My pristine Yamaha A-1 is back home again, and worth the wait!
Glenn performed a check-up, recapped the power supply, replaced the relay and various other items, including some unruly diodes...even some LEDs where the lamps used to be.
I know that I rave about the Yamaha B-2 amp and its VFET outputs, but I don't know what Yamaha did with the design of this A-1 amp it sounds just wonderful...again--crystalline and powerful. No more pops, either!
Now, it's time to restore my accompanying ADS L910s--when I heard a pair of these with an A-1 in 1978 it was a splendid experience!
Thank you Glenn!
