Output Transformer Primary Connections
With the filaments installed – lets now install the output
transformer wires – these are the primaries – the RED wire
as shown will connect to pin 2 of the 300B.
Then take the other black wire from the output transformer
primary and stretch it the other way across the chassis –
we are going to connect it to the Power supply.
Connect the black wire from the O/P transformer into the
Power supply at the same point where the black wire is
connected that is coming from the CHOKE – this is on the
second 15K resistor.
