The gold band = 5% [IMG]
The resistor is RED RED WHITE. That's not a standard color code.
Put the amp back to stock. The schematic is here: https://drtube.com/schematics/marshall/jcm800pw.gif
You will need to adjust that resistor in Post # 233 above. The resistor will put you in correct range for EL34s. I'm not sure what that resistor...
Wait a second. You turn off the power FIRST? Then you switch the standby SECOND? That not the right way. No wonder. To turn the amp OFF: Turn...
Don't really know until I look at the schematic if there is one. What's the actual model number of the amp? Could be a design error, could be a...
i never classified Jeff Beck as belonging to any particular genre of styles. It's more like he invented his own.
You can ask VHT a question here: https://www.vhtamp.com/contact This is not what we usually see in a tube amp, but ask VHT about it.

Not really normal. What speakers are you using? Arcing can occur when there is a speaker problem / impedance mismatch.

The resistor looks like: Red Red White, this is not a standard resistor, the stock resistor for EL34 should be 27K Red Red Orange. So it's a...
So we need to figure out what that 1 resistor should be. Because right now it looks like the tube might be too hot and you can't adjust the bias...
You very nearly killed yourself and now have a second chance at life. He was initiated.
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy,...

Now all you need to do is get the bias voltage into the right area by changing the resistor.
I think you pass OK. What we would look for is a big jump not a tiny one.
