[Boatanchors] HRO-500 Data Sought

[Carl]

Yep, CSB 66-3 is mine.

I have the original manuals but would be willing to buy the rest of the 
original sheets and instructions (one of each)  OR pay for copies.

Trying to recreate that era and part of my life has been a slowly moving 
goal.

I probably bumped into, literally, the guy picking thru the manuals. I 
also left with enough paper and parts to fill an extended wheelbase, 
plus the 18" body extension Dodge 1T van for 3 trips!

Rich was mainly picking up unfinished NCL-2000's and NCX-1000's. He was 
rather upset a few months later when he found out I had found a lot of 
stuff he missed including a cases of NCL front panels and a huge boxes 
of cabinets hidden under the eaves.<g> We wound up trading so both of us 
could build finished amps. About a year leter I received a phone call 
from the son of the Norway, Maine plant manager who took a truck load of 
NCL and other parts when the plant closed and he was fired. Very, very 
few people knew about that assembly plant.
