[Jhoe]

Guys you have any idea where can i buy "VLVE-00092 for my marshall 100H, i decided to replaced them all because the output was very distorted, i have this problem before but i reduce the bias output and solved my problem, i used it 1 to 2 months and it happened again that is why i am going to replaced them all

can you please help me to find out where can i order, or any replacement for my bad tubes

You don't need to purchase Marshall branded tubes.
You can generally get those from the place you got the amp.

Go to tubedepot.com and you can get everything you need there. If you need to, call them and ask which might be best for your needs. They have a very large selection of tubes.

Thank you.

Do you have any idea for replacement for the tube VLVE-00092 with 46mA..
can you recommend me any replacement for the tube.
i already checked on the internet but the tube VLVE-00092 was not available

I thinks these are a good replacements: - Groove Tubes EL34M or JJ if you want to go discount.
You will probably need a matched quad if it's a 100 watter

I would go with a matched quad of Tungsol EL-34B's and make sure to bias.

If you're serious about biasing your own amps you need one of these ...

I bought tubes from Nesstone a couple times on Ebay with really good results. I bought a quad of EL34's that tested really close. I install a pair & keep a pair for spares for my 40C.

No
I would never buy "NOS" "tested" tubes.

I have no faith in "tested" old tubes. I know how many defects can occur and I know "testing" isn't accurate.

I know we have bought "tested" old tubes, and about 7 out of 10 were defects...

Buy new tubes, and stop screwing around.

If the amp has a problem: start with new tubes.

Replacement will never be the same part number (VLVE-00092) as a factory tube.
The current reading is rarely the same as the original. Don't expect it to be.
That's why the bias is adjustable.

I also know that a normal "tube tester" tells you about 40% of what you need to know. It is not a definitive complete test.
Don't believe that a tube tester tells you everything, cause it won't.

I did that also and wasted time, the seller had 4 "NOS" power tubes i only needed a set, ofcorse the first set had issues so it took me 3 weeks to get the amp going when if i would of just bought NEW i would of saved 10 days waiting for shipping. The second set he sent me were ok but i wont go threw that shit again on "NOS" crap

I saved maybe $15. but it wasnt worth the time i wasted.
