Fwd: Hopefully on topic

Hi all, I now have just acquired a VT-100 and am in the process of checking it out. I noticed there is a capacitor that has vaporized, but I cant determine what value it is. I have the DEC VT-100 maintenance guide but it is very blurry in the relevant area. I cant even read the board designation. This is the area of the circuit, I can trace the 2 Zener diodes on the -23V rail, to one end of the cap, the other end seems to go to ground. The obvious culprit is C6, but that doesn't match the mud map of the board, as in C1x. https://imgur.com/a/tm8mn8b This is the capacitor in question. It looks like C1x where x is undetermined. I think it was a ceramic monolithic capacitor, it seems to be different to any other caps on the board, i.e. slightly larger and a different colour blue. When I look at this hires photos on Google images, it is the blue capacitor circled below Does anyone have a VT-100 and mind checking what the value of this capacitor is please? Ideally value and voltage or even just the nomenclature written on it, I can work out the value and voltage from that. Many thanks and Cheers, Martin...
