Continuing from STEP 3
Well, following up on earlier step 3 I de-soldered the transformer from the power amp board (safely isolated the secondary wiring because it could be LIVE)
... and guess what? The fuse still burns out.
What does that tell me? It tells me there is a short in transformer. There must be a short in either the primary or secondary coils.
The transformer is an ILP Type No 4UR36, batch no. 46240. ILP don't appear to stock it anymore, an Australian electronics distributor had some detail on the spec (link now apparently defunct) as follows...
Part No. 4UR36. 120 VA (Two Secondaries 60 VA per Secondary)
Secondary = dual winding
Output Volts for input of:
220V 230V 240V
34.43 36.00 37.57
RMS Current Per Winding: 1.67
