For anyone who might need spare parts and such, I have a RCA RT-21
transport with the associated transistor electronics and speed control.
The microphone preamp transformers are missing in the electronics and
the transport sustained some damage during transport. If you are
interested in part or all, let me know. It looks like the transport has
plenty of still-good parts that could be scavenged. Ping off list. If
no answer by this coming Friday, to the dump it goes.
