Black Hole progress


Recommended Posts

Here is the playfield before the stripdown.

 

Mylar, Black paint around the bumpers, shitload of glue (yellow pain in the arse stuff):realmad:

 

Its been touched up before as its coming away easily as acrylic paint does with the ethanol.

 

During the rub down with mylar removed with a heatgun.

 

You can see the glue that I have to deal with around the roll over areas, after the black paint removed around the bumpers the wood is revealed.:o

 

White smears are the remains of the rubbing alcohol for some that aren't aware.

Do you think I should cover with mylar or just a few coats of wax, what are your suggestions??

 

Wax?

Mylar?

top work, I couldn't spot the touch ups until I looked back to see what was damaged in the first place. how long has it taken so far ? and what type of paints did you use? if you have used 'hard' paints like automotives or hobby enamels then wax will be enough, acrylics then I reckon clear or mylar...

The power supply has been updated with recommended changes/fixes as per the pinrepairs site.

 

R10 with 680ohm resistor

R3 with 12k

CR6 with 18v zener

CR7 with 8.3v zener

POT1 with new 500ohm trim pot

IC1 socketed and LM723CN

 

I replaced the red LED's with a yellow LED for the +5v and green LED for +12v just so someone knows it has been worked on.

 

Also new elec. caps. all round to just make sure all voltages/signals are smooth.

There is a rottendog PS in the backbox but I wanted to fix the original up.

The paints are acrylic's so mylar it is then, don't want to clear with this one.

 

Its taken a few hours here and there.

Replaced caps, resistors and bridges with all new ones according to specs and checked all wiring on main power supply.

Bumper driver boards under playfield updated to fix the design error from gottlieb.

Check to make sure it hasn't been done already, if not reccommended to do.

 

6 in total to do.

 

2 x 4.7uF caps

1 x 100uF cap

10k resistor

1uF tant cap

removed diode - replaced with jumper

 

One of the 4.7uF caps is accross pins 4 and 5 on solder side.

Just a small update - needed a rest and still are.

 

Got the Novus 3 - 2 - 1 onto the plexi, although the pic doesn't show its full glory it was very scratched, but I'm happy with the outcome. Done by hand but might even see if I can get it like glass with power tool.

Will be procrastinating the application of this onto the playfield.

 

Not looking forward to it at all:o

I'll give it some serious thought as I will have to strip the underside of the playfield for 2 pac and I don't want to really.
