Selling three NOS Tung-Sol 5998 / 421a tubes for $225 each or $625 for all three. The set with rubber bands is a matched pair. Willing to sell individually. These are the preferred version of the 421a with bottom getters. Purchased from a reputable online dealer a while back but never got to use them. $225 includes shipping and insurance for each tube. CONUS shipping only. Message me for approved payment methods.

Selling as-is, no warranty implied.
