BatoMM amp.LM-bridge,consider to try it...

We have disquisition on our forum and Macola explained us in details whole problematic behind supply voltage.
In short, it is mistake on current (latest) schematic so just keep proposed values from original schematic to +/-27VDC for 8Ω load.
Other corrections on latest schematic are relevant.
We will correct that in new schematic revision.

I have 2 x LM4780 chips. Would it be possible to use these chips in a similar circuit to the BatoMM????.

Thanks,

Myles

In general yes, LM4780 is almost the sam IC as double LM3886 with slightly less output power.

Unfortunately we did't make PCB for LM4780 configuration.

Current PCB for LM3886 are checked and tested, more than few hundreds PCBs are made and AMP work very very nice.

My Bato-MM finished in a old cassette deck case powered with SMPS. It play very well and is worth every euro you spend on it.
