Questions about tubes and gear that glows. FAQ
Given the thread below on the questionable reliability of JJ tubes, in your opinion does this lack of QC also apply to the 2A3-40? The general consensus seems to be that these problems exist with the octals, not the power tubes. I'm currently running the stock Sovteks that came with my Ultra-Fi monos and they sound good, but are perhaps a little lacking on "punch" and "air". If the QC issue doesn't seem to apply to the 2A3-40s, for those that do run them, where do you prefer to buy them? Jim doesn't appear to carry them, and of course there could be a good reason for that (as he's already stated) but without mentioning this particular tube.
If not the 2A3-40, then what? Jim does carry the EH 2A3 Gold, which could also be an option, with the advantage of knowing they've been properly checked before shipment.
