Before It's off to the shop, perhaps someone can offer insight as to what may have happened.Careless handling has resulted in a dead left channel. I was putting the tube cage back in place after dusting WITH moist hands after a wash. Using what I thought were dry enough hands, that one drop of moisture dripped onto a power tube socket. The obvious happened-blown tube.
R/R tube and power up.Amp goes through cycle as usual, but of course dead left channel. All power tubes and preamp tubes light up.
Thanks in advance.
Any likely situation here? Hoping damage is minimal.

Sorry to hear it. Some months age did something stupid and knocked out a speaker. Only time it has happened in all the years I have played. Happily, it took out a cap but, no drivers hurt. So, rebuilt both crossovers and at the same time invested in a pair of improved tweeter diaphragmns. Definitely improved the sound and though not cheap the return in improvement far exceeded the cost. Went from the dump pile to my son grabbing them as his new permanent speakers.

Until I lug the amp(30kg)to a tech, I'm forced to use this 15 year old pseudo HK receiver. A far cry from an American 60's piece.
The PL is almost 10x the price and 5x heavier! The cost difference is easily heard. No more realistic vocals and band. Visceral bass from the REL is gone. This emergency only HK is awful.
On the flip side, the plastic remote controls everything and it doesn't act as a second space heater. Touch sensitive blue volume knob very 90's.
For $250 bucks, you got 80 watts with DUAL sub outputs along with sterile,dead sonics.
I'm not getting near my beloved PL with wet hands EVER again!
Try to enjoy it! I used an AVR40 as an emergency unit for years and always was surprised at how well it did.
I'm being a little harsh on the HK. Relative to the cost-$250, with a source, a couple of bookshelves/sub you have a system on the cheap.
It's listenable to an extent. The ears just get used to whatever you're listening to, which in my case is decent tube gear. I know a proper SS rig gives tube a run for its money, but this ISN'T an example of such equipment.
I'm preparing for separation anxiety!
I have had too many stereos suddenly blow out. Then be out for prolonged periods of time. Taking advantage of that philosophy I have a wonderful vintage tube stereo and a wonderful modern Hybrid pre/SS amp.
This is why I am so fanatical about having TWO primary systems. And I seem to also have two secondary systems for some reason I can't even guess why???

This looks like a Primaluna Dialogue Premium HP. If so, the bias circuit is protected by a breaker, not a fuse, and after it shuts down it should come back up if you wait a few minutes before turning it back on. If you changed the tube and turned it back on too quickly it was probably still in the protective mode. Now that it has been off for some time turn your amp back on and see what happens.
FWIW, I had this happen with my late model Dialogue Two and that worked, but on one occasion it did not and that led me to having to get a new circuit breaker.
Hope that helps.
Yeah, I referred to the manual, and did just that. No reset going on here
I'm aware there is some protection circuits in the amp along with the "reboot" sequence.
Guessing it can't be something too drastic since there's juice going to the dead side and the amp powers up as normal?
My amp turned on both sides with one side's audio output dead. Looked like it should have operated normally. Then I had to have the circuit breaker replaced by a techie who discovered this failure. If you are still under warranty you're good. Mine wasn't and Deal recommended a techie who did a good job and got it going by replacing the breaker. I think he keeps his techies available for repairs to his own sales (?). FWIW Deal didn't admit that a dead circuit breaker could be the problem. We gave him the dead one so he could check it out....
For what it's worth, I learned recently that some types of circuit breakers are only meant to be tripped once (supplemental breakers where they rely upon a more robust one upstream, like maybe a fuse, in audio).
but by quick research and input, it does sound like I blew the relay and it will need replacing. Since this is "operator error", now I can only hope this will be considered a "forgive in the name of customer service" and N/C for replacement. I won't hold my breath.
Same happened to me.
I just replaced the fuse for the left channel

I was thinking(hoping)that there is some sort of "safety" feature that's happening here.
I will check out my options here.
Have you replaced the tube?
Alan
did the obvious stuff-refer to manual troubleshooting. Off to the shop for what sounds like a relay replacement as posters are mentioning.
