As Euro arcade collectors we all know about the good (excellent picture) and bad (several issues) things about the Hantarex monitors, esp. the 900 (not the 900E).
One of the problems is always the $&^&)&^# transparent HV cup. I mean, what were they thinking, hey let's make it transparent so we can see if there's anything flashing under there ??
And this while everybody knows that transparent plastics start to get brittle after about 30 years. Tsss, they should have thought about us then

Anyway, we are stuck with it. I've seen several "solutions" for this. Kit, glue, other goo-ie stuff....it's all only a half-solution.
The real solution would be replacing the cap with a non see-through one. I think I found a source for these (one's you can install on an existing HV lead) BUT of course Hantarex tried to improve things and used this weird two-wire HV lead with the "connector".
They describe it in the manual as an improvement. Anyway, what I want to know, what is in that little "connector" ? I think it's a resistor and maybe a capacitor ?
The manual shows this:

My guess it's that resistor and cap on the left of the tube, leading to ground (R144 and C96). Anyone know if this is correct ?
With these values we could try to find a replacement lead.
