Hi Again!
Ya know, it's been a long day, lol....I just looked at the site again and my speaker will work....AND I found under the magnifier that the speaker is marked with a plus and minus sign.....heh....
Well, thanks! If anyone can give me some coaching or point me to my next project, feel free!

hi Annie,
The polarity marking on the speaker is to indicate which way the speaker cone will move when a signal is applied.
Assume you connected a small battery to the terminals of the speaker, say, the cone moves foward,
reverse the battery and the cone moves backward.
The need to know this is, if you have a stereo speaker system you would want the speaker cones to be moving in the same direction when a signal is applied, if not, you would get sound 'cancellation' which would effect the sound quality.
In a mono system it dosn't matter, unless you are using a speaker 'column' ie: two or more speakers connected in parallel or series.
In parallel all the '+' on the same line, like wise all the '-' on the same line.
In series, '+' on one speaker to the '-' on the next, ... '+'.... like connecting batteries in series.
The circuit designer says he uses a 16ohm speaker, your 8ohm should be OK.
You may need to increase the 220uF to say 470uF, if you like a 'basey' guitar.
Welcome to the forum, I hung back on saying 'hello' didn't want to get trampled in the stampede!
Hope this helps.
