Tube Amp Archive

tubes are made by hand so to make good tube with constant and good quality means workers with steady hand , experience, tools within tolerance etc etc. to start from zero and claim superb production and attach immediately high price because of standard capitalism system for sure cannot come to life...

Some sold out but most are just sitting on what they have conspiring to see what outrageous pricing they can get away with. My local shop just got a big order from Euro Bob [even tho im no JJ fan] i asked what he would sell me a quad for. We are personal friends and even then he said " im not sure w...

That EH presser just mean Mike Matthews has greased the right palms for now that's why prices are jacked. We all know how trustworthy the Soviets are. [pun] Again, the game has changed and politics, War & corruption are now manifest in the Vacuum tube trade. Don't expect miracles. For all we know th...

JJ will crank out tubes at their full production rate. If they aren't running 3 shifts, or even 2, they will probably add those shifts as soon as they can train up enough skilled workers to make that a practical reality. I don't think the Russian-Ukrainian war will last very long no matter what hap...

In 1985 my EE Professor predicted vacuum tubes would be obsolete. Yes & no....

I'd expect russia to export tubes to china, which may then resell them, if not relabel them Don't count on it. I spent all day searching for an EL-34 quad. Every source ive had had last 15 years 0.00 unless you pay $600 to $1600 for NOS. Right now the new production EL-34 is basically extinct overn...

Thanks Steve >

I bought a variac to use with my 100 watt Marshalls. Thinking of running at a steady 115VAC. I have a modified 1978 JMP 2203 & a JCM-2000 DSL 100. I also use an older Furman PF Pro. Should i plug in the variac at the wall AC outlet then into the Furman then to amp or Furman into wall, variac into Fu...

Do you think the current Ukraine / Russia situation will affect Russian vacuum tube availability ?
