Roland JC-120 Jazz Chorus Amp Clone

Cool design. Bet it sounds lovely with the jfet front-end.

Let me say though that I would´t recommend +-40V for the LM3886 at all.
Absolute maximum Ratings are +-42V with an Input Signal and the power Dissipation even with 8Ohm Speakers will go through the Roof when pushed a Little.
(see Graphs in the datasheet).
Don´t even think about connecting a 4Ohms Speaker to a LM3886 powered with +-40V. If you´re lucky the device will switch off before max. Junction temperature is reached.

Yes, but just to clarify - the Original JC-120 amp was dual rail 40v, and was not an LM3886 implementation.

My Clone amp - the one in this posting - is an LM3886 for the amp side, with the actual cloned Preamp, and was more like 30vdc dual rail.
