Yep, and there's only one in the bag.
--- Quote ---The kit I got (for an -02 board) had 2. Yet the board itself has 5 of those things. The way to figure out which to replace, is that Bob's kit comes with a handy little sheet that tells you where! Bob labelled every part according to the position on the board. If you look on the board, for example, every capacitor is named, such as C1, C2, etc... Resistors are named R1, R2, and so forth. I forget what the transistors are named, I think it's Q1, Q2?? Anyways, just look on his sheet for that number, and then match it to the correct position on the board.

My board has three pf the square parts (I guess they're the transistors), not 5. And my kit didn't come with a sheet of paper.

ChadTower:
From the 10.3: 11.64
From the 5.0: 5.1
Is the 11.64 acceptable?
RayB:
I get the same kind of readings. Should be acceptable. It *IS* high, but what can you do... If you lower the voltage knob, you'll get too low on the +5...
Did you measure the +12 on the game board (assuming there is one, or is the +10 on the game board??)
Should be fine. How's the game board doing? Working or hollering?
ChadTower:
Hard to tell what the game board is doing. I have only an audio hum and a faint glow in the neck (no spot killer). I'm going to take a hard look at the edge connector tomorrow and test the leads on the PCB. I just wanted to make sure the 10.3 value wasn't out of acceptable range before turning the sucker on for too long.
Should I retin the edge contacts? I haven't done that yet but have been shown how.
