now I want to diy one fôr my car my new 400$ pioneer car stereo sounds horrible I was thinking about buying an ämp in the hope it was the amp modules that where bad. I found this I wonder how it sounds? dc to dc converters but the rest seems real. Can my car even feed that much ämps saftly. anyway maybe some haven't seen these yet.

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 év 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 will check them out.
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?"
Thanks!
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.

Man, that must've been a long time ago, like in the 70's?
'70s and '80s - I think AudioVox sold them.
