Antonio - I just read your other stuff - those boxes look beautiful.
Please let us know how the machine sounds with wood cases.
That's very interesting to me.

Default Another note for the record

Earlier in this thread, I noted that I had added smt organic polymer decoupling caps (ESRD Series 7.3 x 4.3 mm 16 V 8.2 uF Polymer Aluminum Electrolytic ) directly to the 14 pins of the TDA. I had added these without removing the stock caps supplied by Arcam.

While chasing down a different issue, I removed the stock caps leaving only the SMT caps. Oh my goodness! Very strong positive move. Another layer of clarity is exposed. Started with the Tantalum. Clear change for the better. Out came the needle nose pliers and MKP extraction took about 1 minute. Anyone following the SMT cap on pin approach... do yourself a big favour and remove the stock caps and dispatch them to the dust bin.

BTW, I am picking up an Arcam Black Box Dac in a few days. Kind of for the nostalgia value since I have had so much fun abusing this alpha. One appeared for sale in my area and I have claimed it. Now continue on the look out for any thrift shop special that has the S1 or 2 chip.

Oh my, life's been hectic with a new job, career, change of location, car and other things. The hi-fi has well and truly taken a back seat.

Now, however, I'm settling down again and had a look in my old Arcam to address the disc stopping when warmed up problem.

I took a little video for fun, but it doesn't show much!

Is it definitely not a mechanical issue?

I've seen problems with those disc clamps before and it can sometimes help to only have one of the springs attached that pull the top flap down.
