I find that I have about 40 type 813 tubes "in stock". All these tubes
are either removed from unused equipment or from used surplus gear. The
only rig I have that uses them is my ART-13A transmitter and I'll never
use these extras in my lifetime plus 100 years! Each and every tube has
been tested in my ART-13 transmitter and compared with a new tube at the
120 watt output level. Each tube was at least as good as the NIB JAN
tube. I'm asking $10 (which is exactly what I paid) a piece and actual
cost for postage. I also have a plethora of 1625's for $8 each.
