Would anyone know where I could find the output wattage on a sherwoold AI-1110 amp? Im trying to build a set of speakers and i want to use this amp for them but i dont know what the power handling needs to be. Any numbers would be appreciated.
Follow Ups:
List Price in '88-90 was $160 to $220. Rated Power was 50 watts @ channel into 8ohms from 40Hz to 20kHz .
If so, then that's typical. I have a 3 year old Sherwood receiver, and again, the instruction manual did not state output power. I'm guessing that my receiver is about 45-50wpc as my speakers are rated about that themselves. The combo works well and sounds great.FWIW, I am using a pair of vintage early 70's Sansui SP 1700 3 way speakers w/ this unit.

The girl i got it from says its pretty old, i havent been able to find any documentation for it, but now that i play around with it im finding that the 3 (R main and L and R surround) of the 4 channels are not working...is this fixable?
First of all you say that the girl you bought this from says it's "pretty" old? Just how old? Second, the three position switch says surround right? that indicates it's at least late 80's, early 90's vintage. 3rd question (alright, more than a couple of questions :-P) are you using more than a single pair of speakers?If you are using two sets of speakrs (2 pairs), and you aren't getting any surround, what may be happening, assuming it's a simple surround system is that, one, you don't have any music w/ surround channel information (you need that for the surround to work, a movie w/ a surround soundtrack for instance on a Hifi VCR). But if not a *true* surround, you may have what is called surround, but it simply widens the stereo seperation between the existing 2 channel setup. or it's simply not working at all. If you into Home Theater, then it's important, otherwise, don't worry about it. 2 channel is fine for music reproduction anyway.
What a basic dolby surround, assuming that's actually it, is that you get the full frequency range in the front 2 channels, a partial frequency spread-in mono to the two rear surround speakers. This arrangement simply allows the sound to envelope you a bit more. THX and Dolby AC-3 (or 5.1 surround) uses a center, a pair of stereo front speakers, a pair of stereo (or two channels split between both rear speakers) and a center channel speaker. This allows the sound much more realism from dolby surround movie soundtracks.
I think you have either a simple 2 channel stereo "surround" or a simple, earlier 4 channel surround system and w/ a 4 channel surround system, you need two pairs of speakers and surround sound software to take advantage of it.
Hope this helps.

John,
it actually doesnt have a 3 pos switch, its got 2 on/off buttons on the front. One says surround, one says main; main is the primary (front 2 channels). When you press the surround button it engages the second 2 channels. Im pretty sure i figured out why the right channel isnt working (I looked inside the case and found a blown fuse) that was just a quick inspection, i havent gone through to see if that is actually what is causing R not to work. Ok as far as the age of the thing, her exact words were "Its old as he**" to which my reply was "Ill see what i can do!" she didnt know the power ratings on it either, and the only marking on it as far as loads go is to use 8 ohm minimum speakers. As Far as Dolby 5.1....no, if shes right about the age i think they were still working on Dolby 2.0 when this thing was made ;)Right now im only using one speaker to test each channel, a Rockford Fosgate RFZ-1810. (10" subwoofer 8 ohms load w/ 100 watts RMS) (I know this is the ghetto way of doing it but it was the only 8 ohms speaker I have right now!)
Thanx John from Seattle! I confirmed last night that the fuse was blown (whether or not that is the problem with R im not sure yet, well see!) I have to agree with you on the second 2 channels just being a widening factor. Thanx again!
Is my guess. I have a Sherwood, but it's only about 3 years old at the most and it has two sets of speaker outs, but can be switched in either singly or together. Should verify that... :-)But I have a simple on/off push button that simply says surround. All that does is simply widen the stereo spread between the two speakers, making it much wider than normal. Does imphasize the surface noises that may be present on vinyl though...
Anyway, good luck. It may be old enough that it won't take a 4 ohm speaker. Mine does though. But with the power off, I can move a switch from 8 Ohm to 4 Ohm. But I run 8 Ohm speakers so...
Anyway, have fun with it and I hope you can get all working fine.
John.
