makes sense. I am one of those who don't like most dumbles, so I understand if he's still chasing. which circuit did he build?

Dumble? Isn’t this the Marshall forum?

Tubes are no.1 usual suspect

How many tubes did you swap in? Brand new ? Helps to get them ordered tested for microphonics and noise. Wouldn’t be the first time a new tube was pinging out the gate. What brand tubes? Fwiw I have found tungsols to be very prone to microphonics, also sensitive to parasitic oscillations . Always ha...

Pacific transformers will wind something for a more reasonable price . Send them all the specs , and don’t make a typo .

I also was suspicious Page's amp would use 6550's, though I wouldn't be super surprised given that the export spec used 6550s. In the intro to the manual Page claims he had his amps modified prior to mid-1969 when they started recording LZ II, which much earlier than I thought, especially since he ...

10k tail . Stock Marshall values .

no apologies necessary, I didn't detect any distasteful tone, my wording could have easily been interpreted as suggesting an alternate value bright cap. my bad. I had the chase tone, tried my hardest to make it work, but I prefer the real deal by far. the old ones punch in the low mids. as far as JP...

fwiw 12au7 IS what is in the Super Dragon. correct on bright cap, stock value = nothing, I just personally can't attest that is definitely the case in the super dragon. one thing to remember as far as compression goes, an echoplex ep3 will change the character substantially. I myself never play a su...

increasing cap to .22 with 82k would get closer to the target frequency. 91k would be even closer. Not sure about the bright cap in original, but I assume stock super bass value power filtering I am almost certain is typical 50/50 cans throughout, maybe 32/32 in the pre, but might just be a 50/50 as...

I imagine a vintage mkIII to retain and appreciate its value in time better, and trading it for an amplifier that needs a ton of work seems questionable

560p 270k v2 grid could be standard values for the channel mixer? Or is there a big grid resistor in addition with a bypass cap?

Nothing additional …just channel mixer… bright channel of course

Also, 47k nfb off spkr jack
