Hey everyone, I bought this Fisher CA-120 Integrated amp the other day, and i cant find any info ANYWHERE for it. I wanted to know Wpc, Wpc RMS, THD, and signal-to-noise ratio. It sounds better than my pioneer sx-450, and i figured it was more powerful (it would almost have to be, the pioneer has 15Wpc).

I appreciate any help you have:music:, thanks.

by the way it has meters for the left and right channel which has two things dB meter and a watts/8 ohm meter. The watts/8ohm meter goes up to thirty which if you take 30 * 8 = 240 watts... obviously that cant be right, can it? Anybody know what the watts/8Ohm thing means?
 
I've got one right in front of me I just fixed last night.

It uses a amplifier IC. Compact chip. A big one though. It's an STK465.

rated at 30 wpc rms @ 8 ohms. Not bad intermod and not too bad thd.

The meters are what make it cool.

The way you deduce wattage is. V x V devide by ohms.

28 volts into an 8 ohm load is 100 watts. give or take.
15.5 volts is 30 watts into an 8 ohm load, now this is theroretical. Resistive load, impedance changes in a speaker with regard to hz.
I have the matching tuner. It's not bad.
 
thanks donkey, it seems like a pretty clean sound, i think it sounds quite good. Still would like to know the signal to noise ratio, too.
 
Donkey you seem to be a plethora of information:thmbsp:, but either the link you sent me was a bad link or i don't know how to use it. Can you help me?
