I've owned my Z Lux for about 2 years, and bought it new from a dealer. The reverb isn't working and only makes noise, which I can eliminate when I turn down the reverb level. I replaced the reverb driver tube with no change. In troubleshooting, I can plug in the foot switch and it seems to fix the issue for a bit but I typically don't use the foot switch live - just set the reverb level and turn down the tremolo. I'd prefer to not bring or keep up with the switch for smaller gigs where I don't need the tremolo.
I went to the shop I purchased the amp from and they are no longer a dealer.
Sorry John but I'm having trouble understanding your issue completely. The Reverb FS only turns off the reverb by shorting the return signal to ground, this is why a shielded cable is used for the Reverb portion of the two button switch. So with the FS connected you can turn Off the reverb, hence stopping the noise and the reverb effect "for a bit" , is that right ? Without the FS connected the Reverb will always be active , controlled by the Reverb Control Pot. And Trem. needs the FS to turn On the Trem. effect.
If you swapped the Reverb drive tube and the Reverb recovery tube ( you didn't state you swiped that ) then the reverb tub itself maybe faulty.
Would you be so kind as to give your serial number as well as the dealer and date you purchased this amp from new and did you register your purchase ?
Serial Number is AA-38224, purchased from Toneshop Guitars in Addison, TX. Can't remember if I registered it to be honest, I own 4 Dr Z amps (Maz 8, Max 18, Cure and Z Lux) and have never had an issue before.
It seems to be working right now. Once I plugged in the foot switch, the reverb started working again and the noise stopped. When it wasn't working, I only got noise from the reverb and no reverb effect, if that makes sense.
I changed out the 12AT7 tube only, that is what the shop told me to do. This is the second 12AT7 I have gone through which seems like a lot. At this point should I do a full re-tube? I used an Electro Harmonix 12AT7 as they is what the shop sold me and said is the correct tube. It's been gigged about once a month since I've had it but the power tubes still sound good to me.
Sorry if this is all vague, the problem seems intermittant for now. Now that I've plugged the foot switch in, the reverb works wether or not I use the pedal, which seems odd.

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.
