I have a fault on my Decca 5501 LF transmitter. It appears that the
main output transformer / combiner is faulty. Each Tx module takes
current when connected to the transformer, even when the output is
disconnected. And there is no power out of the transformer.
I have some questions:
According to the the circuit diagram, the transformer's output
winding has a 3.3nF capacitor across it. However, it seems to be
invisible! Does anyone know where it is? Is it inside the pot core?
Does anyone have a spare transformer for sale?
Has anyone had a similar fault?
Is it difficult to disassemble the transformer?
It is very difficult to test for shorted turns because the resistance
is extremely low.
Any ideas?
