Obtained a Tektronix 2215A for a slightly borderline £58 delivered. 60MHz 2 channel crate with delay timebase. Slightly more than hamfest fees but my test gear was costing a car on top of previous purchases so that is a good deal. It looks like it works absolutely fine but has the usual problem with focus which I will describe below...
Firstly money shot. Quite tidy
Guts
Our first problem. As always the HV divider chain is drifted thanks to the rancid old carbon comps and some clever person has tried to fix it and failed. Actually failed quite badly at fixing it. There are supposed to be 4x 510K resistors there and we have 1x 656k, 1x 503k, 1x bodged 340k (the replaced one which has failed terribly) and 1x 636k. Doh!
And of course the usual cracked RIFAs. This time only the Y-class capacitors so not good not great. The main X-class is not a RIFA which is good news.
Mouser order will be fired off once all the gear I ordered turns up and has been evaluated.
