Perreaux 5570

lazenna · 25th March 2011, 03:18 AM

Hi guys I picked up a Perreaux 5570 that I want to restore. Wondering if anyone might have the schematic to the 5570. Also anyone with similar Perreaux's suggest any upgrades to this amp.Thx.

I would email Perreaux, they really seem to be quite helpful. These are great amps if they are similar to the 5550 which I suspect they are.
Ive had several Perreaux amps, but never upgraded them. I expect some of the film caps are average and electrolytics are due for a refresh. At this sort of voltage (100V)there aren't too many audio cap options.

Thx Luke yes I think they are almost identical. As part of the restoration I will probably contact Perreaux also.

by the short form data sheets about
High End Audio Amplifiers for Audiophiles : Support : Product Archive - Perreaux (International)
is mentioned at botton, if schematic diagram and product manual is available or not.

Unfortunately no schematics were converted in pdf files for download.

I want to have a schematic overview from all models of this brand.

BTW - the first devices was the GS2002 (GS-2002), an integrated amp.

Hey guys I just picked up this Perreaux PMF-5550 amp and it has a dc-offset problem with the left channel, and a buzzing in both channels. I figured I could switch out the smaller electrlytic caps and the to-39 and to-92 transistors. Problem is I cant figure out wat the transistors are, I dont have the service manual. From what I can find on the net is that the to-92's could possibly be MPSA92's the to-39 have writing on them STi 8532 ST-4154. I belive the to-39's are made by STi but cant find any info, I was wondering if I could use the 2N5154 to-39's I would be very gratful for some help thanks
