anway, you shoud use the wire to make an inductor, it isnt that hard you know..?

Default Inductor/resistoEplxpanation from G.Randy Slone

Per Slone's book capacitive loads from the speaker or speaker wires could cause phase shifting or OPS overloads. The inductor provides protection. The resistor, in turn, dampens ringing associated with the above.

I do not have enough knowledge to to agree or disagree. I'm just passing it on in case the statement is helpful.

I remember one problem I had sometime ago.
I've made a LM12 Amplifier and it get very hot, even with no signal. I've thougt even the LM12 was dead... more than 50 Euro in the garbage... But no. It's only high frequency oscillations and I couldn't hear. After installing 20 turns of wire upon a resistor, the LM12 only get's hot when I reach the max power. And the heatsink was little (10x10x3).
Want to know some? IT STILL WORKS!!!
The conclusion is: use the inductor and the resistor.

Use the capacitor and resistor for zobel network between output and gnd.

I use a 10Ohm in series with a 100nF capacitor and put them in the output terminals of the amplifier.
I think this is better than putting them in the PCB of the amplifier.
Anyone shares this idea?
