+1, I use and rotate in my twenty five+ year old Forte' Audio 3/1A (Pass Labs) Class A 50 watt stereo amplifier [Jon Soderberg upgraded last year].
Has a nice large transformer, Toshiba Mosfet output transistors. Four new power capacitors, and bridge rectifier's. True Class A, 50w@8ohm, 80w@4ohm. Sounds fantastic and competes with many expensive amplifiers today. Also have the matching Forte' Audio line stage preamplifier with dual pre-outs in stock form.
While I use my 6SN7 tube preamplifier with it, rotating my mono tube amps in/out, I've been playing this SS amp for the past year every other weekend. Liking it quite a bit. I might part with it to do the same upgrades with two of them as monos for my larger custom speakers just for fun. Not necessary, this stereo amp version is plenty on its own for speakers 90db+ efficiency. This amp keeps me from using my tube amps due to how it performs and sounds as a true Class Amplifier. Make sure you have a good tech who can check, upgrade, and freshen up your amp for you.
