I think I'm nearly as bad as you: I have two 303s (one modified and fitted with Cannon XLR connectors, a bit like the 303K), the other is standard. But I also have a pair of Quad 50E monoblocks; so four "303-shaped" lumps of amplification.
Good to see you don't pander to the 'hosepipe school' of philosophy when it come to speaker leads!

Nice pics, Ian. Reminds me of a Dub Sound System

I rather like the rough honesty of that cabinet!

Very nice!
hi guys
im using a avi lab series amplifier,people say it can be a sterile sounding thing,but i cant say i find that the case,really like the sound in fact...which brings me to my question...
how would something like these quads or the quad 606,909 compare to the avi,im very tempted to try a quad but i always read mixed views and feelings regarding there sound quality and the prices there fetching these days means i cant take a cheap punt just to try and see....but i confess i certainly love the looks of them...more so the 606 series
hope you guys dont mind me asking in this thread....i just thought while all you quad lovers where in one place i would ask
feel free to delete if im hijacking.
regards

Hello Paul,
I've owned most Quad power amps over the years and found them all faultless though I can't offer a view regarding comparison with AVI gear I'm afraid. I've seen your ad for a 306 and hope that works out, always best to try for yourself. I try to avoid describing sonic qualities these days, but maybe I'd describe the 303 as being like a mellow red wine ! I regret letting my 909 go so that says something.
As for the hijacking thing you mention, don't be daft . I'll talk to anyone anywhere about Quad amps ! I'm sure others may articulate more than me, but you're doing the right thing in trying one out in your system. Cheers.

Hi I have a surplus of Quads at the moment 2 X 303 4 x 405-1 and 2 x405-2 8 x 33 preamps 2 x 44 preamps and 5 x FM4 tuners ( 2 need repairing 2 have the later chip that removes the battery ) most of the 33 preamps have been upgraded to the DADA style 16v power supply and new caps etc . I have yet to get round to 3 of the 33 a these were a trade in for upgraded ones . The 405-1 also need new caps and R7 and R8 feed zener diodes to power the input op-amp. They are underrated for power. They dissipate at least 0.37W and the resistors are 0.25W. So at some point one burns out, puts the op-amp hard to one rail, pegs one dumper at the power rail, the crowbar fires and blows the dumper, the driver and then the crowbar. Then the rail fuse blows. The resistors should be replaced with 1W resistors, spaced away from the board by a few millimetres to allow air to circulate . Electrolytic capacitors associated with the protection circuits are directly above R30 and R31 (560 ohm power resistors). These run hot, and cook the electrolytic. These are ROE epoxy potted caps, and will be badly discoloured and cracked. When replacing, the caps should be soldered to the track side of the board to keep them away from the heat and of course the RIFA caps on the power switch
( the advice on the 405-1 is thanks to Craig Sawyers from the https://www.vintage-radio.net/forum/...569#post986569 )

PS I do like the 303 sound it is very mellow
