Details:

Tubes carefully tested for emissions, shorts, gas, life and leakage. The maxi marcher is a useful tester for measuring current draw and trans conductance at plate volts with 5 bias voltage settings. Very good with 6v6s and el84s, this tester falls a bit short of true operating levels on 6550s, el34s, 5881s and 7027s.

Telefunken E91AA nos vacuum tubes for sale a pair of new in original box Siemens branded Telefunken made E91AA 6AL5Ws.

In my opinion, and the opinion of many tester experts, this is the best tester that was made by Hickok. The triplet 3444 is one of the finest testers ever made.

I use the us. Shipping us.

Exceptional in every aspect. Photo is of the actual tubes on offer.

Exclusively for shipping.

Fine print only place a bid when you are seriously interested in this particular piece and when you are truly willing to fulfill all the obligations according to rules. Tubes have the diamond and identical date codes. Guaranteed.

Still much better than most suitcase testers for measuring power pent odes. Money back on these tubes if they do not operate and test as described. All of my testers except maxi have been calibrated and redone by Chris hated.

Tubes are shipped upright, in oversized boxes with packing peanuts and bubble wrap.

No tube is sold that has any gas, leakage or fails life and strength tests. I do not trust the minimums on this tester and they are therefore not listed.

Superb with directly heated tirades.
