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.

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.

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

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

Plays like a dream.

That, and it's ghostly silent.

Thank you.

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

Best,
