The Very Best Amplifier I Have Ever Heard!!!!

[megaohmz]

How did this guy naggysaudio get banned? Just curious.

 

[Bonsai]

Very nice work Mr. Alex MM...very good...

Let me second that. Great work Alex.

Let me second that. Great work Alex.

like telos diy

 

[alex mm]

..... thank you to all

 

[Marko25]

Can someone post the completed circuit that they have tested and made for completion purposes? Thank you.

Hi,

Can I have the schematics for this nice fet amp.

Thanks,

Dennis

Hi Alex, just curious but why did you make a second one, was the first that good. How do you rate it subjectively to your other favourite amps?

Good job Alex
BUT this amp suffer on VAS stage 72 degrees Celsius with temperature room 31 degrees Celsius
Τhe next day i will show a new way to hold the transistors with clip to a larger cooler 52 degrees Celsius.
Regards Nikos

Hi Luke ,
I have, for free two PCB's from a friend ,and 6 laterals N and P (I bought 10 pairs of EXICON's)left from my last project , so I have built the second amplifier with better parts . I like the sound , warm close to tube amplifier . I have also built 2 Grommes A260 modified PP amplifier with russian 6P3C and GU 50 tubes . Ultimately the sound depends on the speakers
@nikosokey
thanks for your comments , I will mount a bigger heatsink on VAS transistors.
Yes, you right , they are hot ......

regards Alex.

Nice power switch , what's the source of it?

Hey, Alex, did you make those cuts on the board, that have been discussed ealier on this thread or elsewhere? Or did you use your layout as is?

New way to hold the transistors with clip to a larger cooler 52 degrees Celsius.

That's some out of the box thinking that I like. Not the most pretty but very practical. Nice work.

Mark.

Unless I have missed it reading back through all of this, what is the pcb layout for the power supply?

Thanks,

Mark.

Hi Alex,


Good Day. Can you provide me schematics for this amp?

 

[Mikewong]

Could I use a pair of 500VA-220V/60V which I have with primary in parallel connection and the secondary in series to obtain +-84V DC in this project?

 

[Mikewong]

I have two toroid transformers with the same rating 500VA Primary 220vac/ Sec 60vac.
Would this connection safe or dangerous?

 

[koldby]

AndrewT,
I believe you misunderstand him.
He has TWO transformers , each with a 220V primary and wants to parrallel couple these two transformers and then series couple the secondaries from the two transformers.
As long as the phases is the same for the two secondaries , this is ok as far as I can see..

yes, you can do that, just get your secondaries phased correctly....

 

[TonyTecson]

and where did mikewong ever said he that he had 110/120vac winidngs?
