Every week one or two Scopes from a company named "Gould" pop up on my ebay-watchlist for Oscilloscopes, but I haven't found any real useful information about them. Only that the pens for the integrated plotter will dry out and are quite expensive but are still in production or at least easy to get.
What I would like to know: Does anyone have any information about the reliability and the features of these scopes? Aside from just being curious, I almost bought one a few weeks ago and would like to know how close I came to burning 50€ or missing out on the deal of the month
We occasionally have a request for repair help for Gould's.
AFAIK they are resonable quality but unless you can find Service manual for any you might be tempted to buy, you'd be wise to leave it alone. IMO that applies to any old CRO.
These were an associated product offering when Gould Industries made Biomation logic analyzers back in the 1970's -80's.
Their idea and marketing goal was to get a share of Tek's portable scope market (dominated by Tek 465-475 back then).
Tinkering with them back then, they were not so great even when new.
Not recommended as they are difficult to support and service documentation and parts is very questionable.

I'm struggling to find a Gould 1425 service manual, the internet is bare :-(
I'm trying to calibrate input voltage and there are so many unmarked presets inside....
any clues where to look, maybe around the input stage?
Many thanks

Was this a digital one like this:
https://www.eevblog.com/forum/testgear/show-your-strangest-crappiest-piece-of-te/msg1807304/#msg1807304 - not worth any money IMO.
PM me if you want this one for free, but you must cover shipping anyway ...Edit: just noticed this is an old thread, so presumably OP isn't interested any more, so I withdraw my offer.
Yes, it was something like that.
I've created a small collection of Philips Scopes by now. PM3320A for doing actual work, PM3323 to repair (mostly done, but still has tons of drift over the first 5 Minutes after power up) and one PM3323 as spare parts-supply for the other PM3323
Which means I'm not interested in the Gould scope
I'd suggest selling it or using it for high voltage stuff.
