Howdy,
I'm finishing up a new build loosely based on an 18 Watt Superlite TMB w/ss rectifiers, and thought I'd take some thermal camera readings of the board, tubes, and transformers.
Turns out the 1 watt 220K bleed resistor generates more heat than I'd expected, and the 10 watt 240 Ohm sag resistor gets quite hot - enough so I think I'll up the wattage rating on these two parts.
You might find the attached photos of interest.
Cheers,
Greg
