Re: Gould/ Advance OS3000A/ PO Oscilloscope 16A
Hi Tim,
It's good to see that somebody else is playing with one of these! They don't seem to crop up very often, but I've had one since I was a teenager. I remember driving down to 'Stewart of Reading' to buy it second hand in my parents car (Austin 1300 of course!) when I still had my provisional licence!
It served me well through my days of repairing Tv's, vcr's etc and then into timelapse security machines. I've always liked it to use and it's been pretty reliable until a year ago when it suffered insulation breakdown on it's heater winding.
Since getting round that problem with a separate heater transformer, there has been a cascade of failures, the latest being a very non linear trace on some timebase settings.
I was kindly given an OS3000 for spares ( sadly with a soft tube) so have used the timebase module from that for the time being.
I've pressed an old Hameg HM203 into service to repair the OS3000A, You definitely need a scope to repair a scope!
Good luck with yours
Cheers
Nick
