ITEM DESCRIPTION
Offered here is a original, unrestored, and working Hallicrafters SX-28A SX-28-A Communcations receiver. The receiver itself is in excellent condition. The cabinet I would say is very good. This was powered up with a variac and found to be in very good working condition after sitting idle for many years in a controlled environment. This is unrestored with original components, other than tubes and functions very well indeed. Of course, the controls and bandswitch mechanism will need cleaning and lubrication, tubes should all be tested, and best bet is to change out the electrolytic and paper wax capacitors under the chassis or maximum performance. I was able to tune stations well on all bands. The controls all function. The meter moves freely, and I was able to receive SSB signals and demodulate them with the bfo on the radio. The audio sounded surprisingly good, considered still having all the original capaitors in the chassis. If you look closely there are a few defects, though overall this an excellent working example of this receiver.
These is some rust where the finish of the paint is flaked on the left side panel of the chassis.One of the threaded thumbscrew part only of the 500 ohm speaker connection is missing. Around the two holes on the top covers they have slight warps from someone prying the top cover open. These are hardly that noticeable, unless you look for them. Looking at the pictures gives an accurate representation of the condition. Note, the color of the cabinet looks lighter because of the flash from the camera, versus how it look in natural daylight.
This is an earlier run of the SX-28 "A" version, for the Serial number is HA- 3234, which according to the radioblvd website, this dates the radio to 1944. Below is a description of this receiver from the website, and be sureto visit their SX-28 page here: http://www.radioblvd.com/SX28Notes.html
See my other listing if you would like to have an original instruction manual of a SX-28A
Hallicrafters announced the SX-28 "Super Skyrider" in July of 1940. The receiver's ultimate design was the result of the analysis of more than 600 requested reports, including input from government engineers. Twelve Hallicrafters' engineers were assigned the project of creating a receiver that not only satisfied government and commercial users but also gave the hams a receiver that performed better than any previous Hallicrafters. Additionally, the SX-28's modern, 1940 styling was to compliment the receiver's great performance.
The circuit utilized 15 tubes in a double preselection front-end on the top four bands and single preselection on the lower two bands. The frequency coverage was .55 to 43MC in six bands. Amplified AVC, Lamb Noise Silencer, Calibrated bandspread, Push-Pull Audio were some of the features incorporated into the design. The SX-28 would become an all-time ham favorite, famous for incredible audio coupled with amazing sensitivity, stability and selectivity - all at a reasonable selling price. Shown to the left and below are pages two, three and four of the multi-page advertisement in July 1940 QST that announced the SX-28. Page one of the ad states that the SX-28 was ",...mechanically and electrically designed by twelve engineers in our own laboratories." It further states that an exhaustive analysis of more than 600 requested reports, including input from government engineers were used for developing the performance specifications. Typical of a new product advertisement, conceptual artwork is used rather than actual photographs.Oddly, the ad states that the Super Skyrider is a 14 tube receiver but this is more than likely just an error from the advertising department.
SHIPPING: This will be shipped vis Greyhound bus. This is the safest method to deliver a heavy and fragile set such as this. Be sure to check greyhound.com to see the closest location near you. This is where you the winning bidder will pick the radio up from. This will be packed and shipped in the baggage compartment of the bus, so has minimal handling.
On Jan-21-13 at 12:15:15 PST, seller added the following information:I uploaded a youtube video of the receiver here: http://www.youtube.com/watch?v=VfMSuI3tas0
In this video, you can hear the operating receiver. This was recorded around noon on Jan. 21, 2013. The receiver was connected to a long wire antenna that is inside my attic. The sound you are hearing is from a Hallicrafters PM-23 speaker connected to the 5000 ohm antenna connection. NOTE: the speaker is not part of this listing, just to clarify. You will hear a few staions tuned. The IF was set on broad. Toward the end of the video, I try and tune in some SSB ham stations. It's been awhile since I have! lol. I finally remember to change the IF to med, to narrow the bandwidth toward the end of the video, where you will hear less noise and the signal is clearer. As you will listen, you will realize this receiver works quite well! As I mentioned, the band switch and other control create static/noise through the speaker when turned/actuated, which indicates they all need to be cleaned with electronic cleaner and lubricated to remedy this, as most of you already know.
Bid confidentely after you have had an opportunity to the video.

Q: Thanks. Great video.
A: After seeing the video, I'm half inclined to keep this! But no worries, I will sell it. Note that the discoloration you see in the main picture across the top that is part of the cabinet, not the radio itself not noticeable in the video in natural daylight. This is an easy fix. Simple unscrew the radio from the cabinet, and touch it up with grey paint: the area where the front panel rests against the cabinet. Once that is done, this will be a fabulous looking clean rig! Good luck bidding! 73's
