a Peavey Classic 120/120? They are the 2 long cement types. I wanna' convert back to 6l6's from EL34's, but I can't find my schematic/layout.

I don't have the schematic here for that amp, but they should be 100 ohm 5 watt resistors. I think every Peavey amp I've ever seen uses that value with 6L6 power tubes. There should be 4 of them, 4 - 6L6 power tubes right? If you go to the Peavey forum and ask Roger he'll tell you for sure.

For this application, I think that there is only 2. They are 10w1k's in there now for the EL34's. The're in the middle of the pic. I did go to the Peavey Forums, and some guy said that the original screen resistors are 100 ohm 5 watt. And if this amp was run with EL34s he would hope someone upped them to 1k 5 watt, and if they did I could leave them that way. Why would I want a different spec than what was original?  |

OK, I read this wrong. The screen grid resistors are what I was referring to. There's 8 of them in that amp. They are the smaller cement box resistors. The standard value of those is 100 ohm 5 watt. If those were changed to 1K you could leave them.
The screen dropping resistor is what you're referring to. I don't know what belongs in that amp because I don't have the schematic here. Peavey will email you the schematic is you call them. Many of the Peavey amps use a 400 ohm 10 watt resistor there but I don't know what goes in your amp. Sorry!

Okay. I looked in the amp, and yes, there is 8-100 ohm 5 watt's in there. So the 2 large cements are the screen supply? I found my old repiept from when I had it converted back to 6l6's the 1st time. It's hard to tell, but I think it says 2-470 ohm 10 watt resistors. Does this sound right?  |

The best thing to do would be contact Peavey for a schematic of the amp. That way you can be sure of the value. Many Peavey amps I've seen use a 400 ohm 10 watt resistor in that spot but I can't swear that is the value for your amp.
