Greetings Group,

Does anyone have any info on an old mono Lafayette RK-137a Recorder?
Solid state Rectifier but one 9 pin socket and two 7 pin. My best
guess is 12ax7/12at7 --- 2X 6aq5. Does anyone know for sure?

Thanks much,

Tony WA6LZH



Yes, I know this is 10 years old, but during the two week "holiday season" I'm
going through the 'treasures' in the basement, and I have an RK-137A, and its
manual. Tubes are

12AX7 to left of volume control
12AU7 behind tone control
6AQ5 behind 12AU7
