Here for sale is my Quad 405 Mono Blocks.All the work done on these was carried out by Duncan (Tubehunter).Rebuilt to exactly the same spec as his, 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, 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.
The cases are a bit tatty but could easily be resprayed if you are fussy.
Not looking to profit on these just recoup expense.
If you need anymore info feel free to pm.
