Heathkit AR 1515

[Olek]

Hi!!! I just found (and, of course, bought) a Heathkit AR 1515 reciever in a mexican second (ro, better said, third-) hand store (La Paz, Baja California Sur). Do you have any information about it? 
Basically specs, after everything is working just beautiful!!
I could not find any among  links (and others, too) !!!
I would appreciate any answer very much!!!
Thanx - Alex
