I had a gs35b amp with a 20 watt glitch resistor. I can't remember the resistance 15 or 20 ohms I think. Ive had a tube short and pop the 20a fuses immediately. The same tube actually did it twice. After cooking it for a couple of days the tube is still good. Ameritron does the same thing.

RESISTOR, METAL OXIDE FLAMEPROOF, 470K OHM, 2 WATT. Commonly used in the high voltage power supplies of many Fender&lifiers. RESISTOR, METAL OXIDE FLAMEPROOF, 100K OHM, 1 WATT. Two of these are commonly used as balancing resistors across the main filter capacitors in higher power Fender&Silverface Amps.(pipe) Resistors Types And Applications Nuts & Volts Magazine(steel) High-voltage resistors must be kept clean. Fingerprints, oil, dirt, and dust all create unwanted current paths, lowering R P and increasing leakage or even arcing. This is why resistors for use in high-voltage circuits are long and thin with their terminals far apart to minimize leakage and maximize the ability to withstand high voltage.(pipe) Should I replace these resistors on my vintage radio High Voltage Resistors and Resistor Kits for Tube Radios (steel) Put a 1watt or even 2watt resistor in place of that one. You would also do well to replace the resistor(s) which feed voltage to the screen grid of the AF output valve. Even if the screen grid is fed by voltage divider resistors which have gone high in value by equal amounts, I suggest replace to be prudent.

First, there are no suitable microcircuits directly designed for work with high voltage.

There are many ways of reducing the plate voltage on valve equipment .I have done this on radios but not on a guitar amp .The most common way I hav High Voltage Resistors and Resistor Kits for Tube Radios Best answer 4You can lower the voltage by adding a huge 40V Z-Diode into your B+ supply. Obviously these diodes will disipate a lot of heat and need a heat-sink.2there probably isn't a whole log of current going through those things. If so, put some bulbs, or even LEDs in there.1Honestly, I would leave things just as they are. One benefit of higher supply voltage is more output power before clipping occurs.

Tube-era capacitor analyzers - Part Two; Knight, Eico High Voltage Resistors and Resistor Kits for Tube Radios

High voltage and leakage tests Like the 950A, the Eico 950B uses a high voltage supply of about 720 volts with two electrolytics in series. If its 68K resistor has drifted high, the tuning eye will see voltage higher than 200 relative to chassis and the test voltage (the high B-) will see that equivalent amount subtracted from 520.(pipe) TubeSound Blog Archive Capacitor Tester repair-calibration(steel) This ~720 volts will be divided between the magic eye tube and the voltage-divider string.
