Old amp, how many watts by looking at panel?

[jrlouie]

So I acquired this old amp, and the back panel lists specifications oddly. By looking at the back panel and reading its specs, is this two channel amp 175X2?
Or is that 350 watt specification something different, maybe the power source or something because you'll also notice 120 watt spec by the switched outlets.
I don't have a manual for this guy either. That obviously would be the easier way ;)

Thanks for your responses.

You can't tell per channel wattage by the power consumption rating.

Hmm. Okay, thanks.

I did some searching online. I emailed Panasonic (makers of Technics). Haven't heard anything yet.

I may just be out of luck.

With solid state gear, I've found the following simple formula to work very well, in finding 'watts per channel'.

As a general rule, take the power consumption, divide by 2.5, then divide again by the number of channels driven.

For your example -> 350 / 2.5 = 140 140 / 2 = 70 (w cont/ch)

Good to know. I would have guessed it would be around 70 per so that makes sense.

Well, I took the cover off. I found a different model number on a particular component inside. I don't know enough about the workings of an amp to tell you what that component is ;)
But anyway, I searched based upon this new found model number....
SVI 3205
and I found the following thread.

So I guess it is 100W X 2

Thanks for your help anyway!
