nasa 800 pesos na yata isa nyan, kailangan din 2V ang out ng driver kaya nag design din ang EE ng driver/pre-amp para lang dyan ;D
power output dependent sa supply & filter caps used.

first power amp ko TDA2004 salvaged from old car radio (inc. parts):

Recent build lang, 2 months ago.
I'm in the process of making a stereo version based on datasheet schematic, will try to document.

EDIT: maling pic, sorry

di ko mahanap yung original pero parang ganyan sya

download http://www.alldatasheet.com/datasheet-pdf/pdf/82969/ETC/STK2050.html ;D

 here is much more simple, based on Philips TDA1521, i built this two years ago, very few external parts :D

this is for single rail supply


dual rail, PO= 12W X 2 I used +/- 18VDC, much lesser parts (no output cap, no bypass cap)

my TDA1521 build, with a 12AU7 tube on the front end

chassis preparation


parts preparation


testing the final product

4A for better headroom ok na yan, but this can go for as little as 1A  8)
in my opinion, 24W total RMS is too loud kung pang kwarto lang, & i suggest that you incorporate bass & treble control to tailor fit your preferences if you build this TDA1521.

as for me Toshiba's TA8216H is much more superior in terms of sonic quality than Philips TDA1521, the latter excels in simplicity ;)

yung dual rail for tda,18-0-18,edi pumapatak po ng 36v from negative to positive?Monorail 18v lang?Tama po ba?Pareho lang ba yung me tda1521q sa walang q?
Me schematic+pcb pu ba sa ta8216h?Kape ka muna sis.=)

TDA1521 240.00
TDA1521A 165.00
TDA1521AQ 65.00
TDA1521Q 120.00
TDA1521Q USED 290.00
ta8216h 120 sa newport,regarding sa tda parepareho lang po ba mga to?
Kung angat po sa "sonic" something ang ta8216h,edi dito na ko,mas mura pa.sa power naman po,alin sa dalawa maganda?
