'73 Silverface Super Reverb... that's a sweet amp.
You betcha..I love it, best sounding amp I've ever played, with the possible exception of a 70's Peavey Butcher that belonged to a friend, I played it many times onstage with his band for around 3 years.
Affordable? That's debatable...I was surprised when I started checking out retail prices on these things. I've always leaned toward pawn shop amps, you can get lots better prices on amps and guitars that usually need nothing more than a decent setup or much neglected maintenance.
When I got the Super, i started looking around just to see what it might be worth. I got it for 3 hours working on a relative's computer, fixing the first copy of the Sasser worm that I know of. (McAffee discovered it 8AM Saturday, she called me 6PM Friday night...) She gav3e me the amp, in need of repair, for fixing the computer. First one I found at a guitar shop was $1200...There's a Traynor 60 watt tube amp sitting in a local pawn shop now (or 3-4 weeks ago anyway), for just under $400...I've seen a dozen Peavey Classic 30's for $200-250, a couple of Classic 50's about the same. (I passed on a Classic 30 for $150, not enough bass gor me, now I know I could have just swapped out one capacitor and had a great amp)...Blackface, look for them to start at over $1500...and that's for a beat up one. My Silverface is in great condition, been sitting in a closet with a naugahide cover on it for 20 years, well taken care of before that.
Here's a pic of it, sitting behind my recently modified tele copy. I put a Peavey pickup in the neck position and swapped the white pickguard for a black one. my 74 Champ is on top.
I got a deal for sure, 3 hours work...same for the Champ really, $8 at a Houston flea market, $4 for some tubes down the hall, $12 for a Radio Shack 8" speaker, later replaced with a Gorilla 8 incher for a dollar at a yard sale...I've spent less on the Champ than you would spend for the tubes to retube it...The Peavey MX cost me $60, then $120 for repairs to get it working. More recently another $120 for a replacement transformer, and $140 total for the '67 Kustom 2x12 cab it sits on top of, so both the Champ and MX cost less than half what the Super Reverb goes for...Got my Peavey Classic 212 for $150 in a New Braunfels pawn shop, add that to the mix and it's still barely over half the price of a '70's Super Reverb or Twin.
Affordable though? I'm not sure I'd say that...Even the CBS Silverface amps are getting some pretty steep prices these days. They weren't well liked by musicians, which is the #1 reason Marshall became so popular, mainly due to the two issues I mentioned earlier, too much bass and loss of the high end chimey sounds, but they are now still considered vintage amps, and that means higher prices. No way I could afford to go out and buy one...
