So, All of a sudden my Remedy stopped working on the "half Power" setting! Don't really know when it happened - last week it was fine - went to the full power setting for a while-then went back to half - still okay. Turned it off last night....when I turned it on today - NOTHING!? I thought the whole amp died, but when I switched to full power, it's okay. But no sound at all on the half. Any easy things I can look at before taking it to an expensive shop??

I'm with Steve, power tube thing. When you go to half power on the remedy you are shorting the signal from two of the 6V6s to ground. It may be possible that you blew the two tubes that are sending signal to the speaker at half power. Weird, but possible. When you go to full power you are getting the other two as well and you get sound back. That is a guess on my part. Others know way more about the inner workings of them than me. When you go to full power does it sound like it did before at full power? Is it as loud and is the tone the same? If so I am likely wrong. Or is it as loud as it normally is at half power. To check out my theory you could start switching around the power tubes to different positions in some systematic way and see if you get half power in some arrangement of them. It would be nice to know which two go to ground when at half power. I would guess outside two or inside two but that is strictly a guess. An easier way would be to get 4 new 6V6s and sub them in. If it acts the same you'll have a spare set which you should have anyway and if it fixes it dump the old ones since the ones that didn't fail have been run as much as the ones which did .
Maybe switch the power tubes. From right to left 1,2,3,4. Swap 1,2 with 3,4. My thinking, if that's how the tubes are "paired" this would reverse the effect. 1/2 should work and full power won't. Just a thought.

put in a new matched quad....voilla! perfect! When I took out the old ones, I saw that the 3rd one (counting from the preamp tubes) had a cloudy top....I'm thinking that was the culprit. I'm throwing that one out, and keeping the other 3 just in case. Thanks guys for all the support here....great board and members!

GuitarZ: Needed some noise to fill a break in a tune I'm recording. It was too quiet. Just happened to have some High Quality Dr Z Ghia noise to fill the void. "Heal Your Sound with Dr Z! It's not just a guitar tone prescription!"

GuitarZ: Must be great to be a skunk. Eating bird food about 10' from our sun room. I'm clapping and yelling. At best, it might have given me one "yea what?" look while continuing to dine. At one point, there were two skunks and two racoons.

easyed: Guitar Z, I encountered to ultimate garbage raiding combo once. We'd been having problems with the garbage cans being raided by raccoons for weeks. Late in the evening I heard rattling at the cans. I went out and found that he'd allied with a skunk. "OK"

GuitarZ: EasyEd - Someone at work topped us both. The inside of their car had been somewhat ransacked. They were blaming their son. They checked the video. It was a Bear! I'll stick with the racoons, skunks, foxes, and squirrels.

bigboki: In this age and time when everybody are struggling and especially S&Ms I am amazed to see that kind of ignorance. I am really sorry for your experience dear Dr Z but it is for the better. You don't want to do business with those kind of people anyway.

GuitarZ: Didn't want to restart the plumbing thread, so I figured I'd ShoutBox this. How the heck does cleaning the aerator on a faucet cause a leak to start under the faucet? Huh? Arggggh!!!!

The Bad Poodle Experience: well, Mike, it shouldn't have been the cause of a leak. double-check your work.

GuitarZ: I updated in the Plumbing thread that the Moen website says that a faulty aerator can cause a handle/base leak. Eiyy! I really don't understand how plumbing works. I was ready to double check all connections. But, the leaking stopped with cleaned Aerator.
