How many netters still have the devices mentioned in their parts box?
My parts box was purchased at the ORGINAL Radio Shack store on Washington
St. in Boston (now somewhere under City Hall) 31 years ago.  Little
changed since then, I can find at least 10 of the named devices well-
organized in the little drawers!

Anyone requiring circuits for these well-aged devices, let me know, for
I also saved the early transistor circuit guidebooks from Raytheon, CBS
(2N255) and other long-gone manufacturers.

P.S.  Does anyone have an "01A" vacuum tube?  I need one for a vintage
vacuum-tube voltmeter.
