I’m open to offers I’ve seen many mixed prices on these items. And as far as I know everything is in working condition they were recovered from a clean out / hoard. And everything including the original Sony vfets I had all six matched pairs worked. Numerous tubes sold on eBay and no complaints. That’s about the best I can give u on that. I also have two others that are very similar to this particular one. I know one is Soviet and not too sure on the other But all appear to be very very similar in size and shape and interworkings I hope that is enough info for you I apologize I’m new to this
