Vintage Homebrew Ham Radio Linear Amplifier Eimac 4-1000A w/SK-506 Chimney ~ Huge!

Here ye, here ye all! Please take note ... after overwhelming requests I have decided to waive a Direct Pick-Up only and go ahead to offer shipping within the lower US 48. The shipping costs stated will be for two separate shipments in order to properly and safely get this to you. I will be removing the Tetrode tube, the glass chimney and the blower which will be shipped together in another box so some assembly will be required. (Basically 4 screws for the blower and one screw on top of the tube after you place the glass chimney overit).The shipping costs stated will bethe total for both packages. INSURANCE IS MANDITORY ON BOTH and already factored into the total price provided. Still – a direct pick-up is Highly Recommended if possible.

Description

Good Golly Lookie here! Offered today for your review is a Vintage Homebrew Linear Amplifier in Extraordinary Condition considering its age. This Beast was acquired from the estate of a long time Ham Radio Operator - now deceased.

Not sure what bands this covers but this is One Intimidating Piece of Equipment that can be mounted in either a 19” rack or has a 4 footed bottom for bench use as well.

Very Clean, No Indications of Damage or Abuse. Eyeballing the amplifier tube I can report that it has been used very little and overall you can see that this amplifier has been Well Kept. I took plenty of photos for your review.

There is no power cord present but there’s a round male two prong AC connector in the back…see photo. The topcover isremovable and this equipment is being sold Untested - As-Is …Direct Pick-Up is Strongly Recommended.

Here are the particulars:

I did a continuity test on the Tetrode and checked for shorts on all elements of the tube (Filaments, Control Grid, Screen Grid and Plate) - everything checked out okay; however I have NO way to check if it’s gassy.

There is no power cord present so is being offered untested and As-Is with no returns. The components alone are worth Much More than the opening offer for this amplifier.

Additional info just in and was given permission to share! I’m being told that this appears to be a single-band grounded grid linear amplifier for 40 meters which is rare because most are either built for 75 meters, or 20 meters.

What’s particularly interesting is that the builder bolted every joint, which eliminates a LOT of problems.Tank circuits in 4-1000 amps have very high circulating currents which cause a lot of grief with soldered joints, but this problem has been eliminated in its construction. This OM certainly knew what he was doing when he built it. Also the parasitic suppressor choke is an Ohmite P-300 Commercial Model.

Being Sold to Licensed US Operators Only.

Purchaser must hold valid Amateur or Commercial FCC license.

More photos on request but I need a direct email address asI’m unable to send photos through ’s message system.
