Just finished the arduous task of replacing all the capacitors on the board out of my office’s SNK Neo Geo MVS-6-25 cabinet. It’s a monster, roughly 16″x20″ and two boards stacked one on top of another. The top board is identified as NEO-MVH SLOT6, while the bottom is labeled with NEO-MVH MV6. <\/p>\n
This monster board has a monster cap list, with a total of 39 capacitors required to totally fill it out. Thankfully they’re all labeled on board with which values go where (though voltages are NOT labeled so keep track!) The condensed list of everything I had to order is as follows:<\/p>\n
\r\n3x 1.0\u03bcF 50v\r\n12x 4.7\u03bcF 25v\r\n2x 4.7\u03bcF 50v\r\n1x 10\u03bcF 16v\r\n3x 22\u03bcF 16v\r\n1x 22\u03bcF 50v\r\n1x 47\u03bcF 16v\r\n5x 100\u03bcF 50v\r\n2x 220\u03bcF 16v\r\n1x 220\u03bcF 35v\r\n6x 470\u03bcF 16v\r\n2x 1000\u03bcF 16v\r\n<\/pre>\nI didn’t follow my advice and failed to note what exact voltages went where, but kinda felt it out based on the quantities and locations… Risky, but it worked. I fired the board up to test and the newly potent audio circuits startled the hell out of me since I’d left the volume slider at close to maximum from its previous weakened state. <\/p>\nngg_shortcode_0_placeholder\n
While working it over I noticed that a few caps have incorrect labels screened on the board. In particular there’s a pair of 4.7\u03bcF caps with 4.7K screened at their position as though they were resistors. <\/p>\n
Also ran a set of leads from the old battery location so I can locate a new rechargeable battery offboard once I source one. <\/p>\n","protected":false},"excerpt":{"rendered":"
