Were those sitting on the doc of the Bay? (from e ba y)?.
I bought some from there, and i like em!.
I love the output devices spacing, (on a 35cm sink).
Puts your input and outputs close to rear panel too.
You can tell Papa designed them:D.

Indeed they were. Took about a month to get to South Africa, but worth the wait.

I have an order in for most of the components, so hope to get started on them soon.

DC offset is under 1mV on both channels. :cool:

At full bias (0.59V) DC oscillates within 1mV. :cool:

AC ripple/noise on both channels is under 1mV with input RCAs shorted. :cool:

Plays like a dream. :cool:

That, and it's ghostly silent. :cool:

Thank you. :cool:

Heat sinks aren't big enough at all. Get to over 55 degrees C real quick at full bias. Busy shopping around for bigger ones at the moment.

Temp will not rise that much if the fins are free and vertical for air convection
