          Ok, I shorted the power amp input and plugged the amp into a general wall outlet. The power tubes are always in.

          With no driver or preamp tube in. Absolutely silent.

          With just a driver, no preamp tube, Absolutely silent.

          with just a preamp tube, no driver, absolutely silent.

          I went ahead and deox the pins on the preamp and driver tubes. Time of day, deox, who knows. Amp shorted, pkugged into general wall socket, pretty darn quiet. I can't hear it at my chair. I can hear it at the driver and say 6 feet back.

            Rex is this an inter graded amp premap ? Of it is how is it at just above a max volume with inputs shunted ?
            does lowering or raising the vol effect the hum

              The amps are strait up monoblocks. 1x12AXa7, 1x6SN7, 2XKT77 or other variant power tube.

              My preamp is also duel mono. Independent power supplies, independent grounds, independent volume stepped ladders etc, just share a case.

              The boosted noise when the preamp is powered up is pretty constant until I get the volume quite high. Then the distortion/hum gets louder.

              Preamp has 1xE88cc and 1x0A2 per side.

                So is this good or bad? Maybe time to try some new or at least different tubes??

                  And how do you know they are $365 each?? They could just as easily be twice that, or half that. NOS tubes change price all the time, even from the same dealer. There are a number of people here with a variety of lightly used highly regarded 6922/E88CC/E188CC/Cca tubes who could probably help you out for less than $730/pr. Same goes for your power tubes.

                  I have been using Upscale audio tubes
                  His Tele never go down in price, only up. 2 weeks ago they were $365 each. I tried tele from 2 other people and got ripped off. Kevin has the real deal.

                  My setup likes the tele. I tried nunerous others. Im not totally opposed to othere. Siemens almost worked well. Just the tele are extended both e ds and very clear.

                  Which ones are they? There are quite a few Telefunken 6922 varieties from the '60's, though all are probably very good. Any reputable tube dealer gives a no questions asked money-back guarantee, and Telefunkens are fairly easy to verify (on-line databases for the manufacturing codes)

                Wow that’s a lot of hours. I can’t say if tubes as they age get noisy I’m not a tube expert. Is the heater AC or dc of These tubes ? If it’s dc this over time polarizes then Heater element. If it’s AC this can cause hum of caps or other components used for bad.
                Rex I’ll call you today ok.
                for now deflne quite please
                Also why do you say preamp in the amps.
                mid it’s at the amp input it’s a buffer not a preamp.
                amps on inputs shunted
                only output tubes take note
                at Speaker 🔈
                at 6 feet
                add driver tubes do as above take note
                add input buffer tubes do as above
                this will help me clarify things.
                keep this in mind this is the actual noise floor with no signal and it should be silent so any noise is not to be there.
                Also shut off all nearby stuff off.
                do the amps both sound the same ?
                analog stuff.

                  Generally speaking I dislike kibitzing a thread, but this one is so obvious I feel I have to throw it out there. With all your work and experimentation with power, cables, etc, you might have overlooked what will make the biggest change in your system's sound; simply rolling your various tubes. Even high quality NOS 6922's will probably sound more different than different cables, and I suspect this is also true for your power tubes. Just a thought.

                    i thought Kingrex was a master electrician? and he's dealing with hum and noise?

                    not to intrude on the subject, but this is becoming comical to me

                        You need to turn the 3rd photo just a bit to show the date and factory code... These appear to be 2 or 3 notches down from the "best" Tele 6922's (which may be nearly impossible to find NOS today)

                        Are you going to give us a picture of the factory and date code so that we can see what tube you are talking about?
