| Volume pot issue |

Good luck Bender. You might want to get some 2 conductor shielded cable to run between the board and the new pot. The shield will attach to the grounded pad on the board, and it will be the third conductor. It will prevent any interference (noise) from getting into the wires. If the pot is very far from the board, it might be a necessity to run shielded wires. |

Look, leave that poor 60-in-1 PCB alone. There is an better way. I've got a pot here in front of me from an arcade cab with relatively good speakers (for an old cab - it came out of a Mortal Kombat cab), designed for use with "normal PCBs" (MK have a special secondary sound board), with modest-good volume amps built in. It is only a 50 ohm pot (NOT 50K or 50 kilo-ohm) pot. I'm not sure of the wattage rating, but it says on the pot: "G2 50R AW 1RH". The cab only had one speaker (no more than about 8 watts) and a little subwoofer. I'm been running a 48-in-1 in a cab with a similar volume control myself. It is in a staff work amenities room and is on everyday. Works wonderfully. Soooo .... in this PCB case, I recommend that you go with something like that before hacking your board. |

| Zebidee:
no, just suggesting that you buy a 50 ohm pot similar to the one I described. Ask about it at your local Radio Shack / Jaycar / Dick Smith or other hobby electronics store. |
