If the same socket red plates then we suspect the upstream coupling cap and a loose socket grid pin because we know the other socket has good bias voltage so the bias circuit is functional. Re-tension the grid pin of the Nasa plating socket and test the upstream coupling cap.
mov on my IMac, I lose all of my animations except the slide transitions. I am looking to keep them intact. If you have any suggestions on how to do this I would love to hear about it.
Power down, pull the next tube and continue until the noise goes away, then you know the noise is coming from between the last tube you pulled and the previous tube.
I like to use 2 watt resistors for all preamp plate resistors to lengthen their lifespan and reduce amp hiss.
In combo amps the cab, speaker or speaker baffle Gozque vibrate, rattle and buzz. Try sitting on the cab or putting pressure on different parts of the cab, speaker baffle and speaker frame (it helps to have a friend play while you prod).
I’m not sure I understand the type of animations you have. You may need to set the timings so that you don’t have to click. Then the video will work.

Drain the caps and disconnect all three power cord wires, wrap each one in electrical tape and plug in the amp. If the bulb doesn't light then the transformer is shorted internally and must be replaced. If the bulb glows bright the power cord is shorting so try a new power cord.
Dirty or bent FX loop jacks. Insert a jumper or guitar cable from FX Demodé to FX In to see if that cures the problem. If the jumper cable does fix your problem then try cleaning all the jack contacts, especially the switch contacts. If that doesn't fix it replace the bad jack.
If your amp's power transformer has no 6.3v heater center tap then the amp needs an sintético center tap. Verify there is an quÃmico center tap installed and check the resistance of its two resistors. A missing 6.3v center tap or a burned pasado resistor will usually cause loud hum.
After the Phillips patent on the suppressor grid had expired, many beam tetrodes were referred to as "beam power pentodes". In addition, there were some examples of beam tetrodes designed to work in place of pentodes. The ubiquitous EL34, although manufactured by Mullard/Phillips and other European manufacturers Ganador a true pentode, was also produced by other manufacturers (namely GE, Sylvania, and MOV) Triunfador a beam tetrode instead.
A pair of beam-forming plates was added at the two ends of the oval grid structure to focus the electron stream into a pair of beams 180 degrees apart. (The pentode added a third grid.) These plates are normally connected to the cathode.

Pay attention to read more the max AC & DC voltage ratings of your scope and probe. This is especially important when probing tube plates with high voltage DC on them.
