Default Heathkit amp questions.

I just got one given to me. I wanted to hook it up to some speakers to see if she still worked.

This is for a Model # AA-14 btw.

For the speaker hook up, the left and the right are clearly market, but I don't see anything for + or _. I've never seen anything like it.

If anyone has any knowledge about this amp or the area of speaker hook ups that aren't marked, please let me know. I have some test speakers (I'm not plugging my good stuff into it), but I wanted to try it out. I read some reviews on Heath amps and they got good reviews, but this is not a tube amp It doesn't have a year on it, just a serial number 11241. I tried to google what I needed, but this must be some rare stuff. Google hardly ever fails me, but I couldn't find squat on this amp.

Any info would be great.

Thanks

Default Picture of speaker hook up.

How do you upload a picture? I see the attach file browse button, but then what? It's not uploading a pick.

Hi gvr4ever,
The file has to be less than 100K I think.

Push the browse button and navigate your hard drive the file you want to post. Follow the directions and info messages.

If you are running XP, right click the file to resize to a lower resolution before trying to upload.

I still can't upload the pic. I've edited down to 60kb of space. Also, why can't I edit my own post? I'm making a mess of this thread.

Also, I did learn that my amp is a solid state amp, so this should be moved if a mod happens to come along.

Hi gvr4ever,
A mod came along.

There is a time limit for editing posts. I think it's around 5 min., but don't quote me on that.

I've never heard of that particular amp. Most of the Heathkit models were tube, although they did make some solid state receivers.

Send your picture to bhomester at gmail dot com. I'll try to attach it for you. Send full res if you want.

It appears to be a 20W solid state unit. Schematic can be found here.

Ya, I acually found that, and I understood most of it. I could follow the switches n stuff, but for the speaker output, I'm still lost.

The amp doesn't even have a speaker A-B option, but the back has two hookups and two others that looked bridged or something.

I've never seen anything like it. My 5.1 amp supports two center channels, so you change the way they are hooked up if you have more then one speaker, but I don't understand why this amp just doesn't have 1 positive hookup and one negative hookup. Why all the mess? It doesn't seem to be anything that was once expensive. It's just really confusing. This is the first amp in my life I've seen where I didn't know how to hook it up and it's acually starting to make me a little angry.

Here is a picture of the back panel of gvr4ever's amp.

The "com" marks the "negative" connections. It looks like someone added a jack and covered part of the notation. Otherwise it's pretty clear.
