling of 10 watts RMS. They were manufactured in Sydney from the mid 1960's to early 1970's. They were also a direct competitor for the very popular Rola C8MX which was manufactured in Melbourne but they never got anywhere near as popular. A lot of their production went into OEM products for Australian manufacturers of radios, stereograms and television sets but even in that area Rola were in the lead as they had a much larger range of speakers to accommodate just about any type of equipment. The 8WR's had ALNICO magnets while the C8MX's had CERAMIC magnets which were officially rated at the same power handling as the 8WR's. I have a pair of both in excellent original condition and while the C8MX would always win the "shootouts", I find that, in non technical terms, the 8WR just sounds a bit nicer. Both have pressed metal baskets with paper cones and surrounds although the wizzer cone in the C8MX is noticeably bigger than the one in the 8WR. The magnet housing on the 8WR was usually red but could also be blue. Guess it was a case of what paint they could get at the right price! The ideal enclosure recommended for these speakers was a 2 cubic ft. vented enclosure. If you still have them, keep them. They aren't worth a fortune and good examples will now only bring around $20 to $30, but they are an important piece of Australian manufacturing (and in particular electronics) history. I wont be letting mine go any time soon. Cheers.
