Please note "electrostatic Speaker" (special handling req'd)

Yup! I buy it at HVAC wholesalers all the time. Highly recommended for electric motors.

Solder wick works ok but this thing is SOO much easier. the pins on the large relay are about a 16 guage. The header pins are about 14 guage wire and I was able to remove it without damage. The power cord on this model is complete garbage.

I found a cheap desoldering tool that works quite well. Most hardcore hobbyists have their favorite tools (plunger type suckers, complete $$ soldering-desoldering stations,etc) I found this one on amazon (no affiliation) I am not going to link to this one as the quality leaves something to...

Nylon center bolt or use some tubing around the edge of the cover to keep it insulated from the chassis

Search for a virtual center tap on the filament winding tied to to the 6l6 cathode circuit that might be floating or badly connected. This usually used as a lift to keep heater to cathode insulation happy.

Absolutely no need to parallel 2 6sn7 sections to drive an el34. switch to a 6j5 if you want to use 2 separate tubes.

SEND IT TO A FELLOW MEMBER FOR PROPER DISPOSAL!!!!!!!!!!!!!

something similar if you can, find the book https://ia802900.us.archive.org/27/items/GE_Essential_Characteristics/GE%20Essential%20Characteristics_text.pdf

These transformers will make about 2 watts ok singe ended if you want to try.

833,s running flat out will cook about anything

A 100 ohm 1 watt resistor across the output may save you some brown underwear in the future.

See tubelab.com. check out the SSE amp

Compensation caps. In.the feedback loop will vary with different transformers

The secret in the design is if the 274's short out you still have a rectifier. The 10 ohm resistors will still protect the sand from spikes. (snide comment)

check values of resistors r102 r103 in the power supply. (kind of hard to read the schematic)

Todays wall voltages tend to be higher. Your readings are not bad.

Mercury Magnetics can be $$$$$

Check the 3.9k resistor. All 2nd node voltages on the power supply are low

I have found some of the military output transformers available on epay have the frequency response of a telephone.....300 to 3khz Are your OPT's military surplus?

over large power indicator lite!

Thanks. Just trying to save some smoke.

Any one tried to use a toroidal transformer as a bucking traansformer?? I know they hate half wave rectification.

p-t31 transformer should work. 5k to 8 ohm on a 4 ohm speaker=2.5k primary. Great for a 50l6 at 120 volts on the plate.
