Default accuphase e202

I just rescued an accuphase e202 .The guy was going to sell it as scrap metal. I really didnt know its value I gave him 20 $ Every review is an A+. It wont power up. I replaced all 3 fuses reset does not seem to have triggered. There is one blown lamp fuse I made a few calls and no one had the 8 volt .3 . I have a 7.25 volt lamp in its place . I read a post that if the lamp goes the unit wont power up? I do not hear a click from the relay next to the power switch. The board behind where the 3 fuses are looks overheated. I can feel heat there. I found a post showing that board and a description parts replaced http://www.praudio.co.uk/repair%20summary10.htm . I am looking for someone that can repair this locally Chicago or I can ship it 50 pounds.

A friend just paid $600 CAD for one to use as a pre-amp... even as just a power supply & chassis, it is wrth many times the price you paid.

$20 for an Accuphase E202. I can't even call it a steal... I just paid $600 for mine. Once you have it fixed you will be flying.

Hi Glen27,
I can let you have 2 replacement meter lamps.
Thought that was the problem when I bought my (now fixed) E202.
Bought a few when I eventually found a source!
Definately worth pursuing repair, quite a wonderful amp :-)
Email me your address, if you need them, and I'll get them to you next week.

Alistair

Thanks I have 2 packs of 6.3 volt lamps. Hopefully those are ok.
I had it working for 5 minuites then dead.
No lamp power no relay click.
The relay engages with the power board in.
When I install the amp boards no relay.
There is something that isnt on those boards that needs to be replaced. I have at least $ 100 in parts including spares.
Its time to pull the face plate and start probing the other boards.

Hi Glen,
6.3 V is good.
I have a schematic (somewhere) that I could let you have, if it would help.

Hi again,

My E202 cut out on plugin to mains. Some cards showed what looked like scorching... NOT the problem!.... only due to long term use. Some E202's have modified AC input on the front underside, looks suspect, but only due to modification, so don't be mislead.
My repair cost 17 .... ca. 20 dollar U.S.!
Problem lay in bridge rectifiers on loudspeaker output.

Hi again,

The last photo on the first page is of the part I described as being modified. Remained untouched by me or my repair guy!

I didn't do the repair myself, I was told that the problem lay with the bridge rectifiers. This was put to me as though this was a frequent kind of fault.

As the repair was ridiculously cheap, I am sure it didn't involve high value components!

I'll try to find out more.

Good luck, and keep posting on your progress :-)
