heathkits were/are just that, kits. User built, came with build assembly manual and operation manual. Usually lost in shuffle. Unless there's a heathkit forum/archive , manuals probably scarce as hens teeth. best go to ebay and see if anything turns up, or maybe some AK soul knows of that specific model. Good luck. Try a google search.

Did you just get this off Atlanta Craigslist? There was one for sale recently.

No. I just get it in a 2nd hand audio shop near my place.

My AA-22 have been mod for pre-amp function with 4 gold plated jacks. You can find them in the rear.

Now i would like to upgrade something. So I need her schem.
 
After 3 months, I can say some my opinions about SS amp heathkit AA-22.

My AA-22 have been replaced transistors. Now left channel is drived by 2xIR (pic1). Right channel is drived by 2xMullard (Pic2). So Right channel is a little stronger.

I have found this amp having so good sound field, transparent, clean. Type of music have played back with the best is jazz. It is good for 3 ranges. The midrange is a little weaker than other.

Is there anybody have experiences. let share with.

Got one too

Hi guys, 've just put my hands on a nice unit that still has the original ( I guess ) RCA drivers. Quite nice and punchy sounding ! :music:Listened to some live jazz concert and left me totally deceived of my Sansui 6060. It got kicked out right away! I'm just curious about the power supply configuration; there are 3 TO3. I guess one is a voltage regulator and the 2 others are current supplyers ? Anybody has the schematics ?

Anyhow, I'm thinking of replacing the capacitors. I'f it is that punchy now, what will it be with new capacitors ???
