Re: NAME THIS AMP

Even though I won't be there I do like the idea Made at Carver Fest (Date) on the back and have Bob sign the front in Gold with the Kit builder also signing under Bob's name. Of course in Silver, Bob gets the Gold! :-k That would be cool to have your own name along with Mr. Carvers on the front!

Double O,

I know, you can make him an amp and sign it for him! :lol: :lol:

We all could aid in making 1 extra amp and all sign it and present it to him![/quote]

Excellent idea! =D> =D> =D> =D>

Sure. I think you turn all of the pots up as far as they will go, power up and bias down, right?

This is going to be so much fun and quite the learning experience. =D> Will remind me of my 10th grade chemistry lab. Although back then, I was surrounded by a bunch of hot teeny bobbers, rather than a bunch of "geezers." :rolleyes:

As an example, I have no idea what any of the above means, other than the power up part. :shock: Never thought I would have a tube amp or two! 8)

I don't think I will have to worry about Bob's new Ebay ad featuring "Tubular Don" instead of "Tubular Joe"! :lol: :lol:

Do NOT bias this way!!!!

Don, I was kidding about biasing that way. If you do, you might take out all of the tubes, resistors and possibly the transformers if the resistors didn't do what they are supposed to. George is just razzing me because of what happened with one of the Anthem1 tube amps I had.

Truth be told, I went to go bias one of them [George's old black faced Anthem1 amp] and tube 1 was fluctuating all over the place when tube 4 had lost its glow altogether when powered up. I could not find a way to stabilize the fluctuations, so I swapped out tube #4 with a known good tube. As soon as I powered it up, tube 4 got as bright as the sun and I thought I blew the resistor before I could get to the power button because it had let out the magic smoke.

I do not have a tube tester and I had already ruined 1 quad of rather expensive tubes [They almost cost as much as I paid for the amp itself]. So, I gave up. These were the first tube amps I have in the rig, besides the Cary, that I had to manually bias. Normally, you connect the negative DVM probe to the ground and the other to 1 of 4 voltage check points and you start with all pots turned down all of the way. You slowly rise each of the 4 tubes to the voltage you want and periodically check after that for drifting which was normally minimal. Maybe .02 volts or something miniscule but enough to knock out certain aspects of the imaging and/or sound stage.

What happened that morning was the variac on tube bias #1 was fluctuating between a full 4 volts and .001 volts and it would not remain steady at any point. The test point on tube bias #2 was the same way. I just could not get anything to stabilize whatsoever, even with all pots turned down to nothing.....which normally shows 0.00 volts. As soon as I swapped tube #4 out, the magic smoke appeared before I could power her down. 1 tube had blown at Carverfest last year due to the voltage issues with the cabins and me running the bias a little hotter than the recommended bias. Now I was down to 1 tube from the original quad I had ordered and that I wanted to save for a spare for the other quad I had for the other Anthem1.

Well, long story short, it sat here for a couple of months as life kept getting in the way for me to dig into it and find out what was going on. I finally had some time to go down to Atlanta and visit Jerry [Who has a shitload of tubes at his disposal] who said that he'd be happy to take a look at it. He called me two days later and after fucking with me, told me that George's amp has been running fine for the past two days. What? I asked him what he did and he told me that he simply put in another set of tubes, biased it and that it had been running fine ever since and that he's been enjoying the hell out of it. To this day, he's been running it with no issues whatsoever.

I need a tube tester. ](*,)

Re: NAME THIS AMP

We have a very nice tube tester, and a big ass variac. I will bring both.

Good deal, James!

Cool. I meant to pull out my antiquated tube tester last year and see if Bob could figure out how to use it but time got the best of me. Well, that and I forgot. #-o
