Hi there, I am currentlly ripping apart a Rogers A100 class A 55 watt per channel amplifier to use it's power amp sections as monoblocks. I will be using a seperate power supply for each that should help boost the wattage and it's ability. It uses some form of current dumping so runs nice and cool when quiet.

I was wondering if anyone had any information on the Rogers A100, about it's designs etc.

Default Dividing Amplifers

What a great project. . .I've though about doing something
similar to a Rotel amplifier. Mount each half on the back of each
loudspeaker. . . someday.

I have lost one of the knobs for my Rodgers A100 and wondered if you are breaking the amp if I could buy one from you?

ClassA .... &.... runs nice and cool
does not equate.
Is it ClassAB?
Do you have a circuit/schematic?
Do you intend fitting bigger heatsinks?

I've just picked up 2 of these A100 amps, both with wrecked power amp sections.

Does anyone have a copy of a schematic/circuit diagram?

Just about the only integrated i'm aware of that uses the amp's back panel as a heatsink.

2 Motorola TO3 output devices per channel, about 5 watts in Class A would be more truthfull.
