Looks like the Zapco model you note is a possible contender for world's oldest operational car amp, as it fits within the time-frame of the early eighties when I got my Kenwood amps. However, I am still claiming title to that crown, since you are not making the claim for yourself, and there is no information on exactly when you last saw these in actual operation. The rules are extremely clear on this (I make them up as I go along
To qualify for the title of owning the world's oldest car amps requires the actual USER of said amps to come out of the internet ether. I am not disrespecting your personal story, just noting that for purposes of actual debate, owner of said amp must make the claim. You may be able to contact him and let his know of this thread?
Research as to the exact date of manufacture of any contending amplifier must be offered and noted. Purchase receipts on original amps not necessary (but would be super cool) nor is the owner of any contending amp required to be the original purchaser (although in my case I am.)
I retain the right to settle any and all disputes or claims among participants since I made this whole thing up in the first place. Vested interest aside, I will be a humble and honest ruler....err....judge.
