Hi Mike Was C3 in the circuit when tested? Usually a multimeter cannot pickup the ohmmeter/DC test on a 220pF capacitor. You should try the capacitor reading measurement with your meter. It still has to be out of circuit for measuring, lifting at least one lead/leg. If you jump the C3 capacitor with...

Ah, I see. That does sound like mentioned before, something acting up or going bad. Quite often people have problems with bypass jack contacts losing continuity in the loop and that cleaning them somtimes helps. Definitely find out what part(s) is giving the constant problem. I hope your amplifier c...

Then that is what is confusing. With nothing in the loop is the volume fading out or just lower than normal? The loop should be disabled when nothing is plugged into it otherwise the loop level controls will affect the signal level/volume. Maybe that is why Anitoli asked about the loop level being a...

I believe Marshall chose 100nF capacitors in conjunction with the ppimv for the VM amplifiers to retain the nice dose of lower frequencies to the power tubes.
Using double 22nF capacitors in series will affect your lower frequencies.

Hello Nugget I hope you guys do not mind me chimming in on this thread. I was reading it and just wanted to make sure I understood what is and what isn't. Nugget, so the volume dropped or began to drop when the EQ was plugged into the loop while the loop was enabled with loop level set to -10dB. Is ...

Gorgeous guitar!

I was thinking that the 6L6 types may be a little cleaner and less compression.
Which 6L6 were you considering?
Take a look at current 7581 tubes if possible. Reviews seem favorable.

The KT66 is a very nice and interesting tube. It is my understanding that both the KT66 and the 6L6 are beam tubes and designed to be kinkless. From what you guys have mentioned and I have read the Shuguangs have a little more to offer in the lower frequency range. Does anyone have experience and ca...

Awesome grab!
