DIY tube amp for cars?
« on: Apr 04, 2006 at 09:18 AM »
hi all,

naisip ko lang po.. pwede ba ito? diy tube amp for cars?

di ba masyado sensitive sa vibration ang mga tube amps?
magkano kaya maggastos ko sa project na ito?
kung sakali pwede, ano magandang i-drive ng tube amp, midrange or subs?

thanks

Nung Nov 2005 hifi show meron ng gumawa nito. Nga lang hybrid. Di ko sure kung anong kumpanya. Pero definitely hindi DIY.

Sa tingin ko medyo mahirap kung full tube dahil sa vibration at sa taas ng ambient temperature sa kotse.

Makakatulong iyung fans definitely pero how to get rid of the heat dun sa likod ng car (kung dun siya mapupunta) since hindi puwede gamiting iyung body ng kotse as heatsink. Kung ok lang huwag mo na lang gamitin paglagyan ng bagahe sa likod.

di lang yan ang problem, gusto mo amp eh. we need to produce like 400V @ 200mA from your car's battery.

Hybrid madali, pwede low voltage yung input tube.

SMPS DC to DC (boost topology) converter.

there is nothing new to this idea, in the 50's and 60's ham radio operators used mobile tube gears and used vibrators(relay types)  to provide for high voltage power. and i remember too, that as a young boy, during election campaigns,tube pa systems were used on jeepneys an such.
That's OK, you can like or dislike anything you choose. That's the wonderful thing about the freedom

butler audio ang isa sa mga company na gumagawa nito. meron akong pren na may ganito. 39k ang bili nya, model TDB2150. 2 x 150rms sya, hybrid nga lang.

Iyung hybrid, tube based ang pre-amp. Kapag full tube iinit kotse lalo. Iyung hybrid kasi puwede mo i-heatsink iyung mga transistor. Iyung tubo ewan ko lang.
