Musical Fidelity A100 Help Needed

king10 · 26th February 2012, 07:31 PM

I have a A100 in need of an input switch, can anyone help out with a part number and a source? Can it be rebuilt or is a NOS/alternative the only way to go. I saw a site on the web that discusses a Farnell replacement part that with modification can fit but omits a part number.
The original was damaged in a shipping incident. It looks like the box took a hit and the shaft had pushed its way through the blue housing.
I have contacted MF in the UK but have not yet heard back.

The unit is in nice shape and I would like to restore it.

Good place to start is Mark Hennessey's site here:
Musical Fidelity A1
good luck!

Thanks, I have seen his site and find it very informative. Mark describes a alternative to the Lorlin selector but does not give a part number that I can find.

It's possibly a bit late to reply to this thread now....
However I have successfully replaced the input selector switch on my A100 with: RS Stock No.352-288

I did exactly as Mark Hennessey suggested here: Musical Fidelity A1 - Mods

Although my efforts are nowhere near as neat.
You really should build his replacement pre-amp as well.

Cheers.
