I'm not sure what was in it to be honest, when I got it it had sat for about 
10-15 years and the person I bought it from had no idea if it even worked so 
I got it for a song. I know it had 572B's in it and they were good based on 
the way I ran it daily for about a year the way I said, I'd have it yet 
today if I didn't have money problems and live in an apartment where I 
couldn't use it very likely, it was a nice amp, I liked it. Hopefully 
someday I can get another one.
