The five (5) tubes offered here are one Radiotron type UX-200A, one UX-301A and three UX-201A vacuum tubes.  They all tested good on my tube tester, except for the US-200A, which none of my testers had a setting for that tube type.  Two 201As tested in the 50s and the 301A and one other 201A both tested strong, both close to 80.  The tubes all came out of an Airline rectangle box unknown model radio.

All my tubes are guaranteed and if there ever is a problem, please contact me and I can send a replacement, if available, or make a full refund.
