Nick,
>From the RCA Transmitting Tube Manual:
575A:
Mercury Vapro Rectifier
Fil: 5V -at- 10A
PIV: 15 KV
Max I Ave. 1.5A
IPeak: 6A
Peak Tube Voltage Drop: 10 Volts
Also, the 673 is similar to the 575A - is this what you have instead of
a 678?
I wasn't able to find any references for the 474A or 678. Good luck!
