[time-nuts] hp 5372A Parts available

[Dave Powers]

Howdy - I am interested in the bottom board and the power supply stuff - as well 
as the CRT and the CRT circuit board with flyback transformer. I don't 
necessarily need the pods. Wondered what you want for what is left and shipping 
to 67207 - Wichita, Ks - Dave Powers - KA0KCI

A1-A6 board have been sold to a buyer in Brazil.

The only logic bard I have left is the 05372-6008 (A8 I think).

I still have cosmetic parts like the the front panel top bottom and sides. I 
have all the sheet metal internal stuff and all the power supply boards and the 
power transformer.  I also have 2 54002A pods.
