I'm parting out an ESQ, and as a result have 7 CEM 3379 filter chips and 4 SSM 2300 analog processor chips for sale. All are tested good. I'm asking $12 each, or less if you buy multiples. Or feel free to make another offer. Also, if anyone is looking for any other ESQ parts (other than the power supply and the CEM 3360) let me know. Thanks, Mark
