Hi Both, It was a case of brain freeze yesterday.
MrBill, After discussing things with you, I now understand the relay is activated by the foot switch ( not for the oscillations ) of the circuit.
This is why my concerns were about a relay for oscillations because of the noise lol.
So you are saying it works on the principle of a transformer ratio and then a regulator?
You are correct in saying everything is inside the ( sealed black box ).
When I condemned the unit there were oscillating noises but no output voltage. It was extremely low.
