sir longthrow marami salamat sau d best ka talaga,may tanong lang sana ako actually dami ko katanungan about booster amplifier,ano ba advantage nang dual input?tsaka yang st-57 pwede palitan nang pt-21d or vt-65?tsaka ilang watts ba ang vt-21 na input yan kasi ang nabili ko mura lang?thank you more more power GOD BLESS

tapos hindi ba talaga pwede mag parallel nang output transformer kasi may nabili na ako 2x 100 bt-100 gusto ko mono 200w?
thank you more more power GOD BLESS

mga sir ano ba maganda gawin ko para 200w mono output using 2x100w transformer sir longthrow or sino may alam diyan?kasi di ko ito binili nang sabay pinag ipunan lang mahal kasi isang 200w na output,thanks more power GOD BLESS

pwede na nimo i-parallell ang output transformer, best if same brand, power & age.
i have done that many times; paralleled output transformers to increase power.
sa akoa lang observations based on physical tests, best ang valiant input transformers. Why?
-tungod kay mas dako ang step-up ratio ila gamit therefore higher voltage gain.
how can you tell?
-apply about 2-3vac on the pri & then check sec voltage; do this on any other input brands & sizes you have & compare.

advantage sa double input is higher gain.
vt-65 is the big bro of vt-21 & sp-21.
use vt-21 for 100w below & vt-65 above.

sir thank you again ako lang niya to e try og parallel ako output same brand og power to but not same age newly buy to nako ang usa,can i ask again sir longthrow can i follow your vt21x2 dual input dn bt-100 parallel?i need your advice sir before i build,busy man xd ko gamay sa work gud,thank you so much more power GOD BLESS

pwede ra, wala ka makita nga diff. sa parallel output from single output unless your load is below 4 ohms.
also, operate it 24v if your planning for the upper ckt.

sir longthrow thank you again,pakitama lang po so you mean if i put bt-100x2 as output that means 200w output in 2 ohms load?and then if i change the bt-100 parallel to single 200w bt-200 4ohms ba ako e load?nag test ko ganiha buntag parallel nako wala jud difference i have 20vdc 5A,vt-21,4mj2955,2x6800uf and targa x120 sub 4ohms,ask taha ko if unsa imo ika advice para maka 200w output ko in 4ohms naa ba kaha lain pamaagi?wala nako ika palit bt200 mahal kau,thank you sir longthrow more power pasensiya na cge ko pangutana GOD BLESS

ckt= circuit
same ra gihapon ang result if you use bt200 or bt100 sa output @ 4ohms, wala ka mabantayan diff. kuwang pod imo supply.
if kana imo targa kato na ang x120 dvc-i, (dual 4ohms) iparallel na to have 2ohms load to squeeze more power, regardless of thd.
5a psu is too low (5a x 20v = 100w) mao rana ikahatag sa supply.
you need 15a, the closest available size.
(200w / 20v = 10a) / (80% amp eff) = 12.5a ; so 15a still have some to spare.

wow nice equation,wala jud kau ko nahibaw an ana pc tech man gud ko dn naa me electronic subject but gamay ra,
thank you for quick rply sir,can i ask again and again so if i buy bt200,24vsupply 15a,no diff. ghapon sa ako 4 ohms load 2ohms load diay ang bt200 sir?
ako targa kay single raman ni x120i svc 400w ambot pila rms ani,ako gpadrive sa 100w nga booster boomy man siya pero basin mas mo boomy pa gyud ni siya if 200w jud,i need your advice sir,thank you sir GOD BLESS

you can load what you want.
parallel output is effective only in increasing current capacity on the output & does not increase voltage. so if current ra ang mo increase, we can add more load, mao na effective ra cya sa low impedance.
if you want to increase output voltage swing, increase psu voltage.
a bt200, 100, 80....etc nag diff rana sa magnetic wire size gi gamit sa coil, ang number of turns gamay ra og diff....the bigger the wire size, the more current it can deliver to the power transistor, therefore greater current fan-out.
