Default Re: Oscilloscope not used in years

They do Mr B and often die when first powered up.

If it were mine Brett, open it up, check that all the valves are there and no valves gone to air, they will be white if they have, and have no getter silvering.

Next check that all resistors and caps look ok, post some good quality pics here, some members have eyes like hawks and can spot a dodgy component from 1000ft.

Give the valves a wiggle, check there are no dead spiders etc sitting across EHT components and GENTLY power up on a lamp limiter. A variac would be better, but you haven't got one.

These are good scopes to cut your teeth on, being pretty simple.

Andy.
