<grin> The 175 is an insane unit. It is wired internally with welding cable and has an exceptionally serious power transformer. All the switching is done using major-league relays. It has a 200A

You may check adjustment 5 in "Display and Z-Axis Adjustment", Vol. 1 page 4-33 in my Service Manual. Adjustment won't interfere with 'scope calibration. Raymond

... My 7623 does the same warm-up readout drift. Where is R2527 on the 7633? I can’t find a “thermal balance" on the 7623 schematic.

Hi David, A little over a year ago I completed my Vacuum Tube Curve Tracer adapter which worked with ALL Tek curve tracers. After seeing the beautiful job Glydeck did on his simple triode curve

Hello Albert, Bingo! The idea was to show the S-52's signal into the S-4 so having the S-52 in the same mainframe with the other stuff made that simple. Yes and not really: Yes, the 7S11 in the

Albert, Good to know that GPIB doesn't work when it has hung. What's our best hypothesis for why it hangs? -Kurt

I have two 468's they do exactly the same thing at the fastest sweeps. Takes over 2 divisions before I have a trace.

I would be interested in buying 2 extenders (parts kits) if they become available again. Happy to commit with a deposit.

Hi Kurt, I tried GPIB to no avail. Albert

Based is probably a little to strong of a suggestion. Definitely siblings, though. Both were developed in the same time frame, both were designed to host a fiber optic readout system. Both are an

If you're interested primarily in tubes, you should check out the uTracer which is a very clever implementation using pulsed power supplies and a computer for the analysis/display. Google uTracer and

My 576 cost me - precisely zero! Known to have the epoxy HT transformer problem. I rewound it from the specification sheet, and potted it in wax. Works absolutely perfectly. Craig

Hello Raymond, Two things you didn't mention explicitly but follow from the 7854 photos: - You used internal triggering. Yes, but not triggering by the S4 (with I previously thought and couldn't

Hello guys, On my final attempts doing an overall wrap-up to my 464, to eventually put it for sale, it always annoyed me the disappointing performance (to my taste at least) of the Z axis intensity at

My main interest in a curve tracer would be for tube testing/matching. A few months back, I believe there was discussion of a home-grown 576 fixture for that. For now, one of my upcoming projects is

My CSA803A has become a 'frankenscope' inspired by Hakan's similar effort, so I can't claim any originality. I bought a scrap 11802 and used the acquisition module from it, which includes the delay
