Hello,
this looks filthy - I take that we almost have a deal!
The switching power supply can go out, if you feel like being able to sell it on.
Regarding the displays: so you do not want to desolder them, but take out the whole front panel PCB? Or what? Sorry, I am a bit confused - if you want, we can have a phonecall or a skypecall.
You could have as much or as little as you wish, except the lead and connectors. The overall weight, which is largely due to the very solid chassis, is 10kg. You might like to consider having only the various PCBs
I've just partially disassembled it to see what's in there.
The first two pictures have the display on the left and the PSU on the right.
The third picture shows what you are really interested in: the display boards. I've lifted these out, and you can see the connections are -18V and +180V (yellow dots), and the control signals applied via a comb connector between the red dots. I believe this is "connector B" in the manuals, but you must verify that for yourself.
The fourth picture shows the naked panaplex and neon displays; damn they are just
beautiful! Makes me wonder why I am prepared to let them go
PM me with what interests you.
