Fairly desirable model if you want more than an A/B/C/D with tonewheel reliablity. Schematics are online. Diving board keys, not a problem to me but I don't play with my elbows. To sound like new need dozens of electrolytic caps. TG caps are film. Vib & perc controlled by tabs, can be flicked with one finger from keyboard, traditionalists find it objectionable doing that without dedicating a hand to the job. Percussion requires modification to get twos and threes, and slow fast. Tube amps-mostly don't need tubes, except 5AR4 rectifier, still in production in Europe. Pedal is monophonic, although if your really wanted the upper octave again softer on the lower octave like an A/B/C/D, the modification looks possible. Requires a modern run cap and power cord quickly to prevent fire/shock.
Often go for $500 here and southeast, in mostly working condition. Smooth talkers can get them for free, however. Is one on CL today. from a reseller for $500
