no longer for sale

Here is a very rare tube, the type 5998 made in the USA by Tung Sol.  These are a superior version of the 6AS7G or GA, the 6080, and the 421A.  I have a limited stock of 1967 dated military issue tubes like the one in the picture, and they are unused new old stock.  This tube is in super high demand and supplies are very scarce today.  Prices are likely to double in the next 5 years for this tube.  These test as unused at 14,500 to 15,000 Gm on our Hickok USM118B where 9000 Gm is minimum good.  The triodes on the tube are matched to within 5% or closer.  30 day Satisfaction Guaranteed warranty.  IL residents pay 10% tax, outside of IL there is no tax.  We ship worldwide, all shipping is by first class mail only.
