[Test-Equipment] Hickok 288X signal generator

[Brian Burns]

Hello All,

 

I just acquired an Hickok 288X signal generator thinking that this old timer
would be entirely tube based, and hence within my pay-grade for restoration.
Imagine my surprise when removing it from its cabinet that the first thing I
saw was a printed circuit board with 5 integrated circuits! Four were Texas
Instruments IC's with numbers like:

 

Z7647

443-7

 

The pcb was labeled "Heath", contained all the circuitry for the 10, 100,
and 1000 kHz markers, and was clearly a stock part, factory installed.

 

I'm not sure when the unit was made, but the IC's are surely around 50 years
old, and I would guess are no longer functioning, and that replacements are
non-existent. 

 

All of which leads me to the question of what to do with the old girl. As it
stands it's just a box of parts for me, but I hate to tear into a well made
piece of gear that might be restorable. 

 

As the man wired home on arriving for the first time in Venice:

 

"Streets are full of water-please advise"

 

Cheers,

 

Brian
