Dating tube boxes is based on educated guesswork from (a) when the These RCA boxes can hold the Holy Grail of vacuum tubes to most.
Probably the most used tube of all times in the final amplifier of “boat anchor” transmitters is the From the early s until at least the s, the found its way into virtually every manufacturer’s line of transmitters. In fact, during the early s RCA had a series of advertisements on the back cover of QST that listed a different manufacturer’s equipment that used the each month.
There are actually three distinctive variants of the basic The , A, and B. It is unfortunate that the B was called the B for it is really a different tube from the first two. Primarily the difference between the “plain” and the A is the makeup of the heater “filament”. The A has what RCA calls the “dark heater”. This “dark heater” is supposed to be more resilient to vibration, work well at a larger “range” of voltage, etc.
Otherwise, the and the A are the same tube. In mid RCA introduced the B with the “claim” of Also, it was “claimed” that the B could be directly substituted for the earlier tubes. You can see this in the attached copy of their ad from the September issue of QST. Many amateurs are aware that the military “ruggedized” version was designated the W I will get to these tubes a bit later. However, RCA also introduced in the early s the tube for use in commercial mobile equipment.

This is a list of vacuum tubes or thermionic valves , and low-pressure gas-filled tubes , or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics. Many industrial, military or otherwise professional tubes were also produced. Only a few types are still used today, mainly in high-power, high-frequency applications. Receiving tubes have heaters or filaments intended for direct battery operation, parallel operation off a dedicated winding on a supply transformer, or series string operation on transformer-less sets.
High-power RF power tubes are directly heated; the heater voltage must be much smaller than the signal voltage on the grid and is therefore in the In some valve part number series, the voltage class of the heater is given in the part number, and a similar valve might be available with several different heater voltage ratings. The system assigned numbers with the base form “1A21”, and is therefore also referred to as the “1A21 system”.
Often designations that differed only in their initial numerals would be identical except for heater characteristics. For examples see below.

Amongst other things that I have decided to collect, one is tube boxes. They all address my nostalgic advertising fancy. With that in mind, here is an alphabetical sampling of my vintage tube box collection, with any anecdotes I can provide. Keep in mind, too, that I bought many tubes at ham radio swap meets not even knowing what the tube inside was, but the unique box compelled me to add it to my collection.
Dating tube boxes is based on educated guesswork from a when the tube first appeared in any of my tube manuals I have dozens to refer to and b articles from past issues of Vacuum Tube Valley dealing with specific tube type history. He appears to be a walking encyclopedia of tube companies and their history. His anecdotes appear where relevant, and are marked. I wish I had more friends like Brent. Steve provided some very unusual tube boxes, and I am grateful for the opportunity to get my hands on them, and share these with you all.
Very cool! Without further ado…..
