Perfect amp for Martin Logan ESLs - Beautiful Sanders Innersound Kaya amp. Very good condition. These were manufactured by CODA
So I have found a way to use this Bass Amp full range, with a Volume Control - like an integrated amp, but with only single input.
So I initially asked Roger if this amp was able to be run full range. He said there was a daughterboard that could be swapped between the existing Bass Amp daughterboard (with active crossover network) and full range... He instructed me to email Doug Dale at Coda to see if there are any Daughterboards left for the conversion to full range. He said he no longer had any. I asked if I could have the schematics of the Daughterboard and he indicated they moved twice and no longer had them either...so after poking around on the sockets I figured out two jumpers are needed to make the unit run full range with the volume control. I emailed Roger and he said I got it right....
So the unit can be run full range with Volume control or the daughterboard can be replaced and run as initially intended - as a bass amp and crossover to another amp for the ESL panels...
Only issue is after disconnecting power, the volume returns to zero (does this on Bass and full range - it was designed this way). Roger said just leave it plugged in and running as it only eats a few watts when not driving speakers.
Also have the Remote that is used for volume control.
Highly recommend an audition to see what you are getting. West Sub of Chicago.
$2200 - really don't want to ship this...but possible. Also have a pair of CLS II for sale - could possibly do a package deal for both.
