Oooo Dm2'sCan't help you with your Quad question Dan but you are in for a treat once you get those DM2's hooked up to somet, as long as the Coles aren't shot that is, in which case they will sound as dull as ditchwater

Hi Dave
The DM2's are sweet as a nut & sound excellent through a denon amp. The quads need a service.

The FM3 is still a reasonable tuner and the 303 isn't bad at all when working properly but I wouldn't bother with the 33 if I were you...Originally Posted by dantheman91

Looks like a 405 to me but hey ho...The FM3 is still a reasonable tuner and the 303 isn't bad at all when working properly but I wouldn't bother with the 33 if I were you...

Hi Dan,
Don't worry about the earth lead on the mains plug for the 405, it isn't needed. The 405 will be earthed via the braiding/screen of the audio lead connecting the 405 to the 33 preamp.
Some people are unhappy with this arrangement and prefer to directly earth the metal work of the 405 (or any other power amp for that matter) directly to the earth pin of the 13A mains plug. In theory this will form an earth loop, but in practice it will cause no problems: I added a supplementary earth wire to the 2-core mains lead connecting my 405 amp to a 44 preamp (whose switched mains outlets were IEC 3-pin types with earth).
PS From the photos you have connected up the units correctly.

Yes it's a 405-1 (with the silver-grey anodised front heat sink).Looks like a 405 to me but hey ho...

Agree with your comment, except the 405-1 can benefit from a very simple and cheap upgrade by simply replacing the LM301 op-amp with a superior type.

I should have quoted Jez, Barry as mine was a response to his post regarding the 33

Ah - but though the 33 preamp design is very much of its time and now sounds dated (as do all preamps of that era, such as the Radford SC22, Leak 'Varislope', Sugden C51 etc.), the Quad 33 is not a bad sounding amp.I should have quoted Jez, Barry as mine was a response to his post regarding the 33
Rather than shell out for a new preamp, I would have the likes of NET or Dada upgrade the Quad 33.
