Default Anybody know "Trio" oscilloscopes/tone-generators?

When I was a child I remember not being able to sleep because my farther was testing amps and loudspeakers using a tone generator......

Forty years later I am in a similar situation - the audio hobby is genetically heritable!

Recently, I have dug out the equipment used by my farther including an oscilloscope (Trio CO-1303D) and a tone generator (Trio AG-202A). Knowing my farther he would have bought the "second-best" so maybe this gear is still useful besides the emotional value.

The units works perfectly when powering them on after 30 years of disuse. My idea of recapping the oscilloscope unit was a bit discouraged after opening the unit - everything is wired/soldered so carefully that disassembly will be very complex.....

Advise or opinions anybody?

Cheers,
Nic

If it works leave it alone. Bad caps would show up as hum or an out of focus trace.

No focus problems. Square waves are so sharp that I cannot see the transition lines :-)

Agree, leave alone unless you have experience of servicing these. Also beware that model of 'scope has about -1200V on the cathode and an acceleration voltage of about +7.5kV!
