    Default Wtd: EL34 valves

    Was just going to order some JJ EL34 valves from Watford Valves. But was wondering if anyone here have spare ones they no longer need.

    Looking for 2, 3 or 4 of either the JJ EL34L or EL34 Mark 2.

    But maybe something completely different and 'higher end'? In which case need a quad.

    What have you got?

    Cheers

    Hi,

    Just wanted to say I bought a matched quad of 'cryo' JJ EL34 valves from Watford Valves and found them to be a huge improvement over the stock chinese valves in my Icon Audio ST25 mk2. Thought they were good value for money to.

    Good luck with your search.

    Hi Rob

    Thanks for that. How would you describe the improvement you heard?

    I have wondered about cryo valves but held back as it sounds like there may be a lot of 'foo' involved and always on the guard for expectation bias creeping in. Interesting you found a huge improvement. I may do some more research to see if any validity. If I can't find some EL34s from this wanted post I may go in a different direction and get the Harma cryo valves.



    But still looking ...

    Yes indeed. Thanks for the reminder Alex.

    So any EL34s or KT77s looking for a loving home?

    Have you tried the Chinese (Shuguang) variety? From my experience they are better at producing good power valves than the smaller signal valves. You can borrow my back up pair if you want to try them. (I have JJs in my amp too).

    Is it a good idea to mix different valves.

    Thanks for the offer of a borrow Lawrence. Maybe when we next meet we can try things.

    For now just building up necessary JJ spares as two el34s are down and only got one working spare.

    Unless someone has a quad set of a different make.

    Sorry I meant matched pair of pairs, I should probably have said matched quad instead!
