I had a similar experience the first time I built my Steimusic Philips CDP.

The cap was on reversed polarity

Now it plays wonderfully.

Yes, it was a learning experience . The cap was on the -10V and he connected it with minus to GND...

Reversed polarity is quite a common mistake.

As my work involves using a PC 12 hours a day, my eyes are not perfect anymore so....

My CD worked for two hours and I always heard a little frying noise that I could not identify... then crack and the cap it started to leak.....
Some cleaning a a new cap solved the problem..

Faraday´s cage to avoid induced electromagnetism right ?

I am thinking I must place the 2x9v TX outside. (Leaving it inside would take the place needed for the future discreet output stage)

I can fasten it to the back plate (outside near the stock TX) and pull the wires in through a hole...

Should I expect any problems from that setup ?

Regards

Ricardo

Another question....

The discreet output can be fed by my 2x18V Nuvotem ?

Did I miss something when programing the mods ?

I am using this TX for the opamps... can I use it in the future for the discreet outputs?

Feeling a bit

Hi Ricardo

The tx mounted externally is fine and yes the opamp feed is fine for the discrete supply.

I did cut the earth loop "acoustica.org.uk" and things god a lot better.

Afet all my experiments, I believe this machine needs two clocks:

One for the DAC to optimyse timing, spatial presentation and overall sound cohesion.

And one for the servo where we get detail, dynamics and insight.

I am saving €€€€ right now

By the way, I love your integrated... I am wondering if the power amp G&W Class A is as good or better.... Do you know this big brother ?
