V2 pins 1, 2, and 3 are a dc coupled cathode follower. Those voltages are normal. I shoulda looked at the schematic. Some tubes are not up to the task with the 56K cathode resistor. Try a different 12AX7 or a 12AT7 to see if that stage is choking off the gain. Another thing to try is just wire the ...

Volume is at 3 in the room it's as loud as the drum set.

Isn't V2 a cold clipper ? V2 1 2 3 4 9 187 108 108 0 0 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 ...

Express, not Rocket, at least in all video I’ve screened.

..

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.

So there's no heaters.

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. 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 r...

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.

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.

The screen is 263 the anode on 6-7 is 254 4-5 is 278

I got it running but it is clean and not breaking up.

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

The HTS-9144 arrived today and can't find the schematic online. I'm assuming from memory that I'm using the yellows that are 250v to 5 and 7 and put 4007's to 4 and 6 and that i should tuck the yellow green into the bell cap. Grays to 2 and 8. the browns to power tubes. Please forgive me in the summ...

Triode delivered the a-470-s It was packed very well. Heyboer replied and is sending an invoice with a 6 week time frame.

Triode say's it's shipped due on Monday. Emailed a second time to Hey. Saved number to call on Monday unless they might be there today (Saturday)

I sent an email to heyboer and got no response. I'm not finding results on triode do they not ship or ship wrong item?
