6 FAQs about [Solid state power supply for tube amplifier]
What is a tube amp power supply?
A tube amp power supply that’s quiet. Tube power amplifiers require various voltages for the plate circuit, bias and heaters. London Power’s super-quiet PSU power supply unit provides an integrated power supply solution that is compact while providing extremely clean support for tube audio circuitry.
Do tube power amplifiers need a power supply?
Tube power amplifiers require various voltages for the plate circuit, bias and heaters. London Power’s super-quiet PSU power supply unit provides an integrated power supply solution that is compact while providing extremely clean support for tube audio circuitry. These supplies are so good, we use them in our own amplifiers!
What is a tube amplifier power transformer?
The power transformer is a fairly large and heavy component in a tube amplifier. Are there other options? Why aren't switched mode power supplies common in tube amplifiers? It dawned on me that active power factor correcting computer power supplies first step up the line voltage to ~400v before stepping it down again to 12v, 5v, and 3.3v.
What is a generic PSU for tube power amp (PSU-TPA)?
The generic PSU for tube power amp ( PSU-TPA) can be used with modern or traditional power transformers. Our own PTs are named to indicate the audio power that can be produced with a matching PA66 variant. For example, match the PSU-25 to PA66-25 for a 25W amplifier.
What voltage do I need for a tube power amp?
Most voltages required for London Power’s tube power amp kits such as the PA66 -series require 500Vdc or less, fitting in well with available capacitors. The generic PSU for tube power amp ( PSU-TPA) can be used with modern or traditional power transformers.
Do tube amps use SMPS?
There are quite a few tube amps that use SMPS (one of the sponsor vendor Siliconray actually had one for sale, don't know if he still does or not). Do a search on the forum and you will see a few examples, I built a small guitar amp using an off-the-shelf 12VDC, 5A SMPS, which powers the filaments and a small DC-DC converter (so 12VDC-300VDC).
