I bought an EZG a few months back used. It came in with weak tubes so I threw in a new set of GT's and a new rectifier. It was awesome but my son felt like it was lacking. We go to this amp tech, imagine house full of Nos and vintage tubes, everwhere!
He adds a couple of resistors, 1ohm, so he can bias easier. The tech then drops in a RCA rectifier and two svetlana 6l6's NOS, adds RCA 12ax7 and a RCA 12at7. The amp is dead quiet now. I think it is biased around 23 but at the resistor.
It sounds amazing. It is not as loud as it was with the gt's biased at about 35 but the clean head room is amazing and it might be more manageble. No breakup with the post all the way up until just past nine on the pre. Chime is there and sustain is there with much more touch sensitivity.
This guy played with a bunch of tubes until the amp was silent. The reverb is spectacular now. I do think he is using a 12ax7 in the phase inverter though.

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!

roscoenyc: I have never in my life experienced tube rattle. That said, I've only been playing electric guitar for 49 years.

capofirstfret: I've experienced tube rattle in two different amps that I've had. In both cases I bought the rubber rings from Eurotubes and it fixed it for me.

GuitarZ: Idiot! I wanted to put a little air on my Zoom H1's circuit board to clear out any residual Deoxit from spraying the input connector. Guess which can I picked up to spray. Yup! Not the air can.
