Guest jakeyb77 Posted June 17, 2018 Share Posted June 17, 2018 So I opened the new ME850 today. Thought I’d see how it’s faired over the years. Foam everywhere. It’s all perished and the fan is free floating. I wanted to get it serviced anyway so off we go. Link to comment Share on other sites More sharing options...
ray4410 Posted June 17, 2018 Share Posted June 17, 2018 i feel your pain jake,had my 750 done 6 months ago by ron over at winovate ,done a great job,that is the only drawback with later model ME amps the bloody foam rot a bit like JBLs with foam surrounds you know at somtime you will have to replace them.

As you said gotta be done sometime. At least gives me a chance to get it back to spec as well. Link to comment Share on other sites More sharing options...
lusk Posted June 17, 2018 Share Posted June 17, 2018 Awesome amp the 850, wish l never sold mine. Is that free floating fan legit? l'm sure l've seen that brand before from china. Link to comment Share on other sites More sharing options...
Guest jakeyb77 Posted June 17, 2018 Share Posted June 17, 2018 Yeah the fan sits inside a foam block as per below. As to which fan it should be I’ll leave that up to @PonyTail or @Zaphod Beeblebrox to answer. Anyway I cleaned out all the perished foam. Otherwise the amp runs like a dream.

ray4410 Posted June 18, 2018 Share Posted June 18, 2018 don't run it too long without the foam in place jake as you are probably aware that the fan is focused on the heatsinks to keep the trannies at a constant temperature,without the foam the air is all over the place.

Not running it at all. I’ve left it off the rack. Messaged Ron to see what his schedule looks like. Link to comment Share on other sites More sharing options...

Darren69 Posted June 18, 2018 Share Posted June 18, 2018 @Zaphod Beeblebrox kindly lent me a ME pre some years back and have always remembered its gorgeous sound. If I were to build a killer ME system for my crap rock recordings, what would it be? @Jakeyb77 love your mono's & JBL set up mate, would love to hear that one day.

The problem when using ME amps with poor quality recordings is well known. The computer adage: GIGO (Garbage In - Garbage Out) applies. ME amps (and preamps) are designed to be ruthlessly accurate. I would advise you to think carefully. You may be better to look for an amplifier that can disguise the faults in such recordings. ME amps, generally, will not fit that purpose. However, the best ME power amp was the ME1400 mono. Sadly, they are almost impossible to find. I doubt there are more than one or two pairs on the planet. Maybe none, as several were re-manufactured into stereo amps. Fortunately, a standard ME1400/1500 amp is very close in sound quality and both amps are relatively plentiful. Be advised that the ME1400/1500 requires the very best loudspeakers to be used. Paired, obviously, with an ME preamp, you will have a system of serious capability. What speakers would you be using?

As with others if you ever want to pop over. going to run the monos with the 4435 when I get them. Slowly gathering all the parts. They are 96db sensitivity so wont be an issue I expect. Haha.

Amps- am sad. All gone. I don't know the ML5, but if it has been developed by using very low output impedance amplifiers (ie: NOT valve amps), then the ME1400/1500 may be a good match. In general terms, the ME1400/1500 works very well with speaker systems employing large, heavy bass drivers. That said, I have a couple of clients using ME1500 amps with speaker systems employing 130mm bass drivers and the amps perform very well indeed. What do you mean by: "Amps- am sad.

OK thanks for the advice Trev. Was alluding to your comment re- all the 1400 monos being gone. However, if the standard is close then good-o. Mikes speakers are a low load apparently (am not an electrical type person, sorry). Link to comment Share on other sites More sharing options...

Had someone here on Sunday hence the reason why the 1.7 was back on line! He brought his NAD375 that’s supposed to have the capability to drive 2 ohms.... Can never make out NADs specs but I believe it was a 150W/4 or 8 ohms whatever that means.... haven’t had the 1.7 on for st least 18 mths and I thought it was a but tinny in the SQ dept. any how this member enjoyed his music and made some comments. B4 we rapped it up I said you need to listened to what the Magtech does. I couldnt remember in my head what it would be like because I haven’t had the rig on for most of this year! The Sanders Electronics ajust took the SQ to another level! Then we put the diy ribbons with 2 Eton drivers/channel Listening to a few tracks we played before and then I get the comment: “ I’m really now spoiled”. I can just imagine what it’ll be like with an ME 1500/1400, 850 in the house. Now who said electronics didn’t make a difference?

Art Vandelay Posted June 19, 2018 Share Posted June 19, 2018 (edited) @georgehifi might chime in later today with a report on his 850 when he puts it back together. Resistor upgrade DC servo cap upgrade & another modification that George will comment on. Edited June 20, 2018 by Art Vandelay 4 Link to comment Share on other sites More sharing options...

gat474 Posted June 19, 2018 Share Posted June 19, 2018 No worries @Jakeyb77. If you do decide to sell them or your 850 be sure to think of me first. I still rue the day I decided not to buy the 300’s and then I backed it up by passing the Adelaide 850 to a local sale a few months ago! Once I’m serious and financial again I’ll do something about an 850. Link to comment Share on other sites More sharing options...

There's not much between the ME1400 Monos and the regular ME1400/1500 (which are internally mono anyway). Don't forget: The ME1400/1500 was fitted with a split wound (one winding for each channel), 5,500VA, double C core power transformer. The only possibility of crosstalk was when demand approached the 5.5kVA mark. By that time, you would have lots more things to worry about (like blown fuses and circuit breakers). That said, I thought you had some nice mono amps? Link to comment Share on other sites More sharing options...
