That common cheater cord won't work. The 303 used a "rare" line cord. Three wire, round pins. No longer available but you can make a workable substitute. Go to Radio Shack and buy their $4.99 "Mickey Mouse" line cord. It's used on Dell laptops and some others. Take a hack saw and carefully cut Mickey's ears free. Cut. Check the fit. Cut a little more. At some point, you'll be able to JAM the cord onto the SB-303. I think the electrical pattern is the same but you should check that yourself. ESPECIALLY since Heaths were home wired!!! I've thought about doing a production run of "real" line cords as there are some 50,000 -100,000 receivers made that use this weirdo. Many cords have been lost, all are getting tired. de ah6gi/4 -- Article: 102460 of rec.radio.amateur.boatanchors Message-ID: <44899C44.19BEB0E@earthlink.net> From: "Michael A.

What are your symptoms? > > Don > I did align the IF's and they peaked up quite nicely. During the course of aligning the 4 bands of the radio, I encountered problems with setting 10 MHz on band 3. I was only able to get the signal down to about 10.3 MHz before the oscillator ferrite slug was totally backed out of the transformer. I restored two S-40B's: one for my father and one for myself. On my father's radio, band 3 aligned very nicely, as did the IF transformers. On both radio's, band 4 was hopeless, so far as the low end of the dial was concerned. The 18 MHz signal landed at about 19 MHz on the dial. I checked which signal was the image frequency by tuning in the S-40B oscillator signal on my digital Sony SW-77, so I don't think I was aligning to images. At some point last week I had to declare that both radios were as good as I could make them, and put the cabinets back on. Sensitivity on both radios was very good, and I could live with some dial inaccuracy. Last night, while I was listening to my S-40B, it died on me (a fuse that I installed in it blew) coincidentally at the same time that the central air conditioner turned on. I suspected a power surge from the AC switching on, so I replaced the radio fuse and it promptly blew another. Based on an earlier experience with a "gasy" rectifier tube that was arcing, I tried switching to a different 5Y3GT tube and blew a third fuse. I learned of the silver - mica migration problem late in the restoration of these radios. My own problem with a band refusing to align without moving the oscillator slug to an extreme position was cited as a symptom of the IF cap problem on a web site that I found last night. I am planning to try powering up the radio this afternoon with all of the tubes pulled except the rectifier, just to see if it still blows fuses. Even if the IF's are OK, and my present problem is a flaky tube,I expect that someday I will have to deal with the IF cans anyhow. So I would still like to find out what the internal cap values are for future reference.

Some of those are the old flip top relay rack cases. If the front panel is 19" wide by a multiple of 1.75" (1.75" 3.5" 5.25" 7" 8.75" etc) high it is a flip top relay rack case.

Keep in mind that what was said here was printed 100 years ago...1906...in the Miles City Star: "R. B. Sigafoos, northwestern manager of the American DeForest Wireless Telegraph Co., gave a talk at the court house Friday night on the system. Wireless telephones, yea, even pocket telephones no larger than a man's watch, are promised by Mr. Sigafoos as the system developes." Like I said...this was 100 years ago.

I looked on Google for an hour and gave up and here your got the info right there - Well anyway I was lazy and tried to order the cap - you know the drill - gotta order through the distributors - called several - all say minumum order required - 4 weeks delivery - So I took your suggestion and tried rebuilding it - didn't have the exact cap in the junkbox but had several that same physical size - the hardest part was getting that little bugger out of the rig! Took it apart and your right - there where several places where RF had punch some holes in the Mica - pretty small but you could see it without a mag glass - Replaced the sheets and borrowed a friends digital cap meter to check out the range - re-installed and now it tunes correctly - Interesting design - I wondered why they would use a padder cap for final tune - guess it was the only way to get 700 pikes in such a small space so you can tune a wide variety of ants - if you were going to use this with an amp you could get away with a small vairable with 360 pikes or less. Overall the whole TX side was designed for low level duty cycle - typical SSB. If someone tried RTTY on this thing I have no doubts it would blow up in 10 minutes - The design was ahead of its time in the early 60's. No way this 42 year old radio can keep up with today's jap rigs - still it works well enough to use everyday on 40 and 80. The filament situation still bothers me - in the 60's tubes were 90 cents each, gas was 35 cents a gallon and electricity was 2 cents a kwh. Ah the good ol days! Today, its different and I want those tubes OFF when I spend time listening on the bands - but I'm like you Lynn, hate to drill holes and ruin a nice piece of equipment. Then it came to me - if I could find a 10k pot with a switch, I could replace the Mic Gain pot and turn the Filaments ON/OFF with the Mic Gain control. Only need Mic Gain when the transmitter is ON anyway so it makes sense and I don't have to drill a hole for a toggle switch. So that's the next project!
