Hello Quad folks I have two different versions of Quad 66 pre. A Mk1 before serialnumber 210600, and a Mk2 over that serialnr. I know the two versions have...
This input was intended for a external remote control sensor, used in multiroom systems. This external sensor was never developed. Stefaan Verdonckt ...
Hi Stefaan Thanks for your answer. I knew Quad never developed anything useful for that purpose, but is it possible to connect other equipment/external sensors...
Hi, It should be possible to make an external IR-sensor but the problem is I don't have the schematic for the 66. If someone has the schematic or the...
Hello Jeroen Yes, there is a bas step on both mk1 and mk2, they are identical. They are called S1 and S2. There are two filters, F1 and F2. Both Step and...
Currently driving 57s with a Quad 306 (with 34/FM4) and it works extremely well. I've also tried a Cambridge 840A which also sounds superb and is stable but...
Hi Rob, What sort of speaker cable are you refering to? I'm running an ... Max Adelman 07768 656 996 020 8761 3307 [Non-text portions of this message have been...
I am a new member & this is my first post. I have Quad 44 serial number 32387, which is I believe a late one. I had the 44 & my 405-2 serviced by Quad. The...
Hi Max, I use World Designs SQC which is just simple figure 8 cable. Good quality and inexpensive. For a belt and braces approach Naim NACA5 works well as it...
Icaras, a couple of things suggest themselves as possible reasons. Its many years since I used a 44 but I believe that the radio input card presents a much...
Nice little extra earner more like (but what's in a Naim :-) I'm more inclined to believe that inductance differences between straight laid cables are...
"Amazing what one reads about speaker cables but I trust those who sell well spaced and adequate copper within good insulation." Yes, 15 amp solid core mains...
Hello Robert I think Icaras did the right thing by swapping the modules, the problem is "behind the modules". So the 4066 switches are suspect as Stefaan...
Hi Stefan Thanks for the reply. I believe there are 4 4066 ics, do I replace all of them ?? Which is the best 4066 chip to replace with ?? Thanks Icarus...
Hi, Icarus, If you replace the faulty chip it is good practice to replace all 4 of them. Anyway the cost is 78 Eurocent each (see Ebay-object 390002401611). It...
Stefaan Thanks for your advise. One more question... Whilst inside the 44 I may as well replace the aging OPAs, question is what to use ?? My 405-2 I have used...
Very true - these days I usually recommend something like 79 strand which is cheap and does the job...... however...... If you suspect that your amp is on the...
It's surely more an issue of gastric revolt than technical merit :-) It's surely resistance (and capacitance) according to length that count most. At audio...
Hi, In the 44 the OPA604 / OPA2604 is the best choice as the power-supply rails are + and - 15 Volt and we are around a 1 Volt signal. For the Disc-board you...
Is it a real CD/AUX input (300mV) or the old 500mV AUX card? If it's the latter you need to get a CD/AUX module from Quad. The old AUX input does indeed sound...
ejp286 Yes it is a 'real' CD/AUX input. It sounded great before I made the mistake of having Quad 'service' it. Waste of a lot of money !! Thanks all for your...
I wouldn't: I doubt that the 4066s have anything to do with it. I would check what Quad have done to the CD/AUX and if necessary put it back the way it was....
"and use low capacitance/high-ish inductance speaker cable and all should be well." Please excuse my ignorance but, Ummm - how do you identify capacitance and...
Several parameters matter (or don't) for loudspeaker-cable: * The resistance in Ohm per Kilometer. Normal 2,5mm copper-wire has a resistance of 7 Ohm per...
Hi Again, Just in case anyone is interested in the continuation of my saga about matching paints for the Garrard 401, which I have now brought to a sucessful...
