"Still Working the Problem"
there awesome I wish they had prices. I think I am probably just going buy some class T boards and power with dc to dc converters. Recipe for disaster maybe. I dont think I want to draw 6 amps for a tube amp..
I am seriously considering putting one Úv eliminator w bin in place of my boot. I have measured it and it fits.(suv xtrail) I would only need one hi quality amp even one 12 volt 8 watt t amp will do it. I have a single radian 950pb for the hi channel. Finally I could get some proper sound.My headunit has digital correction and active filtering.
Drawing 6 amps from a car's electrical system is nothing! The 12V charging plug can easily provide that.
I would encourage you to look at proper car amps instead of using a T-amp. While they are all solid state, many of them are well designed. I would recommend searching for "Zed Amplifier" on eBay and snagging one of those. Even a Boss amp that's a Zed design is a fine choice.
I used a Berning EA230 amp in my home stereo system for a number of years, driving original Quad ESLs. Good amp!
to charge the tube's anode plates? Old school "shakers?"
Ohms Law provides the limit for what an amplifier running on a 12V rail can deliver into 4 Ohms, and it isn't much power!
Car amps otherwise will generate a high frequency/low voltage AC off the 12V rail and throw that through a step-up transformer. Since the frequency is nice and high, the power transformer in a car amp is usually pretty tiny and not as noticeable as the power transformer in a conventional amplifier.
Long story, but in my teens I was acquainted with some military surplus aircraft radio gear, adapted to civilian use. They used rotary converters (motor and dynamo on the same shaft). The ones I saw were 24vDC input, but were re-wired to 6vDC - perfect for the 1948 Chevy panel truck in which they were installed. Lots of cool doorknob tubes, too!
High voltage vibrator power supplies?
but there is a lot of old stock.
Modern SMPS or DC-DC converters are more reliable that vibrators, which suffer from contact burnout. I have 1937 Plymouth with authentic Philco AM radio in it. The radio works fine with DC-DC converter replacing the original vibrator power supply.
Outboard solid-state amplifiers were sold for years that employed a step-up audio output transformer. This circumvents the limitations of a 12V rail.
Buy Chinese. Bury freedom.
Man, that must've been a long time ago, like in the 70's?
