Hej alla svenskar, and other Crescendo fans too!

I think you swedish guys should trust the english version of the Crescendo project published in the beginning of 80's.
Bill Cedrum who translated the magazine to swedish (Allt om Elektronik) is not an engineer and used to have a technical flawed language, but he have learned throughout the years.

A note to you all regarding the picture of a Crescendo attached inPost #43, the output resistors (white reactangular) on that picture are wire-wounded, these are idunctive and is a big cause why Crescendo oscillated

Change to 5 x 1 Ohm and 1 watt film-resistors per each wirewounded resistor.

Lycka till!

Ohm's law tell you that.
If the output power is 250W-RMS, and the speaker's impedance is 4ohm, then the RMS current is 7,9A, and the peak current is 11,18A.

Sorry, but if you cannnot calculate it yourself, and you don't know Ohm's law, I dont suggest you to bulid a 250W rated amplifer.

I=U/R and P=I*U
So I=sqrt(P/R)

I=sqrt(250/4)=sqrt(62,5)=7,9A
