Hello I have an old 1910-1920 temple radio I was wondering what metals are found in these tubes and circuitry yea that's right circuitry Deos anyone know what's in them
I actually do a lot of gold and platinum refining and would like to know more before I rip it apart

Our Stance on Refining Topics - DANGEROUS
I wanted to make a sticky in here about our rules regarding precious metal refining. I don't believe there was ever a clear thread or notice regarding this so I'm posting one now.
First and foremost - Refining involves chemicals and processes that can KILL you. Refining is DANGEROUS. That is not to be taken lightly, trying to refine, without knowing what you're doing, can KILL YOU and OTHERS AROUND YOU.
This forum is not the place to become knowledgeable about, or to educate others about the details on how to refine precious metals.
We don't want discussions starting here with detailed posts about how to refine, the mixture of chemicals, how to or not to be safe about it. This is not the place for that type of discussion, refining is an entirely different trade from "Scrapping".
Detailed postings regarding the refining process have always been and will be continue to be removed when they come up. Again this is serious stuff and this forum is not the place to learn or teach these things.
If you want to learn about, or talk about gold refining (or the refining of other precious metals) please visit the Gold Refining Forum 'GRF'.

Thanks!
Re: deleted video.
.It's obvious by your safety practices your not a member of the http://goldrefiningforum. Dude your going to shorten your lifespan by sticking your bare hands into metal salts, the MSDS sheet shows copper acetate as a toxic substance,
With your level of knowledge or lack thereof your demise will probably come from accidentally making an explosive compound.
Please remove your video. Thanks Admin.
Those vintage vacuum tubes probably have much more than scrap value to a collector, check out your numbers from the tubes on ebay or one of the vintage radio forums.

I don't think tubes contain any precious metals, especially old ones. They do, from my reading, contain Berylite, a toxic ceramic material which you would likely disturb before you even began any acid work. Tubes of that vintage will yield better than scrap value to collectors with much less risk and work than PGM refining.
A radio of that age will likely be worth far more as a collector item by ham radio operators. 73, Mike
I read somewhere that the 'Getter' can be toxic so don't break open the valves.

No worries, I have been refining precious metals for years you guys really don't need to worry about my practices but I do understand your concern and that's why I would really like to know more about vaccume radio tubes and compenents found in the early models it seems as tho I can't find much info about early 1920s tubes and compenents the newer tubes from the 1930s and up don't interest me
lmao the clown mask filters all the nasties
Do the tubes work?
Im Not sure if i want to plug it in, its like extremely vintage looking !!! And sorry about posting my videos i wanted to share my videos with like minded individuals and maybe generate some revenue and sales, i wont post any Refining stuff on either forums anymore.
Plug it in, if it works way better than refining or scrapping it. I would like to see a video of that working, could be some easy money...
PSA:
NEVER plug in a tube radio before testing each tube in a tube tester. Old radios very greatly but it only takes one WEAK (not just blown) tube and the whole unit gets toasted. Testers are not cheap so if you don't have one, find a radio buff or ham radio guy to test your tubes. I personally save every tube and tube radio I come in contact with.
Faceball is correct; as tempting as it is to hear that warm, sweet tube sound, it can be potentially destructive to your device. Always test, first. However, if you have a working tube device like a radio and you have a guide to tube interchanges, you can "fake" a tester by inputting tubes into the appropriate sockets. A hardware guy I know swears by this method, though who knows how many units he's smoked testing blown tubes.
I picked up an NR-71 tube tester from a nearby enthusiast for about $50. It's not top of the line but it will perform as well as anything in that price range. Audiophiles seems to swear by the $2000 brands like Hickock but you would have to be seeing a pretty regular stream of tubes to make that ROI.
Really, though, you can sell even untested tubes removed from equipment as "pulls," which pays less than confirmed, working tubes but is practically no work and no hazard. Put them on eBay as an auction and let the market decide or join some forum like AudioKarma and see if they show up on some collector's wish list. Tubes don't contain any metals valuable enough to justify even scrapping them, let alone getting out your rubber gloves.
Kiwi is correct that the getter can be toxic. Though shiny, it is more likely to be barium or strontium than anything valuable to a home refiner.
My dad says that taking apart tubes can kill you because they hold a charge not sure if this is fully true or not, I feel like tubes are an ancient technology that predates Christ lmfao
he now won't let me take apart his crap
Yep, don't waste your time or risk trying to extract anything from old vacuum tubes.
Get a cheap tester (cheap by the time you sell a few tubes), test, sell. You will make a crapload of money from each tube on ebay ($80 each), far more than any precious metals you'd spend time recovering (not to mention time wasted on recovery).
If you want to recover precious metals, look at switch contacts and other electrical wires (modern CPU/IC are good), perhaps high performance spark plugs if you can find them.
Silver switch contacts are alloyed with 12% Cadmium which is nasty - so do research these things and proceed with extreme caution.
Thank you for pointing this out.

This IS serious. 73 Mike
