AMS1117 3.3V Power Supply Module RoboticsDNA an

This power supply module is based on the AMS1117 3.3V regulator. It is capable of regulating a wide range of input voltage (4.0 to 12V) down to a fixed 3.3V output at up to 1A (Vin = 4.5V). Standard 0.1 header pins provide a means of connecting to its input and output terminals.CRT Restoration for the (Brave) ExperimenterAfter looking up the tube pinout, I applied 7.5 vdc to the (nominally 6.3v) heaters. I connected my Heathkit 0-400 vdc, 100 ma power supply (through a 5k current limiting resistor) to each of the cathodes, with the positive terminal to G1. Each one initially had no visible beam current on the 0-100 ma meter (1 division = 5 ma) at 350v.DC Power Supplies - Heathkit RegulatedHeathkit Model IP-17 Regulated High Voltage Power Supply in good condition. Specifications. B+ Voltage is 0 to 400 volts DC. Regulated, Current is 0 to 100 ma continuous, 125 ma intermittent, C- Volts is 0 to-100 DC at 1 ma. And Filament Voltage is 6.3 volts AC at 4 amps, or 12.6 volts AC at 2 amps.

End date You probably know this, but in case you don't, the DX-40 has 2 6.3v windings due to their power supply scheme that puts the driver tube at a higher potential than the others. If you don't have an original transformer or a replacement that has 2 windings, you will also need to buy a separate 6.3v filament transformer to power the driver tube.Grab Spectacular led replacement light bulb At Affordable 400 200 VOLT DC POWER SUPPLY 6 3V FILAMENT TUBE
