I connected the loudspeaker to check if the music was flowing from it. The amplifier works !!! I hear the music!!!
I'm exhausted.
Now it's evening at my place, I can hear the rain outside. I think I'm going to do what I want...

I replaced all the wires, replaced the capacitor C11, C10, returned to the 12w resistor R22, also replaced the L2 choke. Now I sit for over two hours next to amplifier, just like sitting at the bedside of a sick loved one person.
Nothin...

I ordered new wires and ordered a new multimeter. Maybe mine is faulty. This is Chinese, not very expensive equipment. I will replace all the wires in amplifier and measure everything again with a new multimeter. Fu.ck....

I made this measurement in such a way that I unsoldered the wire from pin 4 (black in the photo) and connected to it the red clip from the multimeter, and to pin 4 I connected the black clip from the multimeter. I set the multimeter to the mA rea...

5hours pass when I sit in the chair and stare at work of my life (amplifier), like some haunted man. As you can see, I divided the amplifier into two parts, the power supply is in a separate housing. I d...

Hello Dima !!!!
At point D I have 0.920 mA ... at 198v on pin 4. 238v before resistor R22 and 200v after resistor R22. On pin 5 I have -82. There is 82mV across the R21 resistor. I noticed that when I turn the VR2 potentiometer, thus inc...

Is 88mV.
I also noticed that resistor R2 is also very hot ...
Can bridge rectifiers have any influence on all of this?
...

Tr2 is 100Va Tr3 is 120Va. 508v is at the output of the transformer connected to the load. I also measured tube heaters. The 6c33c is 14.2v and the 6e5p is 8.6v. I will not hide that I spent some time staring at the glowing tubes, with only the h...

And this capacitor is connected as shown in the photo. its minus goes to mass, its plus goes via R21 to the B + tap in the OTP transformer. I waited for the resistance to stabilize, which started at 2 million ohms and stopped at 42 million ohms ...
|
|
And The first thing I did was I grabbed the multimeter and started measuring what JJ suggested. I think we're on the trail of "something". I discharged all the capacitors in the amplifier and with the amplifier turned off, when I put the red tip ...

Or whatever you call it, it says there is no sucha option that I make a connection error, but hey..., I'm 41 years old and I know from experience that sometimes this voice is wrong ...
As I mentioned, I am not in the apartment at the mo...

Because I feel that with your help, sooner or later I will solve this problem. So far I have been feeling very frustrated for days, so I decided to post this on the forum as a last resort. I do not know any people who know electronics constructi...

I mentioned earlier that this is my first electtrical device that I build. Realizing that it could be dangerous to my health and even my life ... I planned and soldered all the parts for a couple of months. I know every connection and ever...

Anthony,
First of all, I would like to congratulate you on making your amplifier. I have been following your build from the beginning and now that I am building my own amp, I appreciate your work even more. I admire your plan a...

Romy,
I know you are busy building new speakers at the moment, but I have to ask for your help.
I started putting together the full range melquiades amplifier. This is my first time building any electronic device, ...
