I wired the mosfets following the schematic not using my design as they were just there for demonstation. Checking again now just to make sure.

If you are facing the part, the pins would be gate drain source, from left to right.

Like so right? then it should be fine. However, i spotted a mistake on my board, a jumper that wires the Drain to power is not placed properly,  however the other channel should be ok... Yet nothing.
 
EDIT: Fixed the Drain and fixed one tube wired wrong... man I know I should have went to bed instead of trying to rush the build. Hope nothing is blown. Still no sound
 
EDIT: PSU running at 65Volts... What is going on...

 

[digger945]

Check some voltages. Start at the power inlet.  Make sure the polarity is not reversed.
My first guess would be cold solder joints.

Could you indicate on the design some useful place to probe for voltages? I test for conductivity after each solder joint I make.

 

[digger945]

how about pin 4 or 5 on the tubes. One should be about 12v and the other should be zero.

Any tips on how to add some LEDs under the tube circuit wise?
 
Also:
 

 
Case need to be varnished and the external components needs to be soldered in, I should be done sometime today.

You are not finished in this pic? It looks like nothing connected to pin 1(plate) and a wire going to pin 9(should not be a wire on pin 9)
 
Up close pics would help.

the tube sockets are wired backwards. 

 

[TestSubject]

All right, here are some pictures of the sockets.
 
EDIT: I read about 17Volts between pin 4 and 5
 

 

 

[digger945]

Nikongod is right. The sockets should be wired looking at the bottom of the tube. They are backwards.

 

[TestSubject]

All right! Thanks, is this a standard way of laying down pinouts?
 
Soldering iron heating up.
 
Hope this works.

 

[digger945]

Yep, wire according to the diagram you posted earlier, while looking at the bottom of the socket.

OK Well i am pleased to say that I can hear sound! We are getting somewhere. One channel is louder then the other and i can hear a buzzing sound in the background. I have tried to switch the 2 tubes but the same channel is louder. Could the Buzzing be cause by the PSU? What could make one channel not as loud? Looking back to my first Cmoy amp the same thing happen when a capacitor had been damaged. hope it is not the case here, none of them are swollen but still.

 

[digger945]

Check some voltages and compare the 2 channels.
 
Power down and check the resistance from input RCA jacks to the grids, and to ground. Again, compare channels.

One Channel measure 19Volts between pin 4 and 5 while the other 27 Volts... Checking board now, probably a resistor right?
