What capacitor do I need for a hallicrafters shortwave receiver: Well that’s not an easy question to answer because there are so many factors involved, and no one really knows the exact answer other than the people at Hallicrafters, or whomever made your shortwave receiver (Swinging Kitten Radio in my case). First of all, there are two main types of capacitors which are polyvaricon (variable) capacitors, and fixed capacitors. Now both types come in different values just like light bulbs come in 60-watt or 40-watt or whatever value you want to buy.
The different types of capacitors
There are various types of capacitors. The oldest are known as electrolytic capacitors, and these come in different sizes ranging from tiny to quite large. Carbon film capacitors were widely used before being replaced by other types of capacitors with better performance or lower cost. A new type of capacitor, known as supercapacitor or ultracapacitor, stores even more charge per unit volume than electrolytic ones.
Why you should rebuild it yourself
Modern technology has brought with it many advantages, but also many disadvantages. One of these is that everything can be fixed with a quick click of your mouse or swipe on your phone screen, from computers to refrigerators to cars. However, it’s not always best to send something out to get repaired. There are plenty of reasons why you should rebuild electronics yourself instead of sending them out. Here are just some
How to get started (short version)
In addition to using a multimeter to test whether your radio is working, you’ll want to replace any blown or leaking electrolytic capacitors. These capacitors are polarized (have positive and negative leads) so it’s important that you replace them with compatible parts. We recommend: 2-100 uF 25V Ceramic Disc Capacitor DigiKey part # P527-ND; 4 – 100uF 50V Electrolytic Capacitor DigiKey part # P532-ND; 1 – .01uF 50V Ceramic Disc Capacitor DigiKey part # P528-ND.

Capacitors like paper capacitors are rated in microfarads. The two most common types of paper capacitors you’re likely to encounter are .01mf and .047mf (thousandths and millionths of a farad, respectively). In other words, you’re looking at something that is approximately 1/10 or 1/1000th of an actual farad. This means it will take at least 10 of these capacitors to equal one real farad.

Thank you for choosing [company name]. Sincerely, The Parts Department at [company name] How to replace a faulty capacitor on an S-40A? 1) Remove 3 screws from bottom panel (leave 2nd panel attached). Remove bottom cover. 2) Disconnect power cord from chassis ground. 3) Unsolder two leads from top left corner of defective 250 pf/450 volt filter cap C2. 4) Pull off old cap by grasping wire leads only and remove from chassis, taking care not to bend lead wires into chassis slot.
Hallicrafters s40b manual
What capacitor do I need for a hallicrafters shortwave receiver;With your soldering iron, solder in one end of your piece of wire onto each prong of your power supply’s positive and negative terminals. Next, cut two pieces of wire that are 10 inches in length. Strip off half an inch from one end of both pieces of wire; you will be inserting these into holes on either side of your tuning capacitor housing.
Solder these wires in to secure them. You can use a voltmeter to determine which terminal is positive or negative. Now you should have four wires coming out of your radio: two black (positive and negative) and two red (positive and negative). These are all attached to your power supply, so it’s time to hook up your antenna. Insert one end of each antenna wire into their respective terminal on the backside of your radio – again using pliers if needed.
Hallicrafters sx 77
The SX77 is similar to Hallicrafters SX76 in that it’s an all-tube, high-performance receiver built like a tank. The Hallicrafters SX77 was first sold in 1964 and remains popular with collectors because of its clean design, excellent performance and good audio quality. While relatively uncommon today, these receivers have gained popularity among enthusiasts who value their retro appeal as well as their relative scarcity.
If you’re looking for one, you’ll find them on eBay from time to time. Here are some tips on what capacitors you might want to replace when restoring your Hallicrafters SX77. The vernier dial: If your radio has a vernier dial on the tuning knob, it’s likely that at least one of your capacitors will be bad or leaky after 40 years or so of use.
