I turn off my amp and switch some tubes last night, now only one side of the speakers is playing. I re-installed the old tubes back in and its still the same issue. It's a Shanling STP 80, also, I tested the none sounding with the souding side speaker and the speakers are all good to go. Dont know if I messed something up HELP! What can be the issue?

Had my unit checked out by Decibel audio, one of the tube socket was loosed something so simple but the baby is now fully repaired and functional :) Selling her as well!!!
A bad tube can make one blow.
Are there separate channel fuses, even inside the case (be careful inside there)?I've shorted a preamp voltage regulator by not waitng an hour or so for caps to fully discharge before replacing tubes.
Impossible to troubleshoot from afar, but check everything upstream, reversing wires, etc. If it comes down to an amp channel out without a fuse as the culprit it's best left to a qualified repair person.
If so, maybe inmates can steer you to a reasonable service center in your area.
Been there, done that, can relate and hope it ends up no biggie.
Well, I havent open the case since I am concern about breaking the Shanling seal. I have reverse the wires, rechecked everything, re install the old tubes, install the new tubes, turn the unit off for hours, turned the unit on and still. I hear a faint audible signal from the none working side, but the working side works perfectly. Man I feel like giving up on tubes, its such a pita but the sound is soooo good!
It's your property.
This will not void the warranty.
Only unauthorized repairs or mods would void it.
Amp companies do not want you to open it because there are hazardous voltages inside, even after power off.
Give it a half hour and then remove the cover.
Now do it!
...keep things in perspective and believe that it'll be something simple and inexpensive.I've had solid state gear with repetitive failures, so tubes alone are not at fault.
Advice that I've given myself many times, but only lately accepted, is to find reliable gear (even if not the be all and end all - none is), reach a level of enjoyment that is yours and no one else's, and accept the final setup as "permanent until something breaks". If tubes, try to have reliable gear that uses cheap and easily found replacements and replace them like you would tires on your car - well before you think you'll suffer a blowout from excess wear.
Did you replace the Power tubes? If so try switching, left for right, on the upstream preamp or phase inverter tubes. Likewise if it's the preamp tubes you replaced, try switching the downstream tubes, left for right.
I tried the smaller tubes but not the big ones, will do that later on. Tired of dealing with it for now, need a break. I have a headache
...seem basic but it's always a starting point and often the problem.
Bad tubes were the culprit, I am getting the amp unit verified and checked out to see if anything else went wrong but so far she's running beautiful again! Tubes are so sensitive!
I open the amp up, all the fuses are good to go, switch the tubes around and my right side plays good but my left side doesnt. No power, there is sound but is faint if that. Damn, did I damage my amp?
