Looking for a Rotel RX-154A (Or similar) schematic

wildswan · 14th September 2009, 03:35 PM

I'm looking for a Rotel RX-154A schematic in order to fix an amp that belongs to a friend of mine. It has 4 channels, and seems to be a quasi-complementary design with 2sc1061 transistors.

It has sentimental value so I'd love to get it fixed. I think the output transistors may have bit the dust, but it's very dirty inside so I really need a schematic to do it safely!

Thanks in advance

Great site, unfortunatly nothing similar there! Thanks for that.

Would anyone have any Rotel schematic with a quasi output stage?
Or know of an amp with a similar output stage (2 TO220 NPN devices per channel)

I'm finding it hard to find anything useful to go by

I had good luck e-mailing to Rotel tech support, it can be found on their main site.
They e-mailed me back a pdf version of their service manual of the amp I was interested in.

Good luck, Peter
