[ARC5] Tubes needed for submarine Cobia

[Reass, William A]

Yes Andy,
I know I have a few 4PR60's, brand new.  One is right here in my office.

I probably have a 726B klystron as well, but that will take some sleuthing and time to search the boxes.

I'll get with my ham buddy John Lyles (K5PRO) whom is a boat anchor "activist" .... and see what he has.

OK!!
Bill

To All:



For continuing operations of the restored SJ-1 radar

equipment aboard the Wisconsin Maritime Museum

submarine USS COBIA could you all please see if

you have any NOS (or known good)  tubes of the

following types:



726B Klystron   (Rx local oscillator)



5HP1 CRT        (A-scope display)



5D21 or 4PR60 (Tx pulse modulator)





The Museum has the following CRT's for trade:



1 - 5AP1

2 - 5BP1A

1 - 5CP1



Otherwise I would be glad to buy the tubes for donation to the Museum.



Thanks,
