5F2-A Mercury Magnetics Power Transformer wiring

Post by lacrebob »

I'm trying to build my first amp - A 5F2-A clone.

I purchased a Mercury Magnetics FTPP-5 power transformer. I'm planning on copying the original schematic and layout. Compared with the original schematic and layout, the MM FTPP-5 power transformer has 1) an additional Green wire, 2) an additonal Red/Yellow wire, and 3) an additional Green/Black wire.

Here is my best guess as to how I should deal with these:

1) Extra green wire goes to the pilot light along with the other green wire.
2) Green/Black wire is a center tap wire for the 6.3V filament - ground this wire.
3) Red/Yellow is a B+ center tap - ground this wire.

Is this correct?

Twist the two green filament wires together and attach them to the 6.3V pilot light.

The other two go to ground.
