After I found it, I used this as a power amp for several years. I found
that, with the tone controls bypassed, if you use the "output to tape
recorder" jacks as inputs, you are bypassing all of the preamp stages in
this amp and you get the clearest sound. This is borne out in the SCA-35
schematic you can find linked on this page:

Until I got a much much more expensive amplifier, I preferred the sound of
this amplifier over everything else I ever heard.

Have fun bidding!
