Röhren und Hören

I've been trying quite a few things, but nothing works out well. Always more or less hum or whiz or both. The only radical solutions I can see are: 1)Trenn-Übertrager. 2)A "Ground lift": letting the entire inner PCB etc. float isolated from the metal casing (Is that what Cayin did with the...

You must be the fastest answer-shooter in the country...
(I understand that fancy hat now)

O.K. I'll play around!
Will have no time before sunday eve/monday as I'm on the road.

Schönes Wochenende,

Hallo Erzkanzler, so you still think it must be possible to get rid of the hum as well in this way? If I understand rightly I wire up the extra earth wire as suggested before to any point on the pcb shield anywhere in the whole CDP (instead of to the RCA) until I get the best result? Is it possible ...

Hallo again, rereading the two German quotes the second "extra wire connection" suggestion doesn't seem to fit with the the first quoted diagnosis, or does it? The suggested solution would make more sense in connection with "Erdungspotentialunterschiede" between Amp and CDP... I ...

Hallo, I tried the extra wire connection suggested by Erzkanzler in a small check this morning. Result: Whiz (all drive-unit-motor sounds) is gone. Hum is still there. (maybe even a little louder...) Well that's half the problem gone already; great tip! Somewhere I read about Hum: Aus dem Kreis &quo...

O.K.

it will be done.

thanks to Tom, too...

Hallo Erzkanzler, thanks for your fast feedback and proposals. Really this is very nice and much appreciated! Unfortunately I did not read your last posting yesterday night. But I did some more systematic tests yesterday night and the outcome is interesting: Both Whiz and Hum are the same problem! I...

Hallo Erzkanzler, -Link to photo: It is on this website already. Posted by Perka on the Opera Consonance 2.3 thread on page 15 on 02-06-2005. He says the photos are the 2.2mk3, however this is definetely the CD120-10 anniversary model like I have. You can see the XLR symmetrical outputs are missing....

Hallo Erzkanzler, thanks for your reply. (you comments were one of the reasons I bought the Aurum Cantus!). HUM: I have had the cd unit open already. The earth wire is just like on foto's on the web connecting the mains input plug to a bolt attached on top of the big right sided print board... I'm s...

Hallo everybody. I'm new here. At least as for putting a question. I've been reading a lot here before! I will not write German as it is full of mistakes but I can understand and read it perfectly well! I live in Freiburg at the moment. So, I just got a new Consonance CD 120-10 last week. A China mo...
