Through an odd turn of events, I just took possession of 18 boxes of random NOS tubes. These are from a shop that started in South Texas in the late 40's. The tubes have been in storage since the early 80's. The tubes were stocked for consumer electronics (TV's, radios, etc.), two-way radios (HAM, CB's, public safety), and even some broadcast transmitters. Here is a quick picture of the boxes that didn't fit in my vehicle. Here are contents of just a few boxes: I took these sight unseen hoping to find a few jewels for guitar amplifiers. I was expecting 4 boxes but it turned into way more. Needless to say, I am completely overwhelmed here. I have no idea how many tubes I have. It has to be thousands, maybe 10 thousand or more. I suspect that a vast majority of these are of little use for anything other than vintage two-way radios. HAMs must have used a lot of tubes.... I am starting to group by box size, while searching through a short list of desirable numbers for guitar applications. That seems like as good of a plan as any. What else should I be looking for? There might be some decent audio tubes mixed in, that are of interest to forum members. Post some suggestions and I will add them to my short list. Any other advice on my new hobby? There were also two boxes of large Mallory capacitors (in addition to the other 18). I have not researched what those are for and if they have any value. Wish me luck. I need it!
