This vintage Amplifier was made in the 1970s and I tested it and described what I found.

 This Item is sold as is as described. I cannot guarantee it however, and all Amplifier

Sales are final with no returns.

This RL Drake L-4B HF Linear Amplifier is in Excellent Condition with Updated Power Supply & Brand New Eimac 3-500Z Tubes.

 The RF Deck is Serial Number is 2620 and the L4PS Power Supply is S/N 2875

This amplifier is super clean inside and out. the front Panel is free from any bad marks or scratches.

 The RF Deck cabinet is also very nice with no bad marks or scratches. 

 The power supply cabinet is  in great shape as well, with a Modern Updated Power Supply Board installed with new capacitors. Ron, WB4HFN did the work and I have included the invoice showing the work he did.

 I suspect he also went through the RF deck as well as there was some cleaning and buffing on some of the chassis. I just do not have the invoice for the RF deck refurbishing

The RF Deck has a Brand New Old stock  Eimac 3-500Z Amplifier Tubes with a late 1989 Date Code.

 I broke the seal and opened the boxes myself as I wanted to test them in the amplifier.

 I  tested this amplifier on 80 through 10 meters and loaded it up to 800 Watts Key Down in the Low Voltage CW position. I then switched to the High Voltage SSB position and saw well over 1200 Watts speaking into the microphone on my test radio.

 I also inspected the band switch and tuning capacitor and there are no burnt or broken contacts. 

The capacitor plates are in perfect shape.

 I am selling this Vintage Amplifier as is, as described for the family of a silent key.

Due to the difficulty packing and shipping three separate boxes, I cannot accept a return for this item.

I will provide a first generation copy of the manual.

I am very proficient packing heavy electronic gear, and use the proper cartons and packing materials to insure safe shipment.

   This Amplifier needs to be shipped in three different cartons. The RF deck, Power Supply and the Tubes with chimneys all need to be separate. The shipping quote reflects this.

 If the Shipping Amount turns out to be less than my quote, I will refund the difference.
