Re: Rocket build
You are awesome sir. I ended up watching Uncle Doug and the wires were,
Gray 5 ohms,
brown 5 CT 00.5,
yellow/green 37.4 CT 18.4,
yellow 42.1,
Black 01.6

Re: Rocket build
I got it running but it is clean and not breaking up.
Re: Rocket build
The Rocket is a pretty clean amp as designed. How is the volume? Have you made all of your voltage measurements and written them down on the voltage chart? If so, post that here.
Re: Rocket build
The screen is 263 the anode on 6-7 is 254 4-5 is 278

I had rumble that turned out to be one of the 12ax7's.
Red plating changed 100 ohm 5w screen resistor to 470 5w solved it.

Re: Rocket build
It is very loud and clean. when crank it it only slightly breaks up. In the video I'm using a Maxon overdrive. Watching Glen Kuykendall and it's just screaming.
Even with the Maxon overdrive i can still hear 30% clean from the amp.

Re: Rocket build
The volume is like 10 but starting at 1. there is no chill between 0 and 1. at 1-2 sounds like 5 on my jcm900-100w but really clean.
Re: Rocket build
So there's no heaters.

Re: Rocket build
Although the rocket is warmer it still screams to a degree which this isn't and because the heaters have no volts i suspect that's why.

Isn't V2 a cold clipper ?

Those Voltages don't seem right. Maybe the 10K from pin 3 to ground is wrong or missing. Maybe a short 2 to 3 and no 10K ?
FYI: AC Voltages should read zero on a meter set to DC Volts.

Was reading rob robinette what to measure on ac or dc with tubes out and picked up on a few things today.

Re: Rocket build
Volume is at 3 in the room it's as loud as the drum set.
