Buzzin' 250

Posted by: Chris L on 27 October 2001

Hi all,

Just a quick question. Came down to the living room this morning, and noticed my 250 was buzzing (not through the speakers, but from inside the case). Anyway, being a less than careful sort, I stuck on some music, and had my breakfast - by the end of that size of the LP, the buzzing had stopped.

So, it seems okay now, but I wanted to ask: has anyone else had this? Is it something I should worry about, or is it, as I suspect, just filthy mains supply, while the kettles are going on in my area?

Ta,

Chris L

I send my 135s for a service, and now the fans hardly come on at all, even at long high volume sessions.

Naim adjusted the temperature sensor, which was causing the fans to come on too soon.

I found that my 250 used to thermally cut out when pressed to hard.

Try "RND Technologies - Ultrafilter - Gaetek remixes" on very loud to drive your amp to dispair!

I have had a lot of this in the past, and with multiple amps it can be quite a pain.

A pleasant side-effect of upgading to non-ferous amps has been the almost complete disappearance of buzz.

Nice.

Strange, this is first time it's happened that I've noticed.

Ah well, thanks for the reassurances - let the music continue!

Well spotted.

Martin actually meant non-ferrous supports for the amps.

cheers, Martin

Martin's comment had me searching his profile for DNM gear.
