Bought mine new in 1981 and it's been in use since then. Aside from the occasional pot cleaning, it has performed flawlessly since then. Most impressed and just love it. Plenty of power to drive my Klipsch's to insane sound levels.

Excellent amp!....Sounds great, lots of power.



re: SU-V4A

I recently found this amp in a recycling thrift store for 50€, it's replacing my Yamaha AX-496 for the moment.

Excellent amp indeed!
You should pay attention to the 2 power supply elcos, which can smoke and die. Really happened in 2012!
Kind regards
