Complete re-cap and overhaul. The original tape guides and motor had long since been removed, so I used the 24V motor winding to make a nice pedal power supply, and modified the existing send/mix/feedback circuit within the amp to utilize a modern delay pedal.
The internal Danelectro delay is set full "wet," and the delay mix and repeats are controlled via the internal tube circuitry. The footswitch turns the delay off, just like the original amp, and for all intents and purposes the amp works like it did when it was brand new.
