Hi,
I believe I did put up a thread on this but perhaps not on serialnumbers and at least the first 75 BJF LGW's came with LF353.
All LGW's, including the MP version, that btw is made just like the last BJF LGW's have a socket.
LF353 is a National Semiconductor chip and would be available from any electronic supply.
This chip combines a few things like low noise, low distortion and due to the construction of the input stge and the outputstage, actually the mere simplicity of those make for low distortion and ability to take temporary overload.
Have fun
BJ
