Hi Crazy Sam,   Have you looked at the voltage (DC) on R1E and R2E?  If the DC offset is high, the relay will not trigger.   If the relay is clicking without ICE (TL081) installed I would think that voltages to the relay are good from LV+E.   What voltage to you have on v- of the TL081...

Crazy Sam,   If you are installing them on the top-side of the board - then yes - the printed side with the three dots will be facing away from the heatsink and you will use the mounting position towards the front of the amp (towards the tubes).

In the event that anyone else reads this post - I found the problem.   Continued checking all components and found that I had installed 4.99K resisters in R12L, R12R instead of 4.99Ω as needed. D'OH!   After correcting my mistake everything is now working as it should and the amp sounds great!

Running into problems with the initial setup/start-up and I can't find the cause.    Amp has all the correct (very close) voltages before strapping jumpers J1 J2 and J3   TL+ = +15.14 TL- = -15.20 TH = -12.36 TB+ = 128.8   After strapping J1 and J2 I don't have any voltage on R10L or...
