My trusty Telequipment Serviscope S51A has decided it doesn't want to play after being in the (dry) loft for years. On initial power and warm up it did work apart from the X shift. Turned me back to three seconds and the trace disappeared and the normal combination of Y and X shift can't locate, even reflection/scattering, of the beam. B-( Reseated all the valves but to avail, they all glow nicely though.
Yes it's an antique but served my purposes well but I suspect it's going to need extensive fault finding. So I'm thinking that a decent budget modern 'scope is on the cards. Not looking for anything special The S51A only went up to 3 Mc/s and maximum of 1 uSec/cm.
Anyone got recommends/avoids for makers or models?
