Hi there,

Has anybody any infor on FM Acoustics amplifiers or pre.

Very interested in their technologies. Schematic will be even

better.

Greatly appreciated.

If you read through their website, you will see that they do extensive matching, measuring testing to their equipment before they are sold.
Besides they make their own transistors(!), and I especially like their look upon powersupplies - uF is not important, series resistance is!

I guess you can call it like a swiss clock manufacturer.
A schemaitc will give you an idea of the topology, but many of the above mentioned details are the reason for the high price, and rightly so.

I once did some reverse engineering from some pictures - it might have errors, but check it out:

Can anyone identify this heatsink, model and manufacturer?
The T-profiles are mounted in a slot in the heatsink.
Thanks

unbelievably unlikely that they own a silicon foundry... almost zip.

I have been looking at this design. FM acoustics uses two unusual diodes in the ccs. The color rings are orange, brown and yellow = 314 = 1N314. This is an gold diffusion germanium diode made by BKC International. What is the purpose of using this diode?

The other diodes are 1N4148 used in an other position.
