Thanks Damen!
I had sams 394, showing the HF 1290 series HiFi's but that had a separate amp chassis with P-P 6L6
, which is not much like mine as it has 410 V as highest B+
After I replaced the 120 ohm, both 40 uf electros, and powering up at only 70 volts, it still smoked the R60c section, even after I disconnected the 20uf caps.
These resistors are always trouble, this one probably has a fault in the middle section to ground. A high impedance fault as the waxed-cardboard insulator likely tracked. Some DC appears on the other taps, so its NOT a low resistance short.
