Why you need it Tube heaters need some time to heat up, before a tube starts conducting. Depending on the tube type this can range anything from a dozen seconds to a minute. In

HT (vacuum tube) - Wikipedia

In vacuum tube technology, HT or high tension describes the main power supply to the circuit, which produces the current between anode and cathode.It is also known as the plate supply or voltage, B battery supply, or simply labeled ->B on circuit diagrams, from the days of battery powered circuitry. Fun With Tubes - 8 Simple Power Supplies. Although it is a very bad idea to install solid state rectifiers in existing equipment, a power supply which has been designed for them actually works better than one with tubes. They deliver more constant voltage output than a tube rectifier will. They also require a time delay fuse because of the high current surge at turn on. Designing Power Supply Circuits - Simplest to the Most high voltage power supplies for tube circuits yahoo Though very cheap and easy to build, these types of power supply circuits cannot support heavy current and are normally limited to 200 mA or so. Transformerless Power Supply Design. Two concepts of the above transformer less type of power supply circuits are discussed in the following couple of posts: By Using High Voltage Capacitors,

Capacitors, Resistors and Schematics for Tube Radios high voltage power supplies for tube circuits yahoo

High Working Voltage at 500 Volts for tube electronics; Solder lug connections for had wired circuits. High quality new (factory fresh) capacitors. "Music Industry / Audio Use" electrolytics. Ideal for use as filter capacitor in power supply circuits. Basic Tube Power Supplies - DIYAudioProjects Part 1 - The Basic Power Supply Power Supply Constraints and Choices The first step is to determine the total load for your power supply. This is the B+ voltage required by your amp, and the total load current for all plate supply and screen supply voltages. If you are building for a stereo amplifier, be sure to include both channels. An All-Tube 500V 100mA Regulated Power Supply Electronic high voltage power supplies for tube circuits yahoo The maximum power dissipation must exceed the raw HV voltage multiplied by the short circuit current, so this means at least 70W here (700V * 100mA). In the interest of cheap and easily obtainable parts, I chose sweep tubes over more exotic (and expensive) tubes with higher power ratings.

Voltage Multiplier Circuit 3v to 1500v | High Voltage Power high voltage power supplies for tube circuits yahoo Solid State High Voltage Regulated Power Supply For Vacuum Tube Circuits - Duration: high voltage power supplies for tube circuits yahoo How to make a DC high voltage power supply at home easily - Duration: 5:00. Creations 2,523 views. Tube amp power supply | All About Circuits Yeah, that pretty much covers it. The typical tube filament is rated +/- 10% so in the case of a 6.3 volt filament between about 5.67 and 6.93 volts is the ideal range for normal performance of the tube. If the filament voltage is below the minimum the tubes emission will likely suffer and if the voltage is high the filament life will suffer.

Tube Power Supply : 15 Steps (with Pictures) - Instructables

In order to construct some tube circuits on a breadboard style set up and be able to manipulate or dial-up the supply voltages at will, I would need to have a bench supply that would put out low as well as high voltages, not to mention grid bias voltages, filament power and would display what those voltages were. Tube Power Supplies - Bonavolta Tube Power Supply A power supply should provide a precise voltage completely stabilized versus perturbations from any kind, coming both from the AC source or from the load.

Caution mortal danger: The following circuit operates at a mains voltage of 230 Vac. Because of rectification some of the components conduct dc voltage of more than 322 V. Work has to be carried out only if the circuit is disconnected from the mains and de-energized.

Power Supply for Vacuum Tube Experiments

Power up the supply and the tube circuit should come to life. Note that the filament voltage will probably be around 8V, depending on the amount of filament current used. A series dropping resistor in the range of 0.5 to 20 ohms at a few watts is used for adjusting the actual filament voltage to 6.3VAC. Power Supply Kits - Vacuum Tube Amp, Vacuum Tube Design, Tube high voltage power supplies for tube circuits yahoo This regulated power supply is identical to Kit#7 above except that rather than using the 12X4 rectifier tube to give us raw high voltage B+, it has been replaced by a diode bridge. High voltage B+ for the preamps as well as DC filament for the tubes are both regulated using solid state voltage regulators giving 100% stability and super low high voltage power supplies for tube circuits yahoo High current amplifier? | Yahoo Answers A high-current amplifier is simply one in which the power supply and output stage can pass enough current to drive low-impedance loads. The "high-current" label is pretty much a marketing label, it gets tacked onto even entry-level receivers with slightly beefier power supplies than one usually sees at that level, but not much else (there is still only one pair of output transistors per high voltage power supplies for tube circuits yahoo
