@@MirkoPavleskiMK : Sorry no it does not I build it and the result is really bad. There must be something wrong with your schematic if it works for you but for others not.
Hi, I build the amp according to your schematic but have a lot of distorsion. I need to put the potentiometer on very low position else my speaker is clipping. Any idea what went wrong?
You can probably use two separate tubes for such a project as well. Wonder how to calculate component values for other tubes. Maybe you can make push-pull also if two transformers are used in the output?
If this unit is using the Low Voltage Vacuum tubes developed in 1957 for use in car radios when the transistors of the day were not ready for prime time then the Heater voltage should be 12V and the B+ should also be 12V.
@@MirkoPavleskiMK Hello my friend, I was looking for a data sheet for a 7815 where the input voltage may be over 35 V. Unfortunately I didn't find any. can you send me a link?
I would like to try to build it myself, but I think that your schematic is not correct. The pins of the PCL82 are different in the datasheet, and your schematic shows the cathode of the pentode connected to +40V .
Много добре се е получило, браво приятелю🙌🙂
Поздрави от България🙋♂️
Фала :)
Hey Mirko, I built your design and it works great!
I share your video on my channel
Thanks, another proof that the amp works great

Very good audio.
Ne kadar çok ve güzel videolarınız var teşekkürler
Excellent project 👍
Vacuum tubes operate as a Class A amplifier.
If i use PCL81 will be the same ? because the kathode is common in the circuit !

Chapeau! Isnt there any noise from the dc-dc converter?

Hi nice project where did you get the transfer? Can you give me a link? Thanks for your help.
On your speaker it is written 8ohms 10w , why did you tell it's 3W 4 ohms?
Hi, your boost convertor board can give up to 60VDC , Why don't you try it? I think it will increase the output power.
Thanks for the suggestion, right at 60V you get a bit of power output
Muito bom o amplificador parabéns, bom natal para você e família saúde e paz. Abçs.
Thanks a lot :)
fun!

Did you really think 40V input for a 7815 is o.k.?
yes, it is ok

@@RalfWeber-tb3my max input in my Pdf is 30V!!!

Pin numbers are correct, bit pin 7 is G2, and 8 is kathode of pentode. The inside of the tube is incorrectly drawn. Sorry, my mistake.
I'm just starting out in tube electronics, so are these connections correct 4:00 ? Thank you.@@MirkoPavleskiMK
@@dx835 Yes, just don't look inside the tube, just connect the pins according to the given diagram
@@MirkoPavleskiMK Thank you for the clarification.
This is really an advertisement for pcb way!
7815 - 40V???
Yes, the 7815 has a 45V input limit
