Hi all I am replacing the Power supply and output caps in my 303 and was wondering which way up they should go. At the moment they have the solder tags up but...
In my experience, eventually, electrolytics do leak and the stuff which creeps out is not that friendly to the interior of an amplifier. BEsides which, it can...
Hi, You can mount them with the solder-tags up. The reason why Quad mounted them with the solder-tags down in early versions was the size of the capacitors in...
Happy new year to all, Am i dim or are the marks on the end cap of every electrolytic capacitor there as a weak spot to ensure that caps fail in one direction...
I collected recently both amplifiers. The heatsinks of the 520 and the cover of both amplifiers were in a bad condition. I discovered that for repainting the...
Hi Joost, Do you increase the overall value of the PSU caps on a 520? Or just leave it as is? I'd not realised there was a 520 preceding the 520F (so I guess I...
Hello Peter, First, the 520 is a good amplifier, I own one, but the subject was: mod suggestions. The 520 is at 405-3 level,lower noise and more power. Quad...
Hello, I have the possibilty to purchase the awarded Acoustic Energy AE1 Signature Speakers. I am the proud owner of Quad IIs amps and I am wondering if...
ELS57s have a sensitivity of around 87/88db. However, it also depends on the current draw of the speakers....... and their impedance. Chris Beeching [Non-text...
EL 57's have an impedance below 1 Ohm for frequencies above 15Khz. You should never drive ESL 57's with anything other than a Quad 303 or a Quad II. I killed...
I recall a local Quad dealer who sold stereo pairs of ESLs with 405s. Gra' ... From: quadhifi@yahoogroups.com [mailto:quadhifi@yahoogroups.com]On Behalf Of...
Like most of us I wanted a Quad in 1974. I worked for Philips in Leuven as a technician for quadrophony. Later I worked for MBLE. After that I worked for...
I see an offer on Internet: what's the difference with respect to standard ESL 63? I mean, both in terms of construction and of sound quality. Thanks Roberto...
The Quad ESL 63 PRO is a studio version of the standard ESL 63. ¡ñ The Professional loudspeaker has side handles for comfortable transportation, though they...
Hello The Pro also has screw threads in the side panels that mean it can be hung from the ceiling. The Pro was originally made specially for Philips recording ...
Boberto, By the way, I'm pleased to tell you that I have "on loan" a pair of 988s which work very in my small room. They are about 3-4 ft. from the wall behind...
From what i understood, the PRO also has the white more open electrostatic panels fitted. Instead of the older black ones. All later models or revised 63's...
Hello Stuart, it's good to know that 988 are OK in a small room. I think also ELS 63 should fit well at this point. I did not abandoned to consider Quad ESLs...
Hello Jeroen Yes you are right about the white panels that have a wider framework thus allowing the sound to be less restricted. I don't have a photo of the...

I think you will find that the GZ34 has a filament draw of about 1.9amps and the GZ32 of 2.0amps at 5 volts. I think that particular difference is immaterial....
On the later 63s the 4 panels are attached to a separate piece of aluminium which is mounted in rubber sockets an the top and bottom plastic castings. I don't...
I have recently become the owner of a QUAD FM2 Tuner which in good physical condition. The only problem, which is pretty big, is that it does not work! When...
Hi Jeroen I do see what you mean about the side panels there are quite a number of differences between the standard and the Pro models. Regards Richard ... ===...
I am in the process of replacing the caps in my Quad II's with Audience Auricaps. The manufacturer states that the black lead is connected to signal path in...
