Chinese 50W

According to AliExpress this is a LJM MX40, whatever that is. The letters LJM apperas very often and it is easy to think of the combination JLH - John Linsley Hood - a name known for fantastic British amps some legendary class A transistor amps.

The kits and even RTR boards are available cheaply from various sellers in China. IF the amps works, they are a bargain.

I have gotten mine together but still not gotten the PSUs mounted. Got a pair of suitable transformers and wanted the amps to be monoblocks. Also the same transformers will fit my SymAsym, to which I just ordered PCBs.

The schematic below may be for the MX40, but I am not that sure.
