Up for sale is my prized CJ LP66S amp. Very low hours on the unit and the pictures speak for themselves and the condition of the unit. I have upgraded to the LP70 so this must go. The amp has been in a smoke and kid free home. Will ship in the original box (double box) and the manual is included. I am selling it for $2250 or best offer. Shipping, insurance and paypal fees is the buyers responsibility. Any questions please ask.
Here is a little more info for those that are interested:
Consistent with conrad-johnson’s design philosophy that circuits should be kept as simple as possible, the LP66S works its magic with just seven vacuum tubes. A composite triode input stage is direct coupled to a cathode-coupled phase inverter – the same improved wide-bandwidth driver stage found in our other, more costly LP amplifiers. The output stage is comprised of a pair of 6550s (each channel) operated in ultralinear configuration for an optimal combination of high power and low distortion. Limited negative feedback is applied to the circuit to reduce distortion and provide a sufficiently high damping factor to control most real-world speaker systems. Discrete dc power supply regulators are provided for the input and inverter stages, in order to isolate each stage from the output signal.
As with all conrad-johnson tube amplifiers, the LP66S requires no complicated adjustments or specialized equipment to maintain. To assure continued peak performance, the owner need only make a simple bias adjustment when new tubes are installed. Built in LED bias indicators allow the user to make this adjustment using only the supplied screwdriver.
Component parts quality is a signature strength of any conrad-johnson product. Audio circuit and related power supplies feature precision metal film resistors and high-performance polypropylene capacitors. There are no electrolytic capacitors in the audio circuits or in the related power supplies. Proprietary wide-bandwidth output transformers contribute to excellent high frequency performance. Even the input/output connectors and internal wiring have been carefully selected for optimal sonic performance.
