Can I tweak L-R balance by differntial biasing?

All- sorry about the misspelled subject.
Zd542- I thought of that but desperate times call for desperate measures ;-) Also I was thinking about only going from 0.20v nominal to 0.19v. So far the bias seems rock steady so I might go to a more sensitive scale on my VOM and try going up 0.05v on one and down 0.05v on the other. I realize that the differential is the same but...who knows. I readily admit my technical ignorance so i thought i'd throw this out there any see if anyone has ever tried it.

Al- Thx, after thinking about it more, I began to believe that the approach, which would limit the power output, would not have much effect at typical listening volumes, but I do not have the technical background to be sure.

Rrog- If my integrated amp HAD a balance control, I surely would use it. Re-arranging the furniture is not a viable option, it's OUR living room and my wife has compromised enough by having one end of it full of my gear.

Atmasphere- Well, that pretty much settles it ;-) Missed seeing you in NY this past weekend. I imagine exhibiting in NY must be very $$, but the show could have used another good tube set-up. Too many uber-detailed, unmusical, megabuck ss rigs.

All- Sometimes, thinking outside the box is thinking outside reality. Case closed, bad idea. Thx for your help.

Mezmo- Great idea. It works!!!

Don c55- I had not thought of that. I do have 10 dB Rothwell attenuators. I'll try that but I believe the difference is not that great.

Atmasphere- well, then it's pretty scary that the manufacturer or distributor put a comment in the biasing instructions that said it would. I guess you can't always believe everything you read!!! Another illusion shattered.

Thx, Ralph. Again, really frightening that the Bias Measurement and Adjustment Instructions include the following statement (and I quote) "The voltage is 0.20V. Low voltage settings cause output power down by well for the tubes life". I don't mind the translation issue but from what I've read above, it sounds like the information is incorrect. Or perhaps it's technically true but not relevant due to it having only a negligible impact within the "typical" range of underbiasing???

Thx, Atmasphere.
