There's a full dissection of some of his amps and every single detail has been listed in detail. Interestingly enough, when it was analyzed, the changes Dumble made were not anything really earth shattering.
For example, @syscokid made changes to the voicing of my Origin 50 by altering capacitor values and adding zener diodes. It's not as complex as Mr. Dumble would hope to have you believe.
I bet @Ivanh could give you a really clear and concise rundown of what the Dumble circuit entails.

Lmao please tell me this a clever joke? Like im waiting for the film crew to pop out of the bushes and someone yelling that i " Got Punked!!"
Its a damn amplifier, not blueprints from the Groom Lake, NV Skunkworks Program! Might as well send these with secret decoder rings and some fezes lol

What ever you think Robert if you don't have a great clean sound ?? And #094 was owned by Gergor Hilden and Gregor was kind enough
to give me the details on his amp so I could build one then Gregor sold the amp a got a real 1959 burst gut shot Gregor sent me.
OP
Doesn't matter to me. The point is, there's no secret to Dumbledore's "secret mods."
OP
Nice phrasing on that track...
OP
I have a musical friend who is a Dumbledore aficionado here in L.A. and he owns two of them. He seriously considered buying #094, but it had been tampered with/modified and he waved off. I rang him up tonight and we chatted about the subject.
Amp #094 is a 1983 model. Gregor acquired the amp from a collector in Japan around 1992. Markus - a collector from Germany - bought the amp from Gregor in November of 2008, not long after it appeared in July of 2008 on E-Bay, item/listing number 140246482623.
In that listing, there were a number of gut shots posted publicly and they can all be found on Pinterest. There are no 'secret' photos of this amp.
From the gut shots posted allegedly by Gregor in the July 2008 E-bay listing, the following was observed:
1) Resistors hanging off the 40/100 switch but No indicator LED???
2) Where is the PAB relay???
3) No network on Send/Return
4) Can cap is probably 20uf x2 rather than 10ufx2
5) First PS caps 200uf rather than 300uf.
6) 6L6 screens and grids like #124 (5.1k and 470r)
7) To me it looks like 100k Metal Film plate resistors x4
8 ) PI plates 110k and 110k?
9) Slope 150k Carbon Film
10) NFB resistor starts with a "4" (470?)
11) no cap across V1b grid resistor.
For such a highly revered amplifier, it certainly changes hands often...

True I build a copy of #094 in 2008 next was ODS #183 EL34 100 watt my friend at Two Rock send me a custom wound power transformer
and I used a output transformer from a 1968 Marshall Super Lead sounds better than the real one I changed the filter supply to 1966 Marshall
JTM45/100 then the Green Hornet was born 50 watt KT77 1968 Marshall transformers and my preamp design not a copy of any amp
I learned from Dumble I went my own way.

Going one's own way is often the best!

Yup! A lot of L.A. based musicians of all ages have moved to Nashville. Even L.A. session great, Mr 335 Larry Carlton, made the move a few years ago.
