Hi All, I’m finishing up a Mills Dance Master, I have it all mechanically working and I’m now ready to work on the amp (an MCP 1644 amp). I have a schematic for it from the manual but it is not very useful because the caps and resistors are only marked with the mills ‘mcp’ catalog number and not with the actual values. The corresponding parts list has the same issue with just listing the Mills catalog numbers and not actual values. I checked with Bill Bickers at Jukebox friday night but he does not have a schematic with values or a rebuilt kit either. If anyone has a schematic or a listing of the caps and the resistors and choke for this amp please let me know. Thank you for your help.
You may have to visually inspect the unit and manually match the components to the schematic. Depending on how much it's been disturbed over the years, this could be a chore.
Early resistors used a body-end-dot scheme with the same colors used for banded resistors. The body is the first significant digit, the end the second, and a dot in the middle the multiplier.
Capacitors had various color code schemes, there are some like dominoes and some black with multiple bands. Google and a multimeter with capacitance are your friends.
