I did a google once and found one place that sent a copy to me for $17 plus shipping.

I am sorry I cannot scan it for you.... too flimsey to do so and my scanner is a pain to use...

If you have some question, I can look at it and let you know.... if not I'd suggest you order one from them:

Hi K-amps,

I see this post dor poa2800 and, you have the schema for it. could you please, check mosfets on amp pcb what numbers are and which p and which is n channel.. I have receive this amp without many transistores on it and, I am reconstructing it. as well zener diode on amp pcb -- can't remember number now..
Of course, if you have time to do this for me, I will appreciate it.
I try to buy online, but none of this sites will accept wire transfer - my only way to pay them.

thanks

The sites accept credit cards.
