Default Musical Fidelity A100 - convert to power amp?


I have a Musical Fidelity A100 integrated amp with a input switch that needs replacing (sounds like dirty contacts in the switching mechanism). Id like to convert the unit into a power amplifier if I could figure a way to short the CD input (or any other line level input) straight through to the amp section. I'm fearless with a soldering iron, but I lack the confidence when it comes reading the schematic. I'd very much appreciate any tips.

I've studied the schematic supplied by Musical Fidelity A1

Could I kindly ask the community for some advice here can this operation be done?

Sure it can be done! But that integrated amp looks very good. I would "fix" that input selector or change it. also I would change those old electrolytic capacitors. That is a very nice integrated amplifier for sure.

Indeed - I'm looking forward to replacing capacitors and loving it up in every way I can. I enjoyed several months of glorious sound before the input selector died. I use the preamp in my tubeDAC and think there would be no advantage to keep the A100 preamplifier in the signal path. I have no need for anything but a poweramp function from this unit. I imagined that a careful solder job would do the trick - if I knew where to point the thing!
