I just finished the restoration of a pair of KLH Model 23's and thought I would share a few pictures and the wiring diagram for others since I could not find it on the web anywhere. I hate to say it but they sold to the first guy that called me. Anything that could have been done was performed except I did not replace the resistors on the crossover. The paint I used was ACE Premium Enamel, Chocolate Brown in a satin finish. Just thought I would mention that I do not recommend taking the pot's apart for a thorough cleaning since they are very difficult to re-assemble but it can be done.
