Are you ready to face strong emotions?.. Dx Blame MKII and the Supercharged release!

Uncle Carlos and Andrew T

Thank you for the suggestions.

It seems the problem was cold solder joint
I resolder everything.. remeasured dc offset .... -0.6 mV and 2.3 mV

I'll test the amp with a 8R dummy load

Happy New Year to all.
Wishing you all the very best

I am glad to know that.

Enjoy your amplifier.

be happy,

Output coil..... i have made tests with a different output coil and resulted good

Internal diameter - 5 milimeters
External diameter - 7 milimeters
Wire diameter - 1 milimeter
Coil length - 17 milimeters
Number of turns - 15 plus half and plus half...this represents 16 turns

Inductance - aproximatelly 0.692 microhenries (692 nanohenries)

Resistance in paralel was increased to 15 ohms, 18 ohms or 20 ohms / 5 watts... can be a coiled wire resistance.

During tests i have used the coiled wire resistance of 18 ohms and 5 watts...some inductance is provided by the resistance windings.

Blue boards have holes into the coil position, that accept 1 milimeter coil wire without problems.

Carlos

FAA, from which part of the Philippines are you?

This chart helps a lot

Carlos, I just took a look over the updated web site. It looks good, and the pcb work is outstanding.

 

[destroyer X]

Thank you Bigun

I am waiting some parts boys.... some parts installed will be substituted

by others...more watts in some resistances.... and other details...insulators was missed too... bias trimpot and other things.

I have just made the metal work (boring)

regards,

Carlos

There's an error into the Supercharged bias circuit

R20 should be increased... watch here:
