Ok thanks.

Welcome Sir....I use shielded because it is an AC run.....

 

[laatsch55]

Caps wired in, neatened up and headed east....

 

[laatsch55]

Thanks for the heads up, Gepetto!

 

[laatsch55]

Heatsinks on and outputs in, DCP wired up...

 

[laatsch55]

Right side done...

 

[laatsch55]

Time to power up....

 

[Justin Case]

I'm listening!

 

[laatsch55]

Work interfered....power up tonight.

 

[Justin Case]

Work interfered....power up tonight.

As a pirate said once, "ARRRRGH!"

 

[laatsch55]

Amen Steve, tantalizingly close....

 

[FredR]

Work interfered....power up tonight.

Shame that things like making a living have to interfere with our hobby.

 

[laatsch55]

Amen Fred.....


AHEM......power up did not go well......D12L, D12R were put in backwards, AND R11L, and R11R were not even put IN THE BOARD....without R11 in, there is minus voltage about anywhere you want to take a measurement Except on the plus rails....Jeez



All is well now....Offset is .001 on the left, .000 on the right. Bias dialed right in...it will be on the AP after breakfast....

 

[laatsch55]

I would like to say I had been interrupted a dozen times with emergency calls from the field when I put that board together, but NO....it was during a time when it had my complete attention, absolutely stress free assembly time....so....no excuses...I just F*&^%$ up....

 

[laatsch55]

Resisual noise is KILLER!! 157uv on the right, 173uv on the left...
