YOU'RE the best! :angel:

Putting up an amplifier is hard job and you successfully set it up and also solved the issue in one channel. Credits to you for that.

Enjoy the silky treble, strong mids and truly punchy bass! It's the V4 sound brother! :)

Cheers :cheers:

Hi congratulations on getting your amp to sing. I am a bit foxed with the transformer voltage rating . Is it 42Volts after rectification or the traffo is 42-0-42 Volts in which case the DC output would be 42*1.44 = 60.48Volts.


Regards, enjoy the music...

Interested for the board, any available? This will be my first class AB build and I'll be using Exicon which supposed to be for F7 but seems enough class A.

I will build separate psu box with 2x25Vac and CRC filter, will it good enough for this vssa? i find many build with additional cap multiplier but i want to make it simple.

Yes it will run fine as long as the power cables between PSU and amp box aren't too long. vssa?

30cm cable with psu box is stacked below amplifier chassis, and i always add extra caps on the chassis.

I also have unused 2x15V 120VA toroid which I will also utilised later for another board, any estimation for output power? it wil power tweeter above 3kHz hence only small powered required.

i'll send pm for payment details

About 20W will be available. 120VA is ample reserve for >3KHz duty.
