Dahlquist DQ-20i crossover schematic

Does any one have a Dahlquist DQ-20i crossover schematic and maybe even a part list they would share? Hand drawn and scanned would be fine.

Suggested crossover upgrades would be great too.


     Check with these guys:


      Not really certain how disposed they are to helping DIY types, however.
My DQ-20s live again. Thanks for the schematic, Rich
