Thanks, it's a very nice amp but restoring it wasn't a lot of fun. I'm glad I went through the exercise but I wouldn't want to do it again anytime soon.Wow, that's a nice piece of equipment. I bet it's loud and sounds good. And I love the lit volume knob
My main goal was to improve long term reliability since the SA-9900 probably has more of the known troublesome transistors than any other Pioneer product from that period. Among the parts replaced, I found several iffy caps and one open emitter resistor. The amp sounded very good beforehand and I'd say that after restoration, it seems to have more authority in the bass region as well as a little more detail at the top end.

Those are impressive looking speakers. What brand and model speakers are on the ends with the two huge woofers? Are they 10" or 12" or what size are they?
What other equipment you have connected to your gorgeous amp?
Speakers and a phono cartridge are a good place to spend a fair percentage of your audio budget, they will reward you with excellent sound.
The SA-9900 is part of my bedroom system that includes the following:
TX-9500II Tuner
CT-F1000 Cassette deck
SG-9500 Eq
PL-530 Turntable
Chromecast Audio
Allison Four speakers + SVS sub
