Thanks! I assume that other hole is for the wing nut to lock it in place/stabilize?

Cool, thanks for the tips. Since I'll probably be drilling a bunch of screws in I might leave it bare. If it's not too much trouble. Also the diameter of the circle for pulling the board and distance from the edges. There are some measuremants on this page not sure if accurate...

What wood should I go with? Pine? Spruce?

My NAC is missing it's mounting board and I am looking to make a new one. I know it's some kind of composite; anyone know for sure? Looks like plywood but could be MDF? Not sure on the wood type.

Anyone have a copy they'd like to sell?

Do the original CDs work with this bios?

Recapped Blast City Two's PSU God this thing was disgusting. First the PSU looked like it had Smoker's Lung, blew out all the dust outside before taking it apart further. The dust + rust had embedded itself into the board but luckily it still worked. After washing out the boards and letting...

Been a while since I posted; a lot of different things have happened since! In the original pic the "Left" Blast City is BS1 and the "Right" one is BS2. Control Panel from Blast City One Cleaned and Back Together Got a new BC and AC panel from @alberto1225 and LOVE it! Put the thing together...

Well I got it to work for about 10 minutes with another flyback. Either I am unlucky and the flyback was also just about to die, I nudged something in the process of swapping the FBs fixing it, or something is killing the flybacks. Anyone have any guesses?

Tried out HV-Adjust and no change in symptoms even if it's set all the way left. Just raises uncontrollably and then is shut off by xray protect. Starting to think the mosfet is fried.

Well looking at the MS2931 manual which shares a lot of similarities with the MS2930; seems something with U701 and Q701 is broken, as it seems U701 drives Q701 to switch it on/off to stabilize the HV.

Been debugging this MS2930 that crapped out on me a week into getting a Blast City (you can read more in my project showcase thread). I have a thread going with Grantspain on the Arcade Otaku forums but might as well get more input here. Originally the monitor was showing no video or static on...

Well! Getting somewhere! Reinstalled the anode cap and the arcing disappeared, well there is a blue flash from the yoke still. However I am getting a white raster (I assume) for a second before it fades; probably due to the protection circuit. Feel static on the screen too! So tube seems good...

Further investigation in complete darkness I can see arcs flying off the anode cap and at the yoke. More investigation needed with the EHT cable (according to Grantspain). Transformer might be failing. Just to confirm but a necked tube only arcs inside the glass tip right? Still don't seem any...

Welp still no video . Was really excited to play this machine. I did notice that the HV squeal does return when setting the remote board to 15khz AMP. No video from my MVS board though. No static on the screen surface either. In terms of other things: Heater still turns on, no arcs that...
