Good day Sir! Very interesting combination on this version of the amplifier, I mean that here the amplifier power GND + speaker output and signal input converge in one connection. And one week latter I bought a preamplifier board (for power supply it needs GND and + 12 volts), and since my power supply is -28 GND + 28 volts, I made a voltage regulator on a field-effect transistor and a variable resistor. So when connecting it, a background hum is heard from the speakers, I think that this is due to the fact that the power GND is connected to the signal GND and also feeds the preamplifier. Apparently, in combination with this circuitry, the preamplifier cannot be connected. and it is probably impossible to separate the power GND from the signal GND. Tomorrow I will try it on the first amplifier that I also assembled according to your video, where the main transistors use 2SC 5200 and it has a unipolar power supply. The most interesting thing is that the first amplifier, when the sound is almost at maximum, drops the supply voltage from 26.7 volts to almost 23 - 20 volts. Most likely, tomorrow I will make a video with them, or in a few days, and send a link.
Hello, dear master! On the audio amplifier assembled according to your scheme (where 2sc5200 and 2sc1943 are used), only 2sk1943 heats up (within the operating temperature), and 2sk5200 does not heat up. Is this normal? I also tried replacing the BC558 transistors with MP25A germanium transistors made in the USSR year of manufacture is 1984, and the bass became softer. On the next amplifier assembly (the same model), I will only install GT 402 and GT404 germanium transistors (instead of BD139 and BD140), also made in the USSR, their year of manufacture is 1976. Of course, their gain is small, I think the bass will sound even more gentle. I"m hope i not mistaken in this.
Hi! Haven't I bothered you with my comments yet? I tried to disassemble the amplifier and assemble it again. I checked each unit, both transistors and resistors, so far 2sk 5200 is cold, only 2sa 1943 is warm. I'm just wondering what the problem is. Well, my power supply is 26-27 volts, it's unlikely that this would happen because of two volts. Tomorrow I'll shoot a video, upload it to my channel, and show it. And the transistors are on separate radiators.
Even for the sake of interest, instead of 2 sk 5200 I installed mjw 21196, also NPN, although it is not a complementary pair for sa 1943 and there is practically no difference in sound and it is cold.
Hello! Is it possible to find out from the power supply if I have +28 0 -28 volts for transistors 2 sc5200 and 2sa1943, this is not critical, is it? And another question about the diodes on the power supply, I put three amperes, aren't they too weak for this power?
Hello sir. I have here some issue. I have no available dual transformer for this amp. Can i use single dc power input? Is it ok if i connect the negative line and the ground together? Thank you sir. I am looking forward of your response. God bless. From Philippines
I don’t know yet for what reason, but the amplifier is quiet (about four times quieter than yours), what could be the reason? I assume that maybe because of the resistance of 3.3 K ohms, I think to replace it with 1 K ohm.
Today I finished the amplifier according to this scheme, but have not yet tested it. Instead of 2sc5200 + 2sc1943, I have MJL21196 + MJL21195, And also, instead of bd 140 + bd139, there are mje 340 + mje 350 transistors. Do you think that with this configuration, will the power be good or not?
buenos dias amigo, necesito de se valiosa ayuda, he visto varios videos suyos con respecto a estos dos transistores en particular 2sc5200 y dsa1943 ,porque tengo una bocina de 15 pulgadas que traia estos dos componentes y una alimentacion de 45+ 0 45- y cerca de los 2 transistores de potencia traia 5 transistores h649a x3 y h669a x2 y te pregunto si ¿este circuito aguantaría el voltaje que tengo ?para ya no modificar nada.
