Provide some images and listening notes. Did you stick 100% to the component suggestions?

with an 8 ohm 10w resistor across the binding post I get 0.0mv :wine:
thanks so much for the help, onto stabilizing the bias

Wihout load seeing 14v at outpu is normal.
The proper way of fixing this is to connect a resistor 1M ohm at the output. I would recomend any 1/4w resistor or larger with 100k to 1m resisance.

Without any resistors connected to ground at the output, the output is floating and the voltage will be unkown.

I've seen this plorbem with one of my pre amps, during testing no resistors are connected at input, the input goes through capactor to amp. I was seeing a few volts I thought something was wrong.
Once I connected a 470k at intput instantly fixed the plorbem
