MAC MOD 405
USA
Type : Solid-State
1980 onwards
The respected audio designer Steve McCormack (USA) soon realized that the basic concept of the Quad 405 ("Current-Dumping") was great, but the idea was destroyed by crummy parts and a drastic protection circuitry. In consequence he offered a modification kit for the 405. The ultimate Mac Mod were mono amps. The modification contained the following changes :
· Current Limiting removed
· Improved IC fitted (LM 318)
· Faster Drivers ( Motorola MJE 15031 )
· Faster Output Devices ( Motorola 2N3773 )
· Improved Resistors (metal-film 1% by Resista Mk3 or Corning RN-60 )
· Improved Capacitors (Wonder Caps, Wima, dipped mica)
· Improved Wiring (Audioquest) and Plugs (Tiffany)
The Mac Mod 405 surpasses the original 405 in every respect : It was a great sounding amp which could compete with the most advanced high end amps in these days. Harry Pearson of the "Absolute Sound" magazine wrote an enthusiastic review about it. I still regard it a pity that Quad-UK did not overtake the Mac Mod as standard, because the improved 405 is an exceptional amplifier. The only caveat about the complete Mac Mod is, that the ultimate version (= mono amps) has too much power for the delicate ESL-57 (protection circuitry mandatory !), though power output is quite right for the ESL-63.
Special version of quad's 405 Macmod (the monoblock).
