OK, I figured this would be scrap but I have more time on my hands than I n eed. I just found the other horizontal board which was lost, and I think I' ll switchum, but if that doesn't prove something and make forward progress, maybe it's time to get my mad scientist cap on.
So anyway, recently it occurred to me - why don't I just drive the damn pla tes myself ? Just how much voltage do these CRTs take ?
OK, I will never do as good a job as Tektronix did, but hey, it's now a par t. Not apart, but a part. It is a CRT with integral HV and focussing circui ts as well as a working vertical channel.
This ain't so bad. I can generate a friggin sawtooth and invert it into a c ouple of voltage amplifiers. At this stage of the game, if I am in the driv er's seat I could forego the regular functionality of the usual scope and g o for more specialised tasks.
An engineer in the 1980s would have creamed his jeans for something like th at. The 1990s even. Actually, for what I got into it, I am not pissed off.
So I am thinking various and sundry testers. I already figured out just abo ut the best lytic tester using the thing, another could be one of those poo rman curve tracers, you've seen them if you are old enough. But there are o ther things. Want to test an inductor ? Hmm, pulse it and see what follows. Just have the trace already locked anyway because YOU (I actually) generat e the signal for the DUT anyway. Mwaahahahaha.
So I am going to do what I am going to do, but I am acceptinng applications for new applications. That is, if you got any bright ideas I really would love to hear them. Hell, a curve tracer wouldn't be that hard since I got a calibrated vertical. There's three, but out there are millions of all kind s of things for which some new little thing can be devised.
Data, don't forget data, and another thing, this "part" can be easily quad traced. Also, the horizontal pluguins DO work in the vertical slot. In fact they trigger and free run, which they don't in the horizontal slot...
DAMMIT. Forget fixing it. Adapt it.
I dunno, what if I wimp out and get it running right ? Then what ?
OK, I'll change out that board and if it doesn't work it is getting the tre atment, the surgery, the genetic modification. You might think it akin to a sex change operation but I want to give this thing as many sexes as possib le.
