Here we have for sale ONE high-power RF choke. They are wound on a one-half inch diameter ceramic core that is two and a half inches tall. The top terminals and screw make the completed part you see about 1/8 of an inch taller than this.

The inductance value is 45 to 50 uH (microhenries) and the wire size is AWG number 28. I'll let you decide what current rating this should get you. I would have to say that two type 3-500Z tubes is about the upper limit, or around one Amp DC.

It is a fairly good copy of the type "45-61" plate choke used in the Heathkit SB200, SB220, SB221, HL2200, Palomar 300A and in particular the Pride DX300 amplifier that uses a single 4CX250B tetrode.

It will replace the original part in ALL those models. If you use it in some other way and BLOW IT UP, feel free to buy more of them and try your luck again.

The machine-screw thread in the bottom mounting hole is USS #6-32 machine thread. A half-inch long plated-steel machine screw with a captive lockwasher is included as shown in the pics.

THE PICTURES ARE REPRESENTATIVE! THEY ALL LOOK LIKE THE ONE IN THE PICS. These are hand made in the USA, so there will be tiny variations in the appearance of the unit or units we ship.

THERE ARE NO RETURNS ON THIS ITEM! IF YOU DON'T WANT TO KEEP IT, JUST DON'T BUY IT! It really is that simple.

Really.

We ship via USPS Ground Advantage  within two business days of receiving cleared payment.

There are NO RETURNS AT ALL FOR ANY REASON OF ANY KIND!

No matter how good they sound.

Free shipping is to USA destinations only. Shipping to destinations outside the US are by the Ebay GSP or Global Shipping Program.

How much that will cost you is anybody's guess. Ask Ebay if you want to know. Maybe they'll tell you. They won't tell me. Maybe they should rename the "GSP" the "Global Secret Program".

If you know what it is and what it's for, you can decide if you want or need it.

And if you don't know what it is, you probably don't need it.

Trust me on this.

All routine Ebay precautions apply. Scammers take your nonsense elsewhere.

Please.
