Default my zen test

Hi

I have just powered up my Zen amp ,no buzz no hum.
this is my first build on a home made board
My transformer is 25v /25v and the voltage at the power in is 36 volts each side

voltage across r1 is .66v on left and 1.4v on right
My drain voltages are 4.8v left side and 5.5 right side
o volts on the output
The only things I can think of are assembly problems the board the 10k pot ( very small from maplins ) and the P1 tight for space
so I plan to rebuild on a bread board or a better made board .
I thought I would post these results to see if the the solution may be obvious to a more experienced builder .

Also is it still possible to by a pc board ?
Thank you
Mark

Hello Mark, Here's the link to Old Colony Sound Lab in New Hampshire, USA. The specific link is for the page where they list ZEN amp PCB's.
