Title: Silvertone 1432 / Tremelo Problem
Post by: plexi50 on May 13, 2011, 02:14:15 pm

Hey all! I have an old 1432 Silvertone and the Tremelo is not working. I have traced to a yellow wire from the EQ connector plug socket and up to the grids of the 6V6 power tubes. Then i have gone over to the two .01 caps which i think are the trem caps for speed and presence. The Intensity pot show voltage. The Speed pot is not functional. I can find no schematic anywhere but i think im close to figuring it out  :w2:.  Any ideas are welcome  :help:

Tubes are (1) 12AX7 - (1) 6AU6 - (2) 6V6 - (1) 5X4

Maybe try the 1482 schematic.  It uses the same trem tube.
