Thinking about fuses:

Main Fuse: Value? Slow/Fast?

I would like to have fuses on the secondaries too...
0-9Vac: Value? Slow or fast?
0-15Vac: ?
16-0-16Vac: ?

Done some work on the enclosure.

Made crude angles to mount ECC86 horizontally.

Braided internal cable(analog) in silverwire(4x0,6mm).

Done, waiting for 75ohm digital internal cable.

Hi Jonas, Your making good progress. So sorry about your dog.... Always hard to let them go.

I miss my dog too. Time helps. Dave

Thanks Dave.
Yes it was a hard thing to do, but it had to be done.
I still think about Kid my APBT male that passed about 4 years ago.

Yes... I understand, my American Eskimo dog (Mr. Data) has been gone since 2005.... Very Sad to see his picture to this day. He is sorely missed. Same situation. He was suffering from old age problems. Dave

It's the hard part about having dogs, having to say goodbye. I try to remember all the fun times I've had with my dogs, how they were before they got ill.

Hoping for some parts to arrive today.
RCA-connectors, 8mm 75ohm cable for digital signals between my SB and this DAC. 3mm 75ohm cable for internal digital wiring...some more silverwire to braid into two pairs of analog interconnects. And some other small items...

Nope, no parts today.
Another day of waiting...
