here is the story, bought a AC4TV off Ebay for $100. Started playing it and started to smell something.. could be dust, kind of a plastic getting hot smell.. but wanted to make sure. I had the amp open as I did not want to turn it on until I check that everything looked good after shipping. I played and it sounds good.. fun amp, but still smelled something..
I watched the tubes and the EL84 glowed more than any EL84 I have seen. Looked like a 6L6 in a fender champ.
I have a video, I used my phone, sideways to the tube with the cathode to the left and you can see the tip light up with the heater. As I play, the cathode brightens with audio. after a min the anode starts to light up.
This happens even at low volume.
The cathode cap and resister are reading correctly.
I am thinking of adding a screen resistor, say 1.2K 1 watt.
I appreciate any help, Thanks
