I was wondering where you were with that amp! Sounds great to me. How are you liking it?

I really like the sound of it with the MXR DynaComp. It's one of the Custom shop reissues.
And Slaving, Holy Cow... It's killer Dude!

killer tone. Can you go over the specs of the amp one more time, I lost track after 48 pages.

Thanks.

[vkaxeman]

Thank you. My 68 is modded the same way except for the filtering on the screens and mains. Can you explain how to change the screens and mains filters to 16 and 32 uf.

[Omn]

And
and
what will changing from 68/2.7K to 68/820 at V1b
and 68/1K to 68/820 at V2a do for sound?

[Cabbagebreeze]

welcome man! and thanks for that. you will see there are many here that have a grip on the 12 series tone and have posted some killer clips.
there are some different ideas on how to achieve evh.
from my experience ill give you good starting point.

check list to evh:

330u/820 - .68u/820 split cathode
.0022u bright channel coupling cap
330u/820 v2a
33k/500p tone stack - 500p on the bright channel mix resistor
.1u in the phase inverter ( output coupling caps)
47k feedback resistor on the speaker tap ( 16 ohm feedback )

dual 16u preamp
32u PI cap
16u screens
50u mains

with everything on ten this is a real good start in evoking the dutch treat

Mark

Please excuse my laziness is not re-reading the 48 pages, but is the above spec still the evh 12000 series standard?

[theonea ndonly]

Hy Mark,
just to be shure ...

is

Phase Inverter Input cap .022
Output Coupling caps .1

your 12xxx -Spec?

Only because that is usually the other way arround.

thank you
Joerg
