Sure, but for GND there are even more (three) pins already available...

My last attempt was 3 diodes (1N4001) in series, lowering the voltage on pin 13 from 12V to about 10V and still everything worked. From my experience with a dead C90, I know that there is a voltage where everything still works but the picture loses color. For the 6569R3 involved that was about 8V. I ordered two adjustable switching stabiliser modules from eBay/HK. This test (I still keep it in my mind) I want to do once I get the modules. Should arrive next week /me hopes. -- SD!
