In a message dated 5/1/2004 7:24:35 AM GMT Daylight Time, ... The Edicron site is not helpful. I know for a fact that the Golden Dragon KT66 Retro is an exact...
I guess you all are fed up with this subject...Sorry about that. I would like to replace the cathode bypass caps in my Quad II amps : Chris reported about very...
I've been running both the Watford Valves (rebadged Russian KT66) and the Golden Dragon retro KT66. In my opinion the internals of the Russian manufactured...
I'll second what Chris says. I did a lot of research into which current production KT66s to use in my IIs before deciding on the Golden Dragon KT66 Retros. In...
Hi Joseph! Where do you live? I have two Ansar polypropylene 25uF 400v caps which you can have for free if you want - I don't need them any more. I also have a...
I have used Saratov KT66 with good results. Bought them from Gintaras on eBay. In comparision with the GEC KT66, the Saratovs has some more slam in the bass,...
Hi all, I recently purchased an offcut of an approved bass diapragm film, 12 micron 'Melinex S'. Even an offcut was 400m long! It works well. In the unlikely...
Hi everyone! I've been busy rebuilding the driver boards on my Quad 303. The original capacitor - C106 in circuit - is rated 47uF 63v. I have two black gates...
HI Chris 'And I think I might worry about a warm (or even remotely hot) choke..... I think someone posted a concern here a few days ago.' I read the above with...
Hi guys Well i am not an expert i have tinkered around and built a few things....but this thing with chokes running hot your right it should be a concern. I...
Hi Rajav y todos I just re-read that email again that first capacitor is way way way way too high...its causing the GZ34 to drawn too much current it will burn...
HI STEVEN Thank you for your letter.I WILL change the filter caps back to speck.Though I have about six GEC KT66 valves which test above average, I am able...
First filter cap should be no more than 32 mF. If not, as others have said, you fry the rectifier (which should be a GZ32!!) and make the mains TX work harder...
My Quad IIs chokes have always run hotter than the power transformer, I assumed that was normal, is it not? Hot enough to touch, but a little bit to hot to be...

Hello, all - I have a simple question, maybe even foolish. I have an even dozen GEC KT66 tubes from a number of QUAD II amps I now own. I have always tested...
Hello, all - What are the differences between the screened & non-screened Mullard EF86's for use in the QUAD pieces? Also, what type of sonic changes can I...
But in reality this is a bit over optimistic. Lee ... From: reylon2000 QUAD II specs allow for mismatching of up to 25%. [Non-text portions of this message...
Measure the voltage on top and bottom of the cap to ground. According to the schematic, there's 33V behind the choke L100. Can't be that much, 67V-33V = 34V...
Hi Rajiv see how it goes but i am not sure that the 6l6gc have a high enough plate dissipation for running in a Quad II, try to get some KT66 Retros, they do...
Hi Tom, If you do the sums, 10000uF is adequate for 2 x100W into 8 Ohms at nominal mains voltage (this is why you have all those voltage taps on the earlier...
Im afraid it doesn;t work quite like that, its the total capacitance that matters irrespective of how its made up i,e 10 x 1000uF elnas, black gates etc...
SJ, Thanks. I was talking about device dependent advantages rather than the actual capacitance value. Looks like interesting reading. Should keep me busy for...
