The ACTP tests good but doesn't have any metalising and its 4V but I have only one.
The TP2620 tests good, looks NOS but probably has little application with its 26V heater.
The TP22 tests good and has metalising.
The ARTP1 tests good as a TP22 and has metalising.
So why don't you have either the ARTP1 (TP22) as I have another good TP22. Or the TP2620. I wont ever use either, they have been up in stores for >10 years and will still be there in another !
There isn't much call for the TP22, the last one had one bidder on Ebay:
http://www.ebay.co.uk/itm/MAZDA-TP22-radio-valve-tube-/331273660583?pt=UK_Collectables_RadioTelevision_Telephony_SM&hash=item4d2172e8a7
As for the TP2620 I cant see it ever being needed.
To me one of those valves would do more good sacrificing its base to make the tester work.
Anyway up to you, its there if you want it.
