huangyong this should help with mounting your heatsinks-----> http://www.melcor.com/thermepx.html

jasonhanjk any op-amp thats single not dual can replace Lm6171 if so how much juice should it be able to handle

could any of these be use in place of LM6171

LM6181

OPA627

AD8610

AD8605

OPA134

AD843

I really wont be able to tell if it only yours till i build this verson on some of the other versions its one the two problems listed. then again you could just have a ground wire thats not soldered good enough.

also i have a question is there an alternative to using the LM6171 other than using caps. just wondering if there was another version or maybe another company made one close to LM6171.

It might. shorter runs are always the best but very hard to do plus it depends on the case you will put the moy in. i'm sure some of the more advance builders here can add to this.

Sounds like RF. do you hear radio stations or any thing other than the music thats playing and this whee sound. other wise it might be oscillation.

Try incressing the cap size to 470uf @25-35volts this may help i'm sure some of the more better builders will have more to add. I myself plan to use 470uf 50volt caps.

Thanks jasonhanjk for the info i have those opa2132's around here so i will use two of them.

Could you use op2132pa op-amps on this pcb?

is there an alernative chip that could be used instead of the LM6171

Since these boards can not be brought with out the use of paypal i guess i will have to try to make my own.

Thanks that however does not show how to conect the interconects. i was looking for a picture of a cmoy's underside with detils of the soldering. the diagram from the listed site you give just tells you where to put what. not what gets solder to what.

Does anyone here have clear pics of how the underside of a Cmoy is soldered?

plan to use an alps pot with built in switch

Is there anyway to order one these pcbs with out using paypal or can the eagle layout be posted to print the pcb's ourselfs.

Also is this pcb for use with the alps-RK0971221Z05 pot
