I recall that and did NOT comment. That was before I got a small and middle version of your large "VCR series" 3-channel with living stereo AM-FM. I paid $75 for the larger one, 30 for the smaller. Both are dirty but complete.
Have you worked on yours? I have not, but am looking forward to working on my three tube RCA consoles as we go into dark season

One of mine has the reverb amp and it appears this one might, under the stereo balance knob..
Your amp has a three PP channels

while both mine use and RS189c three channel singe ended chassis.
Bill, That looks like a steal , how far is it from you?
