Hello Everyone

What I have here is the amp and tuner system. It was being thrown out
(found out in the rain). I would like to know what the rating of the AMP is.
I tried to find the in formation on the internet and came up with nothing.

Thank you,
Jeff

if, as one source indicates, the DC "rails" are +/- 55 volts you can
estimate the max possable power:
110V peak to peak is 55 volts peak
devide by sq rt 2 = 38.5 Vrms

P= E squared / R where R is a nominal 8 ohms

i make it 185 Watts rms per ch into 8 ohms. realisticly it will be less then
that.

Is it a DSP-A500?

No. This unit is from the 80's I believe.
It just reads Yamaha model # A-500.

I guess I will just take it apart and look up the specs on the parts.
