Upgrade Your Quad 405 / 405-2 / 405-ii Power Amplifier Quad 405 Restoration & Upgrade Kits - You send us your amp and we'll upgrade it with our fantastic upgrade kit.The vintage Quad 405 is still a great sounding amplifier, combining the very best of Quads' legendary design skills and build quality. As with all old hi-fi though, the capacitors inside the Quad 405 will be getting pretty long in the tooth. Electrolytic capacitors really only have a lifespan of around ten - fifteen years, after which the electrolyte dries out, the esr goes up, and the all important sound quality goes down. This degredation in sound quality is so slow and steady, that the owner may not notice the change until it reaches a critical level. Simply replacing the electrolytic capacitors will rejuvenate your Quad 405. In fact, using todays high-quality components, your Quad 405 should sound better than it did when it left the factory, and more than capable of showing many modern amplifiers a thing or two!Here at Diy Hi-Fi, we are firm believers in component quality. Yes you can fit standard parts, and yes your amp will sound good, back to its old self, but why not use modern, Audio-Grade components which are made for the job in hand? We have spent many hours evaluating and selecting the finest sounding parts, and feel we now provide best cost/performance ratio for each kit. Using Audio-Grade components will allow the Quad 405 to sound better than ever, with increased levels of detail, lower levels of noise whilst still retaining the classic 405 character.Larger capacitance Audio-grade F&T Cap Low-ESR/ESL power supply smoothing capacitorsNichicon Muse Audio-Grade signal path capacitorsRubycon ZA & Panasonic FC low-esr & Elna Silmic II capacitors usedLME49710 National Semi OpampsFull Bench-Test + 48 Hour Burn-in period Additional Opamp decoupling capacitors for lower power supply noiseOpamp supply voltage increased improving dynamic rangeNew capacitor clipsHigh Quality 30A binding postsRCA SocketsKimber Kable for input signal wiring Price includes fitting of all components and full testing.

I can hear far more detail than before (the upgrade), there are instruments in the background that before were just background noise. All in all a fantastic job. Mike - Audiolab 8000a with phono stage upgrade.My amps are much better now, much more detail and a more powerful presentation. Vinyl from my Moving Coil in particular is much more enjoyable now.
