I have a trade in Art Audio Concerto 6550 based stereo power amplifier for sale. It looks very good and sounds excellent. We rated 7/10 but as you can see in the photos some would say 8/10.  It is a push pull triode amp that makes 40 watts with 6550 or KT88.Li comes with the 6550 tubes as shown. It also uses 12AX7 small signal tubes.

Output transformers were custom-designed by Art Audio. The MK2 that followed this was a $5000.00 amp. This came out at $2795.00
