QUAD 77 amps & cd player mods

[Wakefield Turntables]

Has anyone seen any decent webpages with mods/upgrades for the Quad 77 poweramps/cd player? I've seen the quad blog page and also fidelity audio but does anything else exist??

Zero Gain as was had some 77 amp mods I remember, but don't know if these pages still exist somewhere. The preamp could be tweaked a bit, but I have no idea on the CD player.
