Has anyone re-tube one of these amps? I used 6550 for output but having problems finding the best 12AU7 and the 12AX7 tubes for the input stage. I have tried a few EH but find the sound quality inferior to the originals. It seems the new batches of EH tubes are not as good as the older batches. Could anyone tell me where I could buy stock tubes that are in top conditions? Thank you
If you're willing to spend the money, I have found Telefunken tubes to work very well in Jadis equipment; another alternative is older EI tubes. If not, agree with Wendell's post above, RAM tubes have sounded good in my Jadis in the past.
