Yorkville Bloc80b, service manual or schematics?

[J-bazz]

Hello everyone!

This is my first post here!

I recently picked up an old Yorkville Bloc80b and it didn't work when I got it. Opened it and I could see that one of the fuses after the transformer and there's also a cord loose that I can't really tell where it's suppose to go.

My plan is to recap it and give it some new life and a needed cleanup but I need a schematic or/and a service manual to continue my work. Does anyone have one?!

I believe this is the Traynor version http://traynoramps.com/downloads/servman/sm_ycv80.pdf. Traynor and Yorkville are the same people and you could write them here.

Thanks for fast replay!

There's no tubes in this one unfortunaly, this one is a quite simple transistor amp with 80W and a 15" speaker. I will send them an email, thanks!

Got it! Fast reply from the Canadians!

The schematic should be glued to the inside of the amp cabinet. My block40 does. The old Block 80 was identical except for a higher voltage transformer.

I didn't have one in mine, here's the schematics anyway. Also for Bloc40b and there's small changes on the scheme through the years.

Thanks for posting that service manual which I downloaded - might come in handy for my 80b.

Sorry for reviving such an old thread, but I recently picked a BLOC 80w (wedge, not watts), and was glad to find the schematic here. Just to contribute, attached is the (relatively sparse) owner's manual. At least it has real specs, all in one place.
