[Techtoolslist] HP 1650A Logic Analyzer

[Jose Luiz Martins]

Hi Folks!

Continuing to put back to life my old test equipment...

I stored my HP 1650A Logic Analyzer in working order about 6 years
ago. I bought it used - I think it was highly used once the screen has
signs of burn on it.

Yesterday, when I finished to fix my Fluke 9010A, I've decided to try
the 1650A and nope...

The power source clicks and the voltages are not correct. 7V instead
of 12V, 4,5V instead of 5V and oscillating.

I have not experience in PS repair, but someone told me that the
electrolytic capacitors may be dry due the time it was stored (as well
as de condition, one it was in Rio de Janeiro, and at summer time, the
room temperature may be more them 120F)

Could someone confirm that please ?

Thank you very much !
