Quick update. The left channel comes in when the volume is turned up enough - just overr 2 for CD. I did notice today that there is a fizzing sound in the left speaker - with everything off apart from the 405. I need to check again, but I'm sure I've heard it before.
The 33 does have a sweet spot on the volume pot - just over 2 (at least mine does). You listen to your stuff quietly, like me :)
I'm using a pair of Primalsea's -14db inline-RCA attenuators on the CD input. This lets me wind the volume up a bit on the 33, and gives me more control at lower levels. You might want to PM Paul (Primalsea) and see if he's got any these left. They're about the size of an RCA plug gender changer, and go between the end of the RCA from your CDP into your pre-amp RCA sockets (or DIN to Phono sockets).
The fizzing... not sure what that is. Does it happen with all the inputs to the 405 unplugged?
Ah, cool. I thought it might just be a quirk of the gear. And, yes, just over two is where the proper sound kicks in.
I need to fiddle/listen a bit more to work out what is happening with the fizzing sound.
Unfortunately, the Quad 33 volume control does not have very good balance at lower settings. There is often slop in the linkage of the two channels. This is made even worse if the input to the 33 is a bit high, say from a CD player or tuner (other than Quad tuners that have a low output).
Come on guys, this is obviously a dirty volume control. Clean it with some switch cleaner and live in harmony for another 25 years!! :kiss:

Hi Peter
The volume control has a small slider that moves over a carbon track. This will wear and get dirty. Especially where it has been used the most often. You may get away with cleaning it by squirting into the edge of the control (you should be able to see the slider rotating it you look sideways into it whilst moving the knob). Or if it has finally worn out, it will need replacing.
You can get this from CPC or eBay http://cpc.farnell.com/servisol/1000...equestid=46980 :kiss:
If you are struggling to understand this, then you need to leave it to an expert. But make sure the expert really is an expert first!!

Is it possible to make my own switch cleaner? If yes, what with?
Thanks
Peter
No
Fair enough.:cool:
Stupid question. Is Switch Cleaner ok for potentiometers (volume controls)? I seem to recall reading somewhere that the carbon tracks on pots could be dissolved really easily by some switch cleaners, and that a special cleaner was needed for them :confused:
