Tube amp bias adjustment advice

@mmporsche 

you can get your hearing tested too... if you really are wondering

good luck

but I asked my GF and she said it sounds balanced when seated in the middle.

Yikes! Do you notice any hearing loss in other situations?

If I could post a picture it would be much easier but I don’t see an option in Audiogon

You can post picture via Systems page

I must have hearing loss out of my right ear because I noticed no difference. I will buy an SPL and verify but I asked my GF and she said it sounds balanced when seated in the middle.

An Online hearing test may help.

https://systems.audiogon.com/systems/6261 @imhififan thanks for the advice. The first 3 pictures show my room. Please notice the large opening above the left speaker. Anyone know if the room could be causing my problem?

You got the answer.. Don't ride home with the window down, there is all kinds of stuff, to help.. That use to really mess with my listening sessions.

Take care of your ears... Make a big ear for one ear.. really. Take your hat off, NO HATS... The chair back.., needs to be BELOW your neck.. 

NO Smoking, cheap tobacco, or weed. Gargle with warm salt water...

YUP, you know what makes a good mechanic?   One that takes care of their ears... and hands, ALWAYS....
