Hi All,

I thinking of selling my Quad 405 Mono Blocks. These have been upgraded with four F&T 22,000 power supply capacitors, four 35 amp bridge rectifiers one per rail. RCA Phono connectors and power switch fitted.
There is one 405 mk2 board in each case(last revision), which is up to Keith Snook's Mod 3 level. Including 20A output transistors, PRP 1% resistors through out with Z-foils in key areas, OPA604AP Op-amps, new inductors, transistors polystyrene small value caps and Elna Cerefine capacitors. Limiters have been removed and Vellaman K4700 loudspeaker protection boards fitted.

Any interest please pm.

If no interest I'll rebuild them into two stereo amps and slap them on Ebay

Duncan


Happy Days
