Hi RATs,
Here's a link to a project I've had on the bench for a while and got
finished today. I learned quite a bit on this one.

It sounds as good as it looks.
Comments, questions?
Looks great - as usual

The specs indicate 1.5mV of hum.
In horn speakers with 100dB/W/M that 1.5mV would plainly be audible
if the horns were that sensitive at 100Hz, and the hum was 100Hz hum.
Has any attempt been made to reduce the hum?
