The 6N2P will only work if you can rewire the filament connections in your radio
to support tubes with 6.3V heaters. IMHO the E european 12AX7's are much
more likely to suffer interelemnt shorts than the best JAN USA tubes. But they
probably aren't any worse than what the TV repair shops sold in the 70's and
80's.

I believe that Allied now has 12AX7's in their latest catalog (2007) again, for
$12.75 each. Probably branded National, probably Russian.

I was working on the fact that many of the Allied tubes are National brand labels
of imports, but didn't actually know about their 12AX7's. Sometimes National
branded tubes are really NOS made in the USA from the 60's or 70's or 80's.
I'm not so sure now: the picture in their catalog of a 12AX7 is late 70's GE
production, which almost certainly would've been made in the US. May be
irrelevant because their stock is currently zero!

Keep in mind the 6N2P tubes have a 6 volt filament. You will have to rewire the
filament line going to the 6N2P to 6.3 volts to get it to work. May cause
problems down the line if the mod is not clearly documented on the chassis or
near the tube socket and someone tries to plug in a 12AX7. May be more
trouble than it's worth to modify a radio to use them. 73 Todd WD4NGG

I have as many 6082 tubes as you like for $12 each (tested). I have a lifetime
stash of them. (I am out of town until 12/28, so don't expect a reply until then)
