they always pulled out and serviced the receiver and record player, rarely ever replacing caps back then unless it was an RCA "firecracker", usually just a lube-a-trol on the pots and FM alignment touch-up. That was my part of the job which really was a team effort because I always went along to pick them UP 
Our local PA-dutchy sounding folks who loved their console stereos and lighter early American furniture were S-O-L when it came to replacing them in the 1980's. No more theatres were made and nobody made a furniture grade cabinet like RCA and others used to
This was done at least a dozen times while I was there after HS in 1981, then 1984-87 while at PSU's branch campus studying physics and electrical engineering. These gut-outs provided me with many projects because I took EVERYTHING left behind, including what was usually a replacement CRT. One of the first conversions the old fella there did was to this very model
and I made myself a fantastic color TV using a cabinet from a beautiful teak Scandinavian cabinet vacated by an unfortunate CTC17X chassis which had a cooked flyback 
no loss, only improvement. That lasted trouble free all summer in my first apartment, then I had to sell it to buy books from the infamous and onerous PSU bookstore. DGMS (dont get me started) I was missing those awesome controls with power tuning and individually lit channel numbers.
