[Richard Haack]

Hello

Im going to buy 2 of these chips from JBL.

Are there any of you out there who have done this procedure of replacing the bash chips. I have constant hissing now where it used to be periodic.

Help Please Anyone

Thanks

This will be too late for the initial request, but for those who read this later: Strip about 4 inches of insulation off a longer length of 18 or 16-gauge stranded copper wire. twist the wire so it stays together as a single strand. Bend the bare section of wire in half and lay it so that half runs right against each side of the row of HC1011 pins on the bottom of the board. You might use a knife blade perpendicular to the strip to hold the wire in place as you then tin the wire with solder. Keep adding solder along the full length until the pins of the HC1011 chip are touching molten solder, and with a rag gently pull the HC1011 chip free. If there is any resistance, stop and be sure every pin is contacting molten solder. Don't use more than a 60-watt iron so that you don't overheat the board. Then use a desoldering tool (vacuum) to remove the solder from each socket. The new chip will easily drop in place, and the through-the-board sockets will still be in place.
