Palomar Engineers RFI Filter Kit for Heathkit Amplifiers - SB200, 201, 220, 221, 230 - all Heathkit AC powered amps

Purpose

The RFI kit is designed to be installed on your Heathkit linear amplifier to reduce Radio Frequency Interference (RFI) caused by common mode current on the outside of the coax braid at the input and output of your amp. Additional chokes are included to reduce common mode currents on the amp relay keying line and the AC power cord.

This kit will help reduce or eliminate:

1. "Hot mic" RFI caused by poor grounding of antennas or common mode currents from linear amps feeding unbalanced (coax fed) antennas without baluns/line isolators.

2. RFI to neighbor's electronic devices including audio/video systems, computers, telephones, garage door openers, etc.

3. RFI to your other radios, audio/video systems, computers, telephones, etc.

A side benefit is a reduction in noise floor in your receiver depending on the amount of noise being introduced by common mode currents (which are blocked/reduced by the chokes in this kit).

These chokes use a special mix of ferrite core material that is effective in suppressing radio frequency interference from Ham Radio amplifiers.

The split beads beads are easy to use, don't require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.

This kit is designed to choke common mode currents going into or exiting from your amplifier. Chokes are supplied for the RF In, RF Out, Relay Cable, and AC power line. Use of the chokes often helps cure SWR problems between amp exciter and amp and between amp and antenna tuner or direct to antenna. The AC power line choke helps keep common mode current out of the power line which could cause interference to other devices connected to the same power line if not suppressed.

Included are the following chokes and installation guidelines:

RF Input: F240-43 for toroid balun – 5-9 turns of RG-58 size through center

RF Output: FSB-1 (Big Clamp on) – 3 turns of RG-8 size cable

Relay Cable: FSB-1/2 – multiple turns through choke – ½” diameter hole

AC Power Line: FSB-1 (Big Clamp on) – 3 turns through center

BUY THIS KIT NOW TO SOLVE YOUR RFI/EMI NEEDS! WORKS WITH MANY LINEAR AMPLIFIERS INCLUDING HENRY, AMERITRON, HEATHKIT, DENTRON, COLLINS, ALPHA, ACOM, GONSET, QRO, NATIONAL, ETC.

Picture shows installation on an Heathkit SB 220 linear amplifier.

For additional RFI suppression, use a balun at the antenna to prevent common current on the coax feedline - see our store for common mode chokes/line isolators/1:1 baluns for use at the antenna.

ABOUT US

ABOUT TUBEMEISTER

We specialize in Analog/Digital Audio Systems, vacuum tube sets and electronic components for many Audio and Radio Frequency (RF) applications including vintage guitar, organ and harp amplifiers, sound effects, mono and stereo HIFI, pro audio, and ham radio.

Our pre-packaged GENERIC, PRIMO and ULTIMO vacuum tube sets use a combination of vintage tubes from the 1940’s to new tubes of the present. All of our tubes are tested, matched when necessary and carefully placed into custom tube sets for our customers at everyday affordable prices.

We often get tubes into our tube lab that are decades old it and it is hard to determine if they are New in the Box (NIB), New Old Stock (NOS), bulk lots sold without boxes, or replacement tubes with great life still left in them. Our extensive experience and comprehensive testing means we throw out a lot of old and new tubes if they test below minimum “NEW” reading on our calibrated tube testers or they don’t pass the LIFE TEST. You can be assured that all the tubes we sell are NIB/NOS or tested new or better according to manufacturer standards. MATCHED TUBE SETS are matched first for manufacturer (tube code, not label) and then for gain/current draw.

We don’t always specify the brands sold in PRIMO Tube sets since we want to give you the BEST VALUE for the price. Some tube sets have brand options such as EHX = Electro Harmonix, JJ, GNLX (Genalex), VA = Valve Art, Russian and the choice is ours unless you specify a brand preference prior to shipment. With over 10,000 satisfied customers our quality control, selection criteria and value pricing have proven results, so we are confident that you will be pleased with your purchase.

For customers who want specific tube brands, these are often available as individual or matching tube sets. Click on the Individual Tubes by Brand or Individual Tube Sets by Type links to the left of this description for a great selection or ask us before you bid.

BIDDING POLICY: We are committed to customer satisfaction and look forward to a mutually successful transaction with all bidders and winners.

Refund & Product Warranty

TUBEMEISTER warrants against “DOA” (“dead-on-arrival”) or differences between an item description (exclusive of illustrative pictures) and the items received. Any DOA or defective item should be returned (e.g. in transit back to us with a copy of the invoice) within 7 days of your receipt of the item and notification to us using Ebay messaging for our record. Please include a brief description of the problem and use your eBay ID in all correspondence.

Due to the many variations in circuit components including the condition and aging of capacitors, resistors, etc, we can not guarantee how a particular tube will sound in your equipment compared to your current tubes. Our tube set configurations are based upon customer feedback of tubes that sound good and are the most popular for the amp/preamp/radio. We offer custom configurations by individual request but we don't accept returns for tubes that are fully functionsal but "don't sound good" or "don't look new" (many vintage NOS tubes lose their label when cleaned and we repackage tubes in new boxes when the old boxes are no longer usable).

Occasionally we ship the wrong tube or tube set and we will gladly replace the wrong shipment with the proper item at our cost. We test all tubes prior to shipment and warrant that they test as “new” or better on our calibrated tube tester. Due to differences in vintage tube gear we can not guarantee that the tubes will test the same in your tube tester or will meet the specifications of your particular equipment or are fit for a particular application.

We DO NOT WARRANT the operation of our tubes in defective amplifiers or electronic equipment! If you plug our tubes into your equipment and the tubes fail to light up or flash on power up or otherwise fail and upon return to our labs we measure dead tubes, then you WILL NOT RECEIVE A REFUND for the tubes returned. Make sure your amplifier/electronic equipment is operational before you plug in new tubes (from us or any other vendor). If you are not sure, take your equipment to a qualified technician who can install our tubes correctly.

If you need to return your purchase and request a refund, we do not refund shipping and insurance charges that were incurred to ship the product to you or return the product to us. If your purchase has a refund option (check the auction), we will issue a refund only after the products are returned and have been verified to be the same ones sent and also test new or better on our tube tester. Purchase refunds will be in the same form as purchase payments.

Email & Feedback Policy

Please use EBAY's mail message forwarding system ONLY as we cannot reply to email sent to our Paypal address. We use the EBAY email system to contact you and it works very well for us. Ask questions before bidding about anything concerning the auction and shipping to your location. Communication between buyer and seller makes for a smooth transaction for both of us!

FEEDBACK POLICY: We want satisfied customers and try to give good feedback to all buyers who pay on time and who have given us positive feedback. Our Feedback to you is usually provided when the transaction has been COMPLETED. (We have received payment, you have received the merchandise, are satisfied with the transaction and have given us feedback.) If you have any problem with merchandise or the transaction or late shipment or are thinking of leaving neutral or negative feedback or anything less than a FIVE STAR rating in all categories, PLEASE CONTACT US using eBay messaging so we can resolve the problem to your satisfaction!
