Greetings all,
I wish to bridge two Adcom GFA 555 II power amps. Would someone kindly provide a diagram as to how they hook up. Best I follow instructions visually as that, for me, is the safer way to go. Many thanks

all Adcoms I've seen had a picture on back of amp

Sort of, yes. However, do I take the red + from the Adcom pre-amp to one power amp that is set to 'bridged' and the black - line to the other? Think I know how the speakers connect. Scary stuff.

It worked! No sparks, no blown speakers, no area power outages. Sounds fantastic, and a triumph for vintage equipment. This is the line-up: Adcom ACE-555 AC enhancer/protector > Adcom Preamp GFP-555 > Adcom GCD-700 CD player > 2 x Adcom GFA-555 II bridged > 2 x Mordaunt-Short Signifer speakers (circa 1980). Yes, Adcom may have been entry-level audiophile, but for my aging ears and my modest budget, it suits my needs. Now all i have to do is find a way to build another system for my Adcom GFA-555 - newly serviced and ready for action. Why, I even have a pair of Thiels sitting unused. And so it goes...
