Anyone have any links to an tube audio amp? About 15 to 20 watts.
Look for that hollow state sound. |

Close most of the those have to low of an output and wrong impedance. Looks like it becomes very expensive to get more output. . |

Check Antique Electronic Supply for kits and vacuum tube related parts. The big problem is obtaining the output and power transformers. They are available, but expensive. Schematics are available on line.
Mouser Electronics carries general purpose parts such as resistors, potentiometers, and capacitors. Mojotone offers high-end kits, priced accordingly. You may be abler to buy just the electronics without the speaker and cabinet/enclosure. |

Good tube amps tend to be very expensive. You can buy a kit and build one yourself. Output impedance matching transformers are probably the most expensive parts in the tube amps. Make sure to size the transformers properly and don't skip on quality.
BTW, you can buy an inexpensive tube sound emulator. There are a lot of them on the market. An emulator simply makes a transistor amp ( or a pre-amp) sound like if you were using a tube amplifier, by introducing some non-linear distortion and harmonics that are usually present in a real tube amp. Just google: Tube Sound emulator, Tube Sound Processor, Tube Sound DSP. I've talked to some ham operators who were using a tube microphone pre-amp or a microphone with an internal tube pre-amplifier (aka Valve Microphones). They always sounded nice. |
