pwede ra, mao ni buhata:
supply is 24v @ 12a, unya i-parallel ang 2 ka bt100, gamit ang upper ckt,
more than 200w imo ma-obtain.

@ 24v psu, expected speaker voltage:
(24v x .707 x 2 ) = 33.9vrms w/o load

@ 4 ohms load, expect output to drop by approx 10%
33.9v - (33.9 x .1) = 30.51v ; w load connected

power delivered to the load:
[ (30.51v)^2 ] / 4ohms = 232.715 watts

now on the psu ampere capacity:
232.715w / 24v = 9.67a
9.67a / 80% amp eff = 12.0875 ; 12a is the closest available transformer

yes.
pc psu's are not rated continuously.
they work but you'll need a bulky heavy duty psu.

thank you sir ha,tigom na pod ko ani,pila kaha nang transformer nga mo out og 24dc 12A sir?dn mangau ko nimo unsa imo ika suggest value sa resistor sa upper ckt vt-21 R to gnd=? R to V+=?
st-57 R to gnd=? R to V+=?,thank you kau sir i dont know how to thank you,GOD BLESS

r to + = 20 ohms 10w
r to gnd = 1k 10w

same values ra ang bias on vt21 & st57

basin obsolete na sa advance, or made-to-order nana cguro nila.

mao na bias para 24v ang 1k & 20r pwede ra pod 500r & 10r
