Yesterday I acquired my very first SA and to say I'm excited is a gross understatement. None the less, the past 24 hours have been spent explaining to those who don't want to know and/or don't care what an SA is, what it is, and why this 30 year old piece of equipment was worth as much as a couple of business class domestic flights to one of the state's we're not permitted to visit (from Sydney).
The unit is ex ADF and they did a wonderful number on it - they installed an C14 cable dangling out the back with a "115VAC for Fan Only", and sure enough it was only connected to the fan (and only the fan).
None the less on delivery, 240V (on the 240V input, mind) let the smoke out which appeared to be a couple of capacitors that had failed - an easy enough replacement given stock in the shed and a handy bargaining point. After tidying it up and cleaning out some of the 20+ year old schmoo inside, it powers on and this time the smoke stays in. However the CRT is a bit janky and it looks as if the signal (the _video_??) isn't being drawn on the CRT.
I'm still in my 20's and haven't had to opportunity to be electrocuted by CRT voltages yet - so we're in uncharted territory. What do we think this drawing/rendering problem could be and where should I be looking? Power supply? XY board? What are your thoughts? I should mention that startup doesn't appear reliable however it appears to be related to temperature on the PSU section at the moment given the absence of a fam (I know, I know) - "Inst Check I"
Video for effect and perhaps to better explain what 'janky' means. Also some pictures because, well, why not, this thing is beautiful.
