I will see about those connectors. The 555 is pretty far down in the repair queue, but
it's important to me to get it running eventually.
In other happy news, I repaired my Tek 575 this evening. It had physical damage to the
step generator switch that was holding it in an impossible mode (single-family AND
repetitive sweep) and a bad 6AL5 tube in the step generator, so the step capacitor never
got discharged. It works great now.

I am pretty sure the conenctors were standard (full size Blue Ribbon
ones). I dnn't know if they're still made, but you might fidn them
second-hand sowmewhere. IIRC it's a straight-through cable, and it's jsut
pwoer lines (include the AC feed to the heater transformer in the
'scope),. so the calgbe is not too critical. Ypu might be able to make one. However the service manual for my Tektronix 555
'scope does explain how
to debug one half of the unit usign the other half (this is a ture
double-beam ;'scome, apart from the CRT and low-votlage PSUs, it's almost
2 'sopes in one box, so you can use one to diagnost faults with the other).
I too have a Tektronix 555, but I lack a power supply umbilical. Do
you have any clue as to where I might find one? I've been meaning to
join the well-known TekScopes list; I should do that and ask there as well.
