Atma-Sphere MA-1.5 Mono Block Tube Power Amplifier Pair

These rare and beautiful amplifiers are in outstanding condition with no functional issues. These are truly a work of art... not for the beginner - but extremely rewarding sound quality and aesthetic beauty as well. These have been meticulously cared for by the previous owner who used them in a complicated 6-way crossover network to drive one pair of midrange drivers on a highly modified set of Legacy speakers.

The tubes are all in good condition - each has 4 Jan-Philips 12AT7 and 4 RU-6C33CB Russian Military tubes (these are great!). Previous owner recommended that this amp warm up for 15-20 minutes prior to use and be re-biased regularly if you are not using daily.

Cosmetic condition of the amps is exceptional. From 3 feet away, they look brand new. If you examine very carefully, you can find some very light, very small scratches in the chrome. Overall appearance is truly excellent. See photos for details.

Amplifiers are rated for 117v or 230v operation. Serial number on each amp says 169
