[TV MAN]

Very interesting. Thanks for the information Ron and Arran. It sure is a shame we don't have any plants here in the USA. I checked prices on those tubes, both the 12AX7 and 7591a and I have to say I had sticker shock! I have come across a few pairs of the 7591a tubes for a reasonable price, but most are nothing short of stupid. I kind of expected that, tho. But, I sure didn't expect our own NOS USA branded 12AX7a tubes to be quite that pricy. I guess I understand why so many of those Fishers are sold knobless and tubeless.  If I recall, for awhile, there weren't any new production 7591 tubes. I think I recall one new production brand (been some years ago) that you had to change a resistor or something to make it work. At least they didn't rob the tubes from the IF strip. Missing the 6HA5. Well, still doing reading on AK. Some very interesting forums on this type of project. Trying to decide what kit to get, or if I should get the separate parts. Still got to get the electrolytics. And still thinking of Hayseed, but they are a little pricy. May be simpler tho.
