Friend and I played with Amigas yesterday and I can confirm that connecting pin 1 and pin 7 stops it going up. Going up doesn't start again right after I remove wire but after some shorter or sometimes longer period.
Is this enough to confirm that resistor pack is bad?
Are these the one that need to be replaced?
All of them or one? What are their exact number and value which should I know when searching to buy them? Are they fairly cheap and common? If they are I'll replace them all. I mean I'll give it to someone who knows.
