This is the most music I've had in my room…ever 😀 It’s ridiculously good. More of the music has been let out of Richard’s boards and the results certain...

More mods: I've redrawn the power supplies in a better format, as done by Rod Elliot, put the 10000uF slit foil Supertech caps on the input and driver stage supply and put a symmetrical RC filter across the output of the output stage supply because a different solid-state bloke on the internet sez. ...
