Depends what you short it to... short it to the cement on your floor and you're fine. Short it to the frame, as most people do,
and you may or may not ever see use of those frame grounded drivers again without that resistor. That's the difference.

How many machines are you working on right now BTW? Didn't you just score quite a few more?

No, I didn't pick up any more (other than SW and AD). I've got major restorations going on Pac-man and Centipede. Those are the two that will take over my life once the weather gets warm enough (snowing here today).
Front Line just needed the joystick fixed and a new CPO. Star Wars wasn't meant to be worked on other than replacing the yoke overlay. This monitor issue needs to be fixed so I can start stripping the parts out of Pac-man and Centipede.
(Oh, but I've got several projects lined up once these are done so don't worry. ;D Gyruss will probably be up after Centi and Pac are done)

You are getting snow at this time of year??? Wow!!! We only get snow once a year if we are lucky and even a half inch of snow shuts everything down here. I thought you were working on several machines, but I didn't recall that the Front line was nothing major. Two major restorations at once though is a lot of work. I hope you get this monitor fixed, it's nice of level 42 to offer to fix the boards for you though if you get in to much of a jam with it. Sounds like a major PITA you got going on with it right now (all I can offer is "good luck" with it, as its well beyond me) As always I will be looking forward to seeing The Gyruss and these other projects get underway (not to sound like I'm rushing you, but you do always do really good work)
Spyridon:
Okay, I decided to play it safe. Also, now that I have two vector games, it made sense to have the proper tools. I have just ordered a Fluke HV Probe (80K-40)
I considered pulling the monitor without discharging (after leaving it turned off for a few days), but decided against that once I read the instructions in the manual on how to remove it. You need to disconnect the annode wire to remove the game. No use taking any changes. Proper tool is on the way.
ChadTower:
Now that is definitely optional but good to have. I use a long screwdriver with a heavy wire, one end clipped to the screwdriver shaft and the other to the metal frame, then slide the flathead tip under the cap to the anode clip. You do need to be mindful of where your hands are but it does work fine and I know a lot of good techs who do it that way on location.
FWIW, that POP you read about doesn't always happen. In fact I've never seen it happen. The most I've seen is a little blue spark when discharging the tube before putting the anode back on (yes, always discharge a second time). Don't be surprised if you see nothing visible at all.
