Picked up a Tek 100MHz 7633 at the Blackpool radio rally also for
£40. It had a knackered timebase switch barrel which was eventually
cured by the taste of a soldering iron bit. Have now had 2 years
faultless use out of it.
Yesterday I was checking out part of a mixer circuit using a
badly decoupled 74AC86. Noticed a low level 1Vpp signal on the scope
screen, wound the T/B to max, then even had to press the x10 button,
to see the very clean, perfectly triggered, 205MHz!!!, sine wave
indication of the 74' chips self oscillation. I know it's passe' for
some of you well equipped guys out there but having always had to use
30MHz scopes (tops), this was a revelation!.

scopes and all my other superceded kit ... the council dump.
