Note: If your power transformer has a center tap for the green heater wires and you replace it with a non center tapped power transformer,
You will have to add two 1/2 watt 100 ohm resistors to the heater circuit to make an artificial center tap.
This page will explain how to do that.

Note: To determine if you have version a or version B TBPT, use a multi meter set to continuity.
You will get a beep from the Orange wire to the Brown or Black wires on version a.

Note: The last batch of TBPT's that I received from victoria amps has the orange wire moved to the other primary.
I think the transformer guy just got the two primaries mixed up but it will not matter since both primaries are equal.
I made a new diagram above and instructions below for wiring this version B model as I am calling it.
Nothing is different except that the orange wire has been moved.
