My Dad provided parts from a solid state Lowrey and Hammond, and Ron Ashcroft provided the AO-35 from a Hammond. Friday I retrieved a 1961 Conn model 541 "Minuet" in non-working order. This was listed in the free section of CL. Yes it is a tube job. The amplifier is actually a stereo power amp using two pairs of 7868. These amps go through two crossovers to drive two 15" speakers and a rotating assembly with a Jensen driver. I am thinking about removing this entire assembly complete. The photos show that each key is controlled by half of an 12AU7 and its own tunable transformer.
