I'd still try an "inexpensive" set of Amperex 12AX7's to hear if you like the difference. In the Joule amps replacing the stock 5751's with Amperex 12AX7's gives a fuller sound albeit a tad less detailed. Jud bought what could get a big enough stock of which we don't have to do. We can hunt for small numbers of the tubes we like( it is getting tougher but not impossible). I think it's good to try rolling for yourself. I had a Calypso pre amp that most liked the Mullard CV-4004 '81 or one of the M-10's gold or steel pin. I used the CV-4004 until I tried an Amperex Holland 12AX7 and found it was a fuller sound that worked better for me, anyway you get the idea.
Joule electra Pre Amp -tube rolling
time to roll some tubes on my la 100 mk2. Quick review of some of the forums seems to convey that the joule is less sensitive to tube rolling and thus NOS may not be cost effective. Any thoughts from prior owners/experimenters would be appreciated. May be just a case to simply call joule an order up what ever they use. The line up i believe is:
1 - 5751
1 - 6350
2 - OA2
2 - 6EM7
Thanks all
