The tubes listed below (unless indicated as NOS) are used and have
been twice tested (that is tested the second time just before shipping) for
mutual conductance, gas, leakage and shorts on
my Hickok 539C tube tester. All have tested as good functional tubes
well above the minimum acceptable level and are individually boxed.
Those of you new to old radios and their tubes, please take a moment
to read my notes (right column below) and other
info I have posted on tubes on tube numbering and style types, be
sure and look at the images I've provided by clicking on the (brown)
links.
Keep in mind that quantities are limited, some to only 1 or 2.
**Matched pairs The industry standard for matched pairs is 25%. I match a
bit closer that that, typically my matched pairs will be within 10%
but no more than 15% of each other. They will be matched for
mutual conductance & brand, the fee is
$10.00 per pair over and above the individual price.

The list below are 1920's/30's tubes. Both
"ST"
and
"Antique Globe" styles are included. If available in the
"Globe" style, they
will be listed with their original "UX" or "UY" prefix following the 2
digit listing (some globe styles do not have the prefix).

=======================
The differences in the
"ST"
& "Antique Globe" style tubes
are strictly cosmetic. The
"Globe"
styles are the early style & less common. They command a higher price because they look
more authentic when peering into the insides of the 1920's radios.

Vacuum tube numbers were not
standardized until the early 30's. At that time all the prefixes such
as "UX" and other extra numbers and digits were dropped. Examples:
No. UX-201A became a "01A", a UY-227 became a "27" and so on.
