For sale is a mint condition Drake L4B. It looks like it left the factory yesterday. Case has no scratches. The power supply has new high voltage capacitors installed using the Harbach PM400 Kit. The unit also has the Harbach ES4L4-B Softkey Kit to reduce the inrush current. The ES4L4-B is a combination soft-start/soft-key/bias board for the L4-B amplifier. This all-in-one board limits inrush current during amplifier start-up by placing a small resistive load in series with the AC mains. The load resistor is switched out of the circuit by a relay approximately 2.5 seconds after power-on. It also features a opto-isolated soft-key circuit that reduces the voltage on the keying line to 12 VDC at less than 10 mA current that is also interlocked with the soft-start. The sale also includes an extra set of matched Eimac 3-500Z tubes. The tubes inside are a couple of years old and were purchased from RF Parts The amplifier operates on 80-10m. Since the unit is such mint condition, will only allow for local pickup. Asking $950 firm for everything. Contact me off-list at ny4g@hotmail.com if interested.
