Newbe here, making a first post, bumping a thread about an amp I own.
I've had my SA-510 since 1988 or so, purchased for $10 at a garage sale. I fixed a problem in the input selection switch myself, and it has been very reliable ever since. I run it with a pair of Cerwin-Vega D-1s I've had for 20 years (need refoaming, but that's another thread), most often with the digital cable TV box as the input, and at low power (10W tops by the meter).
Crooner, I was wondering why you guessed they were 30W per channel; the back panel says 80W and the meter on the front matches that.
Retro, the front panel is 3.5" by 16.5" by my measurement.
I'm missing one of the switch covers off the front panel; no real problem but it'd look sharper if I could find one. I swapped over the subsonic filter switch to the one that was missing because I keep it on all the time. Also, I was wondering which tuner to keep an eye out for to match with it; there was no TX-510 model but I saw a TX-610 on the 'net this past week that looked interesting. One more question: the serial number starts with "BI" so this dates it to 1982 I think; were these some of the last of the US silver Pioneers?
Picture of the missing switch taken with flash (its in a dark corner of the room) so there's odd reflections in the face:
