Here’s an awesome amp I just finished for a customer in NYC. This was really fun to build! He wanted a high-current version of the GFA-545, so we went all-out with dual Avel 500VA transformers, gigantic 27,000uF filter caps, and a truly dual-mono layout throughout. This amp has dual power cords, fuses and power switches.
The sound is just incredible! Perhaps the best one yet. Super clean and powerful, and never seems runs out of gas, right up to clipping. I’d say it has an effortless sound to it. I measured 162W at 8 ohm and 272 at 4 ohm just before clipping! That’s only 50W short of a perfect doubling of power at half impedance. That is one stiff power supply!

Folks, here’s another ADCOM GFA-535 II for sale! This one is in MINT condition. Not a scratch on it, and I’ve installed a freshly powder-coated top cover! It’s gorgeous. If you love the Adcom GFA-535, this is the one for you.
As with all the amps I sell, this unit has been completely torn down, rebuilt, refurbished, and obsessed over. This amp not only sounds better than new, but I intend it to last another 30 years or more! I go way beyond a simple re-cap. Any and all parts that may potentially deteriorate have been replaced, and I’ve paid a lot more attention to detail than the factory with things like wiring and matching components. Every component is checked, and every solder joint shines.
And this one has a little special something. A powder coated top cover! (I got a deal on getting a bunch of covers done.)
