OK, but the safety ground should go right to the chassis near the IEC plug.

Measure voltages for us to check.

Default Thought this data would be of interest

I've (only just) started having a play with RMAA and thought I'd throw this amp on for testing. The load was a 4.7R wirewould and ally housed and the terminal on the amp used was the 4 ohm one.

Results below.

and very belated news...

I changed the gnf caps to some mica units and the sound has come alive. I was nonplussed earlier in the process, but she sounds pretty good now.

Critical listening reveals a somewhat tubby bottom end, but a pleasant mid predominates, so in the end I call her a win. Reccomended!
