Hi Mark,

A new desktop 6V6 push pull amplifier will be available in next month. The dimension is same as this 6L6 amp. It should better match with Alpair 10 and Alpair 12 as the output power is 12W.

Cheers,
Tony.

The size of this 6L6 amp is compact. We try to make this kind of single end tube amplifiers as small as possible. It can match style and sound with CHR-70, CHP-70, Alpair 6 nad Alpair 7.
