Do you have the assembly manual?...

If the power transformer is blowing... I must admit I don't have a schematic
to follow.. can you disconnect the load from the power supply and see if the
transformer gets warm... my rational is that the output capacitors might be
leaking excessively and may need to be replaced...

I had a battery charger that frequently blew the bridge rectifiers until I
removed the output capacitor.. after that the bridge ran quite cool...
comparatively speaking...

I have been tinkering with a Heath SB 610 Monitor Scope with the
apparently fairly common problem of a Blown Power Transformer.
I read somewhere of people using an "outboard" transformer to work
around this problem. So, which winding is it that blows: the 215 VAC
or the 600 VAC. And can one just disconnect the blown winding and
connect the additional transformer at the appropriate point? Thanks
for any info.
