I sure wish you had posted some pix of the front of the organ. The design of that vintage of Baldwin was spectacular in engineering terms. Very simple yet produced great sound. Check the keys. They may have been the rolling variable resistor type that made the whole organ "Touch-sensitive" - the harder you pushed the key the louder it sounded. The 6SN7's were used in divider chains to generate all the pitches from 11 master oscillators. Are there pedals in your model? I cry to think of cannibalizing such historic goodies. Were there two manuals or just one (sets of keys)? Where was it that you saw so many old electronic organs so cheap? -Dick (organ guru for over 60 years)
