Just bought off ebay because it was my first brand new audio purchase back in high school. I loved that amp but it got away from me, I was looking for years to replace it, found one that was built the same day I was born 8/10 (what are the odds?!?) I stupidly hooked it up to the Martin Logans keeping the volume low. Amazing MOSFET sound from this little 50watt amp! I had a cassette deck on top of it, checking frequently to feel if it was getting hot, it was getting quite warm (there was no other way to set the amp and a source with my custom speaker cables). It suddenly shuts down. Into protection I assume. I unplug it, there was no magic smoke, nothing smelled burnt, I let it cool down overnight. Next day I push the power button, the lights come on, the meters salute, the button doesn't stay engaged, the lights go back out, I opened her up, nothing looks amiss. I took some crappy pics. #3 and #5 show the power switch area, there is a small brown wire going from the bottom of the switch to the main board, it has 'mute' stamped on top of the board where the wire wraps around a post. I have little to no tech skills. I'd appreciate any and all input on areas to look for the trouble spot. The fuse is intact, it's hard to see in pic #1 under the bundle of wires.
Thanks in advance, SM's for this amp must be like hen's teeth.

    Craig I bought and still have an A35. Somewhere in the basement in its origional box. I bought the schematic diagram when I bought the amp. I can scan and email it to you. Or send it by post. During the 28 years I've owned mine only the "on" switch and one channel power transister has failed. I had them both replaced by a pro. One of the best sounding amps for the money. Email me at mtwphl@yahoo.com

    Hello to all. First of all congratulations to all about this energetic and enthousiastic community. I would appreciate if you send me the Sanyo's A35 schematics to jpaudiolab@hotmail.com. This amp is a very good one for its size and age.
    Thanks in advance.

    Hi,
    Just wanted to update and let all who have been looking for the schematic diagram for the Sanyo A35 Plus Series integrated amp that this link is still alive. I respond to the email address above. I have had quite a few requests over the past few years. And have replied to all of them. Also I have submitted the diagram to "HiFi Engine" so you can also find it there. Also I have brought the old stereo components up from the basement and started using them again. Wish I had done it a long time ago. Happy listening . . .
