Another Leak Stereo 20

Another thing you could do is measure between either end of the 12K resistor and ground. One end should read 100R and the other should be nigh on zero. Do let us know.

Measure across the 100R resistor, do you get 100R?. If so then there is a break somewhere in the loop. It could be open circuit in the transformer secondary but very unlikely. More like a ground wire is broken or left off somewhere.

Measuring 106.1R across the 100R resistor.

R18 LH from one end to ground measuring 97.3R other end as you say measuring nigh on zero.
R18 RH from one end to ground measuring 11.85K other end zero.

Well that's wrong. Should be 100R one way any nigh on zero the other. Looks like you have two missing connections as at least should read the 12K.

Going by your picture, you have two small 100R resistors. There should be 0 ohms between the left hand ends of those.

Hi @toprepairman when you are talking about thr 100R resistor are you talking about R21 or the 12K resistors at R18 one of which is reading 100R in situ or R4. I think we may be talking at cross purposes.

Cheers
