Mail address, please.
I have two schematics, but are too big to attach them here.

I thought you already had the Service data and schematics from my site....

http://www.dc-daylight.ltd.uk/Valve-...-and-Info.html

Start from link above and work your way to QUAD 405 also see link to schematics.

Best regards

Keith

Default 405 - 2/1 service data needed

Hi dcd

I've just checked out the link to your Quad 405 mods which I find 'impressive'. As you may have seen elsewhere, I've just started on the long road to make a better 405/1, which I acquired recently (being a Leak Stereo 20 man for the last 20 years or so!).

Work done until now was replacing the binding posts, extending the din socket to two rca's and fitting a small on/off toggle at the second last blank hole right ( I had a slight hum at extreme right and moving it stopped the problem).

And then, I repainted the two side plates and the top colour in auto basecoat/clearcoat metallic grey to make it look 'different'.

The last mods for now would be to replace the old electrolytics and taking a breather to enjoy my handiwork for a while.

I can mail some pics if you'd like to see a 'gris tungstene' 405 as it was paint left over from a previous Renault.

Cheers

bulgin

thanks for the comments - If you are serious about the 405 you really should change the input stage to the non-inverting topology on my web site but of course listen as it is for a while (perhaps with the speaker connections reversed) I would welcome you views if you ever do the changes shown.

I actually have an espace that colour! so I can imaging how it looks did you apply the top coat ?? Rumour has it that QUAD used Rover car colours without the clear coat and over the years I have made some restorations this way which have aged well I guess the aluminium oxides with time and the finish matts and either lightens or darkens depending on the exposure to light.

Do you do your own (Blue) anodising ??

Regards

Keith
