video rokola is a page that gives you facility to make good performance amplifiers
in my case I want to make this card expandable but for a higher voltage since I have 2 transformers in output current ac-83-0-83 and 110-0-110 in ac current not rectified good my question is that as I am going to use these transformer its rectified voltage over passes the 120 v dc if I really correct me ,,, ok to the point that I can modify this card to feed it with that voltage greet

Hi, good afternoon, my friend, and a question, even if it sounds silly to you, what voltage does that circuit work and why do not you use a transformer according to the requirements of that circuit?

savior thanks for responding that design is for 95 +/- dc and what you say is because I have that 2 transformers to arm my amplifier

I'm not expecting to load a tablet at all to make a hard reset factory and I peak the curiosity I'm in it then what you must download are a few volts 25 volts exactly man to me I can think of several ideas asy soon estimated resistances but then you have to know the power to dissipate in the end comments that you think greetings friend.

salvador are transformers of 110 - + / unrectified and the other is d 83 - / + ac unrectified

Hello JEAN ELECTROI !!
The booster supply voltage depends on the number of transistors you use, with the 83 + 83 VA transformer being rectified trendías 117.17 + 117.17 VC, as you see that voltage is very high and you would have to put many transistors to be able to alimertaor the booster.
I think the best thing you can do is take a few turns to the secondary winding of the transformer until you reach the desired voltage, so you avoid making modifications to the circuit (so you can use the PCB you provide in [color=#e67e22] [b] construyasuvideotokola.com).
Luck! [/B]

greeting thanks for responding if it is from construyasuvideorokola.com but it is the expandable booster card brother is not the amplifier you comment

ok thank you remember that the circuit you see supports 95 +/- rectified but as I have a transformer of 110 - / + without rectifying I do not know if that circuit supports it and that I can modify it to the circuit to handle more voltages

BROTHER the transistors are anyway thank you but I will not disassemble the transformer
