I am insterested in some if you will send me some pics please.

Maybe I can use some stuff and figure out a project or two
to use with my high school students.

I don't know why this thread took a nose dive...bummer

They were part of some things I grabbed from a telephone microwave relay
station that was being done away with. Actually have some other oddball
tubes, thermal relays inside a vacuum tube enclosure and other odd stuff
if anyone is interested. Can take and upload pictures of the stuff too.

I don't understand why the thread lasted as long as it did!

The 417A makes a jolly nice little one-tube amp for sensitive speakers
(the kind that comes free of charge out of trashed tube radios) and at
a reasonable plate voltage too, so the power supply can be cheap. See

Head cans, maybe.

I have approx. 32 (will have to go look for true count) NOS Weco 417A
triodes in their boxes. 1970s date codes. Genuine ex-telco stock
(we used to use these for voice band amps in Type V3 4 wire repeaters,
as well as a ton of other applications.) The 417A was also used in
broadband carrier systems for HF applications, as well.

What am I bid? Failing a tantalizing bid, I'll sleazeBay them to the
Orientals.
