I was working on my Battlezone monitor a few days ago and I was replacing a set of 3716 and 3792.

Since I had finally had the right parts I decided to replace the TIP42 that I had in place of a U07 (mounted it at the top of the heatsink then ran wires down to correct the pinout). While I was at it I replaced all the old sinked transistors in the V and H deflection circuits. I wasn't paying attention and I was in the hurry to get it back in the cabinet and get it tested because I had some other stuff to take care of... anywho, I swapped the NPN and PNP transistors (U07 and U57) that I had just put in and when I went to test the monitor it went off like a damned roman candle... I fried 4 resistors in the V. Deflection circuit and a 3904 transistor as well... and bombed out those brand new 3716 and 3792 I just put in... le sigh.

I've replaced everything that was obviously bad (the resistors and the 3904, I checked all the other transistors and they're testing good as are the diodes) and I'm ordering in another set of 3716 and 3792s (I'm just going to call them the cans because I'm tired of typing out the numbers).

I still have something that's throwing me off though... without the cans installed, the spot killer still comes on. When I turn the brightness up I can see the line down the middle of the screen... but shouldn't I be able to see that line, at normal brightness, even without the cans put in?

If that's normal, just let me know... if not, then any ideas as to what I should be tossing the shopping cart while I'm ordering parts? (besides more patience and the ability to read a letter and 2 numbers off a part before I put the voltage to it)
