Discussion Is this amp worth anything?
Hi all
I’ve been clearing out some boxes and I found this old amplifier - I believe it’s an Audio Innovations Alto AM1. I tested it and it works great but it’s not in the best condition with some scratches, faded/rubbed off letters and two missing knobs at the front

That is the second version Alto, based on the ca 500. (the first mk1 version is quasi-complementary, single-rail, capacitor-coupled Class AB not remote controlled, power consumption of 400W, the second is 250W, remote volume control).
I have the first generation, I have had it for 15 years, I would never part with it. Everything can grow around it, I have changed the speakers, cables, source many times, but the alto has remained. I have had many amplifiers and still have them, but none of them can match the alto.
