This is a great forum! Thanks to everyone who helped me with my questions and concerns. I have learned a lot, met some nice people on the way, and got all the information I have asked for.
Now I know how to adjust the bias on my JOR. It is actually no big problem, and could be done by anyone in a short time. On my JOR, the bias on all four tubes was still within the specified range, but after adjustments, they are now perfectly biased again.
Hello, maybe it is not the perfect place to address my question, but as a lot of people owning the JOR seem to be here, I give it a try instead of opening a new thread.

So: does anyone compared the Tungsol 6550 reiusse to the SED SV6550C? I use the Tungsol reissue now, for over a year or so, that has replaced JJ KT88's. I'm quite satisfied with them, but some say that the SED SV6550C is one of the finest if not THE finest, so maybe I should give it a try?

Also: we use the JOR with 220mV for the output tubes instead of 110mV. Some expert examined the JOR, and said, that it can be a problem, the transformators won't be injured or whatsoever, and the sound will be more lively and dynamic and it is. The only problem that can happen is that the output tubes will last shorter. So we use it this way for a year and a half now, and no problem appeared at all. Would be interested in your opinion about it. Of course I DO NOT advise it to anyone to try in his/her JOR. I did it for myself, in my JOR, that I'm responsible for.
