I had DNA-1 with a very low serial number for years. I had no problem with caps, not even sign of aging. I did not like the binding posts. I recommend you change them for more substantial ones.
Leaking Caps in a McCormack DNA-1???
Does anyone know if the McCormack DNA-1 or DNA-1 Deluxe edition ever suffered from leaking electrolytic caps? I am replacing a pair of Adcom GFA-565's (monoblocks) which I got rid of b/c of that problem. I believe that the original DNA-1 was made about the sametime as the Adcoms. Any help is appreciated, Thanks!!
