The tubes listed below (unless indicated otherwise) are used and have
been twice* tested for mutual conductance, gas, leakage and shorts on
my Hickok 539B tube tester. All have tested as good functional tubes
well above the minimum, acceptable level and are individually boxed.
(* tested the second time just before shipping)
Those of you new to old radios and their tubes, please take a moment
to read my notes (right column) 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 a very few.
Matched pairs* are limited and if you desire such, let me know
if you don't find any listed. If not already listed and I match for Gm
only, the fee is $5.00 per pair, to match for Gm & brand, the fee is
$15.00 per pair over and above the individual price.
* The industry standard for matched pairs is 25%. I match a
little closer that that. Typically my matched pairs will be within 10%
but no more than 15% of each other. |

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.

=======================
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.
