[Lenox Carruth]

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.
