Unfortuntally mine have no values printed on them. I'm replacing all caps as they are pretty old and getting some intermittent problems.

Hi guys, I'm recapping my bootleg WB monster land PCB. I've found all the values for the caps except the green mylar ones. Anyone know the values? Or can I work it out somehow? Thanks,

PSU replaced all working. Was completely dead. Would have been more expensive to recap and find the problem than a new one.

Right so cleaned up the board a little and visually inspected it. Some of the orange caps look a tad bulging. I'm thinking to attempt a recap as the PSU is pretty dead. NO green LED either. Looks like there are about 16 caps. Are these readily available still? Thanks,

My PSU is a Hantarex US150. Multi meter reading now reporting 0v power on pins 3-6 JAMMA connector. (On V mode DC). I've checked by using the actual soldered pins instead of sticking the probe into the jamma sockets. So I traced it back to the psu. I removed the molex connector stuck black on...

Ok after setting to V (AC) on multi meter I seem to get 14.x volts on pins 3-6. Is this normal? Because I think the Konami Wonder Boy Monsterland PCB requires 5v on pins 3-4 ?

ok thanks. The PCB is Wonderboy II monster land. The arcade machine is a generic JAMMA one. IT looks like my PSU is not preforming correctly, take a look at this video: https://www.mediafire.com/file/vgz1uo1o7j24j2a/IMG_7226_2.MOV/file Im getting strange voltages from the first few pins. I'll...

Could it be that the JPAC does not need the same power requirements as WBML PCB?

Hi guys. I've been using my machine as a mame machine with a Jpac up until now. I've secured a WBML PCB (Bootleg) which the owner tested before sending out. (seems legit). The PCB has a hacked jamma connector soldered onto it. I connected the board to my machine and nothing. No sound. No...
