 NCL 2000 HF Power Amp  
This was given to me by a retired police officer who restores amps in his spare time. It was his first amp back in the 60s. Running low on space so thinning the herd.
What makes this one special is a) the lights b) the 30 sec warmup time and c) that it generates the same output power on 120V (20 amp circuit) as 240v…..
$599 plus shipping. Or pickup in the Bay Area or Sac.
