Magnum mc 250

Recommended Posts

Setting bias I have learnt for FET amps is a bit hit or miss.

I load the amp with the current set to zero on the pre-set.

Then a 10KHz signal is plug in so the the 8 Ohm load RESISTOR has just 2 Volts Pk-Pk

You can then clearly see the Cross Over distortion on a scope.

Adjust the pre-set with care until the distortion is gone, keep a careful monitor of the heat sink temperature and it is best a a ambient of 25C

The Amp will sound amazing and run slightly warm and low levels.

I hope this helps?

Best Col

We have done the same thing in the past. Magnum and now it plays nice and smooth. Thanks for the suggestion and if you can get a little more details about this enhancer with which you were in the picture, I would be grateful.

Kasno se javio konstruktor.

Nije me pre interesovalo, ali sam sad sve iscitao, i  proguglao, tako da je ovo po svemu sudeci zavrsni rezultat; evo slike sa komsijskog fifi foruma. Opis u oglasu je, pa da tako kazemo  - neodoljiv!
