Forum : DIY projects : Ask or offer advice on Quad hifi DIY / refurbishment projects http://www.hifi-forums.co.uk/ I have 3 Quad 303s two of which I did some mods on about 4 years ago. The other one I left as a reference for comparison.One of the Quad mod articles I read back then suggested replacing the Rectifier diodes with Schottkys. I did this and it seems OK.It has been suggested to me that I should have replaced the old ceramic plate capacitor which Quad put across the transformer outputs and there may be some other components I should have added into circuit, to cope with the special characteristics of Schottkys as opposed to the original Quad diodes but I don't know what these should be. Anyone have any suggestions? http://www.hifi-forums.co.uk/messages.cfm?messageid=ED09A477-3048-8D61-F80C0A8D72425814&r=1 2007-10-29T18:32:53--01:00 Quad 303 mods question I saw an article about improving the CD transport on a Quad 67. Is there a similar mod for the 66? http://www.hifi-forums.co.uk/messages.cfm?messageid=1491297D-5070-B652-0438B45A7A974FC5&r=2 2007-04-21T14:34:56--01:00 Quad 66 CD Player - Mods
