Agilent 33250a worth recapping?
« on: March 18, 2023, 01:41:58 pm »
Hi all,

I bought a 33250a listed for parts for 200usd, the problem where the rams and the PSU, both of the problem have been resolved.
I was thinking of recapping the whole device, both psu and instrument board, buying high quality electrolytes and tantalum smd's, what I wonder is if it makes sense changing also the smd tantalums. The board was buillt in 2005 thus is 18yrs old.
The total cost of recapping is 70 eur, is it worth it for you?

If it was for personal use and it works good, I'd just (maybe) replace the tantalums as those can fail by a short :rant:, but replacing the electrolytes wouldn't hurt either.

If that ends up being your "go-to" signal generator, and you end up having 18 trouble free years of usage, then that would be a good investment.

18 years? Hah, I wouldn't touch it. If the tants were properly spec'd, and I'm sure they were, I'd especially not touch those. You'll just put more wear and tear on the board that it doesn't need. If something breaks, fix it, otherwise, leave it alone. They used good quality parts and unless you see some visual problem or it doesn't meet specs, you'll do more harm than good. I've got similar Agilent equipment at work that's been running 24/7 for 20 years with no problems at all.
