spent a nice evening with my gottlieb volcano. has some switch issues which i believe I have solved. also had some audio issues which appeared to be associated wit the edge connector as it would appear/disappear when I wiggled it. took the board out, reflowed the connection pads and cleaned the two pots. audio is now stable but the sounds are considerably different. when i hit the spinner its repeats "volcano" it appear I lost "throw me a sacrifice" and "it's gonna blow" (it already blows). also it appears to change background sounds sequences. seems like what I thought was multiball background sound comes up too fast. it doesnt say eruption before multiball and when the game ends whatever background sound was playing just continues to play. looking for some advice so it doesn't "continue to blow" any ideas?

Thanks man. I will locate the connector stuff i need. I think theres a big yellow/orange cap i am supposed to replce at the bottom of the cabinet too.

i just placed an order here for a bunch of stuff:

I have not. I cant seem to find a list of what to order and I dont want to go pull them all out to find out and my paginated pdf sucks with regards to part #'s and values. Got any shortcuts for me?

BEAUTIFUL!!! THANKS SO MUCH STEVE!!!

LOL. I ALREADY DID THAT ON THE EDGE CONNECTOR TRACES

replaced the edge connector on the sound board and rebuilt the big connector between mpu and driver board. still no sound during gameplay or test mode but oddly it does play sound in attract. I suspect I may have damaged a trace but after a quick visual and continuity test things dont look bad going from those edge pads to the nearest component. I have not put it under the magnifying glass yet though. any thoughts regarding when the sound plays? I have the sound board caps on order so I havent replaced them yet but I dont suspect they are the probelm since I had sound before I uhhhhh "fixed" it. also I do have a black hole with what appears to have the same sound board. can I swap it in without changing the chips to troubleshoot with the understanding that the sounds will be different or will I just ruin that too?

"System 80, I want to smash it into little pieces"

holy cow man. whatever the outcome is here. I owe you a few beverages of your choice. pinside is awesome. really appreciate the direction!

I think i forgot to mention there is a niwumph mpu in there

hey steve. i swapped sound boards with black hole without swapping any chips. the no-sound issue followed the board into the bklack hole and the black hole board did mahe one sound when a game was initiated. caps are coming tuesday. i just ordered a schwemmer sound and speech board from k's arcade without thinking whether or not it would play nice with the niwumph mpu. any idea on that? also I still would like to fix the original board so I will replace the caps when they come in. if it's not those then I will likely send it to someone. I know k's does that too.

this thing is kicking my ass. no audio in game play but has attract sounds. put the swemmer audio board in. same thing. swapped driver board, same thing. swapped what looks to be a power supply (top left board), same thing. rebuilt A1J4 to A3J, same thing. rebuilt A6 edge connector, same thing. pushed all the wires into all trifurcon connections in backbox, same thing

was going to swap mpus as they are both niwumph but it looks like I need program those things with an rs 232 cable. I'm kinda baffled at this point and probably need to somehow learn exactly how this thing works rather than re loading the shotgun with parts and continuing to blast away... or just put both barrels in my mouth

unfortunately not. i could probably sway the roms with my black hole but I figured the new swemmer board would rule out the old sound board when it did the same thing. the only thing I have not changed is the cpu. it had sound before I decided to "fix" it lol. prior to that it was intermittent and wiggling the edge connector on the sound card triggered symptoms/no symptoms relative to the current state.

SWAPPED IN NEW ROTTENDOG MPU. SAME ISSUE. GONNA TRY CHECKING THE GROUND ON THE SOUND BOARD

ok now I smoked z13 and the niwumph mpu so now i have a rottendog driver board and mpu along with the swemmer audio module. that is indicating I am missing 12 volts and 30 volts via the board mounted leds so there's no sound at all. I'm not sure where those are derived from and the pdf manual i have is terribly incomplete so two questtions. if iz order the manual from steve young will it be complete and/or do you know where to check for the 12 and 30 volts supplies? all fuses seem to be good.
