Re: THR101 in the power supply

Thanks Darren,

1 Ohm was what I had thought, so confirmation is good. I'm still not sure about the power rating, but I'll go with 1/2 W.

I have uploaded a list of replacement parts for everything I can find - i.e. everything except the transformers and inductors. A couple of the diodes are no longer obtainable, but there will be modern replacements. All of the electrolytics are 105C and of a higher voltage rating than the originals. All except the mains side ones are low ESR.

I haven't yet decided how much I am going to replace. I have removed all capacitors and power resistors and found the base of C115 to be decidedly bulged. The rectifier diodes are probably past there best, so I may replace those too. I'll probably leave the feedback section alone as this won't have been stressed like the rest of the circuit.

Kevin
