Hi everyone,
I just checked and the rectifier tube that went installed in my second hand LSS is a 5U4GBEH Electro Harmonix Made in Russia 02 06. That's all I see printed on that one. I know the amp was build to use a Philips JAN 5Y3. I know too from MB that my amp is above the first series that had a higher rate of failure due to lower specs modern tube, that the current JJ are way better than the russian that were used a few years ago and failed often.
So, the "Made in Russia" on my EH makes me suspicious, and also 5U4G is this the same as the 5Y3 in spec? Does it have an impact on the tone of the amp (different 'sag'? don't know neither what it means nor the effect it could have)?
Should I search for a NOS Philips JAN 5Y3? Or maybe you can point me good and not too expensive alternatives?
Many thanks already, this forum is so rich in advices, hindsights, amp settings and much more that I can not stop reading it at the mo .
Thanks already for you help and advices.
