I was extremely skeptical about this-
I understand most of this skeptisism. But if you think about it; conductors and magnetic fields are worst enemies in a amp.
Glad you noticed any difference. When you get it at bandvolume the difference is even bigger.

No Erwin  you are a star for pointing this out to us all with pics as well.
I spoke to Nik about it and he is aware of it too.

This I believe is the secret ingredient as well as ensuring your cathode and anode (plate) wires are parallel .  This is the dumble special lead dress and it works.

It made such a difference with the OD trimmer set at 26K to ground (middle lug and outer lug) Right if you are looking at the black side

This is 9 oclock on some trimmers and 11 oclock on mine. My trimmer reads 85K overall.

This is important as I have unleashed tones I didn't think the amp was capable of.

I was thinking of selling it but did all the similar mods to Jack but used RN65's for both anode and cathode resisters. I now have the tone in my head.  TAD 6L6 WGC short bottles are ace by the way.

Erwin.....Your are a star....it makes alot of difference ...I am very grateful to you

regards

Richard

Too much honour Smiley Enjoy that big fat massive tone now...
Look at Dumble pictures and Fender filament wiring. They were the smart guys.
However I hope Ceriatone is gonna change there method of filament wiring.
Floating from one tube to another is the way to go in building the d-style amp IMHO.

Hi Richard,

Anyway thnx!
It' s de-mystifiying the lead-dress thing.
Dumbles and Trainwrecks( as I heard) are the most unstable amps when it comes to wiring.
You're spot on right with the cathode and plate wires, ceriatone is already doing a good job there!

Grtz Erwin

Hi-

A question for Erwin- I have an HRM, from 2009.  is the implementation of the lead dress changes the same as in a non-HRM?  Does Nik do the changes stock now?

Thanks

Yes HRM is the same n lead dress. I don't know if Ceriatone has changed it. Better ask Nik.
