On the plate of those valves there is going to be very high voltage.. you’re definitely going to need a dc blocking capacitor in series with the prob 👌
I have a driver transistor on a power amp that distorts the the sine wave signal into a sorta noisy stair step pyramid. I have changed all the caps. What could cause this. The following transistor driver is a lot worse. The output to the speaker Looks like its only amplifying the negative swing of the signal. Bad bias resistor? Bad transistor?

Good tutorial with a very important caution at the end.
I think you need a Blocking Cap maybe .1uf/600VDC to do this safley in ANY AMP.
You should probably add that this is for TUBE AMP troubleshooting and explain what could happen if you try this on a non-tube amp :)
quite a informative video 👍

My god. No
Show us how it’s done then !

He should a capacitor in line but otherwise nothing wrong with this method
@@Danilo8208SS a cap or a resistor?
