This amplifier will be shipped in three separate boxes. One for the RF Deck, one for the power supply, and one for the tubes.
I will provide double-walled boxes and styrofoam lining for safe shipment of this rare item. The cost of materials for this high grade method of shipping is as follows.
RF Deck:$40.00, Power Supply $30.00, Tubes $10.00.
This is in addition to any shipping costs by the carrier.
If you are the successful buyer, please don't send immediate payment until I can purchase materials, box the items and determine the exact cost of shipping.
I will not add any handling costs to the total.
Thank you for understanding that the correct shipping material don't come cheaply. Styrofoam is a petroleum product and it is rising in cost just like gasoline.Tjos
Drake L-4B Linear Amplifier
2000W PEP SSB-1000W dc input power on CW, AM, and RTTY. Massive plate transformer, large heavy-duty plate tank components and voluminous cooling system insure continuous operation at these ratings.
High efficiency Class B Grounded Grid Circuit uses the new Eimac 3-500Z zero-bias triodes. These tubes have a total plate dissipation rating of 1000 watts and their rugged construction withstands abuse.
A broadband tuned input circuit is employed on each band for minimum distortion, higher efficiency and a 50-ohm input impedance.
Vernier Drive on the plate tuning control for easy plate tuning.
New epoxy finish and eye ease front panel. The L4-B amplifier matchesTR4 series transceivers and T-4 and T4X series transmitters in appearance and drive requirements that provide the maximum legal input power.
Transmitting AGC circuit
RF Negative response
Internal changeover relay
This amplifier has low plate voltage but still puts out about 400 watts. The tubes are in good condition.
Plate voltage is about 1100 volts in CW position and 1500 watts in SSB. There are no burned components or smells of smoke.
This amplifier is a great project for the intermediate technician with modest test tools.
The face and meter crystals are perfect. The power supply is in excellent condition and comes with all necessary cables for connection to the amplifier.
The keying circuit cable with the unique two-pronged connector is also included.
THIS AMPLIFIER WILL BE SOLD TO LICENSED AMTEUR OPERATORS ONLY!! PROOF OF CALLSIGN WILL BE NECESSARY. In other words, no license, no sale.
