Tubes for CarverFest 11 Tube Amp

Had a runaway tube as soon as I plugged in the amp to give it a play- For the EL84's I got the new "reissue" Mullards made in Russia- should be here tomorrow. Will post results upon listening. Here is a link with options for those that need these toobz!

There were not enough good tubes at the fest. I got none.
I had these there: http://www.amazon.com/gp/product/B003X5MUDE
Bob was interested, tested them and said they were strong. He also liked them because they look so good. He told me it was a good choice.

Here is a buy on the others : http://thetubestore.com/nos-6ax7.html

Bob also said he would look into tubes and later recommend some tubes in the $7 range.

Mike is building my amps, and I am going with the JJs and maybe the above 6AX7 if nothing better shows up.

Bob talked highly of Electro-Harmonix tubes

I like the JJ's in my AN set up.

I'm with ya', Bill. 2 amps and not one tube.

I have a feeling this thread will be a long one as folks try different flavors of tubes in the amps. I look forward to hearing some suggestions. So far, all I have heard is Mullards sound pretty good but I don't know for which application they were referring too when I heard this.

Hell, I BUILT the amps, and I walked away with "0" tubes

While at the Fest Jerry gave me some Hammond Amprex (spell check) tubes, when I asked Bob about the 40-50 year old tubes, he said, "those are my favorite!!" apparently, he had a small stash of them that he brought with him for testing, but they got lost in the 5 day mess of a build.... Someone, or a few people were lucky enough to get Bob's secret stash of tubes!

Dan, Just a question . Did you install the zener diodes in the biasing network . If so you need to snip them out or snip one end and see if they are shorted as this could be the cause of the tube going cherry red.

Whoever has them, they need to be returned to Bob.

Those are some good tubes.

Thanks Harry- I do not think I added the diodes, by the time I got to that phase Bob had already decided they were not necessary. Roy helped with the network portion so I will have to double check to make sure... I think it was just a bad tube. I was helping test the tubes and it seemed like 1 of 7 were bad-give or take.

I popped the Mullard reissues in this morning and fired it up.......GREAT TUBES for a GREAT AMP! This little puppy is amazing to say the least!!! A little TOO good for an office system.....can't get any work done while the system is playing, but I don't want to turn it off!!!

can't get any work done while the system is playing, but I don't want to turn it off!!!

Have to sacrifice something, don't let it be the music!!!

Good for you Dan, HAPPY LISTENING

Alright, folks.....please take the time to check what tubes you have. If you find them, please let us know. These are Bob's, not yours.

There is no harm, no foul as the tube build was pure discombobulation [concerning parts] at best. Point being, these belong to Bob and collectively we need to get them back to him.
