yes those smp08 are fantastic very fast slew rate the envelopes will be snappier as the sample and hold responde quicker to the transients so it was the 8bit dac for the cv circuit that was at fault there you go just goes to show what 20 years of synth servicing does pay off i was glad to of helped that fix by a repair tech in usa would have cost you $70 per hour also as see your upgrading chips the tlo82 can be upgraded to to tle7072 i have fitted these for the sq80 sq1 eps sampler and the dss1 from the 2448 op amps there clean and have a great headroom with out distrortion they are direct drop ins as they are now the replacement chip for the tloxx series ----- Original Message ----- From: "Preslav Lefterov" <plefterov@...> To: <emax@yahoogroups.com> Sent: Wednesday, February 24, 2010 2:39 PM Subject: Re: [emax] Re: Emax Problem Diagnosis > Just an update: > > After purchasing the AD7524 (link below) from Digikey in the US and > replacing it, my Emax works now.
