Not for me..
Without those fuses, you get no XY signal at all, it doesn't turn my spotkiller on, but then again, I haven't found the problem yet! I just keep blowing them. I have neck glow, but no picture - and both of those fuses blow on power up. I will update later, I just got some parts today.
From what I read, the spotkiller gets turned on IF you're getting power through those fuses, but the XY isn't generating anything (thus the spot). I could be so wrong though, I don't know what the heck I'm doing. But without those fuses, you're not getting any XY signal, thus no spot at all. XY output is fine I guess, just too much for the fuses.
Anyway, if I come up with something over the next hour or so, I'll post it!
