The peak voltage is 88 and can be reduced down for a more laid back sound. The bias can go back some too, and The feedback is way adjustable. break out the marshmello'

I can do that tomorrow. That is the eight bias adjust buttons and pots. -

I can try to do a PDF recreate of the manual this weekend , time allowing. Thanks for the warming Skip. I wa very Leary making adjustments at first. Jud did a hell of a job spelling out the do!s and Don'ts . I would to have loved to met Jud andMarianne in person. He is quite a guy as far as I can tell.

Careful man. Are they actually intended for variation? Normally the tubes are optimized to have those settings fixed. My 845 SET amps do have adjustable setting that aren't for biasing the tubes, but I'm not sure about yours.
I would second that thought. Normally tubes have a small range to work in when adjusting bias. Anything too much shortens their life and given the amount of tubes you have in there, might get costly.
I might also suggest if you plan on keeping that beauty, a small investment in a tube tester should be your next purchase.
Judd was also very specific in his manuals, a trait not often seen with today's electronics, as Bob pointed out. It helps immensely, so you don't make costly mistakes. It only reaffirms that the man put as much detail and attention into building his products as he did in his manuals.

What's Joule Addiction? All the time, I am only thinking we have Joey Addiction and his new audio ****; etc.
Trying out Different Audio Cables is a Religious Affair. You don't discuss it with anyone. :redface::biggrin: -
I would never exceed the voltage limits or the peak bias settings. You can reduce to change the sounds produced.

Bob, I hope your listening on a Sunday to that amp. Put up some impressions/comparisons will ya....I've been changing shorts every day waiting for your thoughts. F1NUT even combed his hair waiting, Russ shaved, and Brock already has a lineup of tubes for you to roll.HT SYSTEM-

Pass amp is back on line. I believe I had a power tube fail. I was getting some static/hum out of the right speaker. Then the volume shot up and the pre amp had no control and I had to pull the plug. I don't know how old these tubes are but I have some tubes coming next week anyway. This was an odd failure as I had no control and no fuses blew. The voltage was was less than 86 and I started to check the bias when it all went wrong. No damage and the Pass is working well.

I guess you can't test the power tubes with a multimeter. I will have try something else. Tony you mentioned a tube tester should be my next investment. Do you have a recommendation? I would like the option of testing the array of tubes being used. Thanks

Most of them do a good job Bob, the one Ron mentioned should suffice. I brought it up because of the amount of tubes you have in all the gear. It's a worthy investment especially with tube amps to save you from those situations you just experienced. Plus when or if you buy used tubes from someone, you can test them pronto and have that opportunity to send them back if they don't cut the mustard. Good tubes aren't cheap, you want that option instead of waiting 3 months before you try them out and can't return anything.
The old "ounce of prevention is worth a pound of cure" thing.

If I'm not mistaken, I think the fuses in most tube amps are designed to blow on a dead short only.

I am very happy with both amps and both pre's. The tubes have greater detail and a wider stage. The pass amp is easy to use and sounds fantastic. I really have not spent enough time listening to both combination.
I really like tubes for detail and I like the ss for turn it on and go.
When I get this joule vzn back up and running I can give a better detail. I am just finding out what tubes were sent with this amp
The 6dj8's are amperex ecc88's The 5751 are GE and the 6350's are Calvertron??
I am not sure what tube(s) caused the issue yesterday.
The 6c33 looks like a tough tube to test.
More to follow. -
Yep,, not the easiest tube to test. Did you happen to notice if any of the tubes red plated?JC approves....he told me so. (F-1 nut)
