DEC VT52 CRT anode connection

[Chris Zach]

Pretty much. I took apart my VT52 about 2 years ago because it wasn't 
happy. Turned out the +5 and +15 volt supplies were good but the -15 was 
bad.

After fiddling around with capacitors and transistors I took the easy 
way out and just put in a 7815 regulator, bypassing the old -15 volt 
system. Secured it to the heat sink and the display works perfectly now.

For something like that replacing old technology with new is OK by me...
