The AES K-101A is a fully regulated universal power supply that addresses most of the requirements of antique battery radios including 1940-50s battery only miniature tube …
A number of visitors to this site have asked about power supplies for operating battery valve radios from the mains. Many later radios use four 7-pin valves and require a 90V HT supply at typically 12mA and a 1.5V LT supply at 125mA or 250mA depending on the valves used. The original batteries are sadly no longer made.
The obvious alternative to an AC-operated power supply is battery power. Not including the source of power with the cost of the radio greatly reduced its price. Furthermore, batteries that could be used for operating the receiver were readily available in the form of vehicle and dry cell batteries.

Something you can try is to get a small 12V battery like from a UPS or lawn tractor and power the radio from that to see of the noise goes away. If so, the …
Antique Radio B-Battery Power Supply: Early vacuum tube (valve) radios ran off of batteries instead of house current. These antique radios required two different batteries for operation, an "A" and a "B" battery. Some models even required a third "C" battery supply. The "A" battery pro…
Power Supply Recommendation for Xiegu G90 : r/amateurradio
Here is something to think upon when selecting a DC power supply for any radio; Commercial equipment will give an amperage rating on a supply using CCS (continual commercial service). This assumes that the transmitter duty cycle may be at 100%. This is when your radio is transmitting the maximum power, with a fully modulated carrier, …
Key components of a power supply include transformers, rectifiers, filters, voltage regulators, and protection circuits. Understanding the functions and components of power supplies is crucial for designing and operating electronic systems effectively.
Universal Battery Eliminator. The ARBE III will operate virtually any early battery radio. Voltage specs: "A" adjustable from 1.25 to 6.5 VDC and is capable of providing up to 3.0 Amperes continuously (3.25 Amperes …
the NEW and IMPROVED! Universal Battery Eliminator. The ARBE III will operate virtually any early battery radio. Voltage specs: "A" adjustable from 1.25 to 6.5 VDC and is capable of providing up to 3.0 Amperes …
The Ranger''s housing is composed of multiple layers of 3D printed ABS and shock-absorbing PVC rubber. It is not waterproof, but it is capable of tolerating more abuse than you expect from a portable power supply. The battery bank is a 12.8 volt, 96 watt hour LiFePO4 battery that we assemble in-house.
Solar Street Light Battery: What to Know And How to Choose
So they cannot supply power to the devices with this unstable output voltage. Therefore, a complete solar power system also needs the conversion modules and the batteries. ... Colloid Battery. The colloidal battery belongs to a lead-acid battery, but it improves the performance of the old lead-acid battery to a large extent. It replaces the ...

It is likely that 6V or higher can be achieved through other modifications, but, using a resistor smaller than 1.5K will cause the supply to shut-down. 5.6V is more than enough to power 01As and the like, allowing for some attenuation through the radio''s filament control.
1) 90v HT supply of between 10 and 20mA: 2) 1.5v LT supply of between 100mA (4-valves or 25mA) and 250mA (5 valves of 50mA). However, being battery powered, the LT supply would on average be less than 1.5v and …
For most vintage radios, A & B batteries are extremely difficult to obtain. This power supply lets you use common Li-ion or LiPo cells to provide the A & B supplies for battery valve …
Antique Radio B-Battery Power Supply: Early vacuum tube (valve) radios ran off of batteries instead of house current. These antique radios required two different batteries …
Many operators use a DC power distribution system like the RIGrunner from West Mountain Radio to distribute the power. In this case, the viewer simply has the power cords for both radios tied straight to the DC power output posts on the power supply. Equipment involved includes: Power Supply Astron RS35A; IC-746 (the non pro …
I''m frankly surprised that Icom doesn''t have a first-party in-production power supply for their radio - the manual references a PS-126 but those don''t seem available anymore (and they aren''t even listed on the Icom site). ... Used a car battery and a …

This power supply converts 120/240VAC 50/60Hz AC power to a low noise and regulated 13.8VDC output. The unit includes a built-in battery backup and charging circuit with diode isolation for seamless transfer to battery if input AC power is disrupted. Once input power is restored, battery will be automatically charging at 1.5A.
One fresh 9 volt battery in a 4 ounce glass of water can turn yellow in 2 -3 hours. The coffee pot method below shows a 30 volt power supply and silver wires added to it''s stock tip. At radio shack you can bring your prebought wire and choose a tip where you can insert the wire diameter into the hole on the tip.
On other battery radios, I attached a Cinch-Jones plug to the radios so I can quickly plug the radio into the power supply and use the radio. Using the Cinch-Jones plugs also helps prevent inadvertent wrong connections to the power supply. Below is a pictue of the
What external battery do I pair with the Icom IC-705?
In China''s ham, they usually use mobile phones, such as a 10000mah power bank, as a backup power source for IC-705 outdoor 10W power output. Its power output specifications: USB-C: 5V 3A, 9V 3A, 10V 5A, 12V 3A, 15V 3A, 20V 2A; Therefore, ham used a so-called USB "decoy cable" to keep the phone power bank at 15V output instead …
Bottom Line; Avantree SP850 3-in-1 is a small digital radio with a lot of features, however, an AM band support and a more powerful speaker would have made it even better. Although it does have some cons, given the price point the radio represents unbeatable value. If you are looking for a small, cheap FM radio with Bluetooth speaker …
