Adcom 535L upgrades?
Have you looked inside the amp? Leaking capacitors etc..? Might just need a good cleaning the 535 while the lowest watt was considered one of the best performance for the money at the time. https://www.stereophile.com/solidpoweramps/adcom_gfa-535_power_amplifier/index.html |
The 535i is a well designed amplifier and responds well to upgrades. Do a search and you'll find a good bit of information about upgrade paths. If I remember correctly it was a Nelson Pass design. Here's one: https://hoppesbrain.com/2015/06/12/the-super-high-current-adcom-gfa-535-ii/ There was an outfit that specialized in upgrading 535i but I'm not sure if there are sill in business. Worth checking. |
I’ve owned a few 535s and they always worked flawlessly and sounded fine. I currently use a later 5300 as a backup/satellite (outdoor speakers) amp and sold the last of my 535s a few years ago. The 5300 is 85wpc and in my humble (!) opinion it sounds far better than a 535, even the later models (5 way binding posts added instead of the twisty things they had originally). I may get the 5300 upgraded someday or fixed if the caps get leaky as it just works as it should. Great torroidal/mosfet amps costing very little relative to how they sound. |
