Title: Doug -- wiring diagram of old transformer?
Post by: Mook on April 27, 2015, 02:05:53 pm

So, I bought this Power Tranny from you about 10 years ago.    I believe it's for a tweed deluxe.

I don't know the wiring layout.    Can you help?


It has:

Green, G/Y, and Green -- These are for the 6.3V filaments.

Red, R/Y, and Red -- Secondary Power, with center tap.

Black, Black/Red, and Black/White ---  I know they are primary, but I dunno what the voltages are......120v?  240v?       Do you know?

Last, it has:    Yellow, Yellow/White, and White --  I know somewhere these are 5V for filaments for tube recto, but what layout?


Here are pics:
