Default What to do with these Eimac tubes?

I have some NOS Eimac monster (250TH) and his baby (100TH) but I don't know what to do with them. I though to submit a thread, maybe someone come up with an idea

You can build an amp with them.. Check out the GM70 listserv on Yahoo groups for inspiration.

Well, since you don't have a pair of each, look at the price they go for on ebay what you want, to sell them and use the money to buy, say, output transformers for your other project, or buy one of each to get pairs and build an amp. However, it won't be easy to build an amp with either of them, but more so with the 250TH.

I'm also genuinely interested in building an amp with these tubes. I've been designing amps using old transmitter tubes for a couple years now and find them to be utterly fascinating. ARIYAHOOR, I sent you a PM as well.

You're overseas from North America?

I'd not ship them far, the filaments are fragile.

Best used for ham radio, imo.

But if ur in the USA, or North America, I'm interested...

I would imagine that once they get shipped off they're gonna bounce around in a truck, a plane or whatever - matters not whether they are going 50 miles or 5000 miles. And in this case they would be coming from Iran.

I'm still not sure why people always ask me for links when this information is just a one second internet search away?? Anyway...

Go to: groups.yahoo.com and then in the search dialog type GM70, and it will send you here: Yahoo! Groups: Search Results

You have to join, to do so click "Join this group" fill out the requested information, and then you will have to wait for the group owner to approve your application which could take a few days or more.

Hopefully this resource is not blocked in your neck of the woods.
