Rather than playing around with the bias, a small fan mounted on the rear of the PA cage, pulling air out of the cabinet is recommended.
There are several Fan installation articles posted on Ron's web page.

hi,
A long time ago I remember reading somewhere that bias voltage could be reduced so that there was no idle plate current between CW elements - the purpose being to lengthen the life of the 6JB6 tubes. I remember that the person who wrote that email pointed out that this would not work for SSB, but I don't run SSB on my T-4XB so it's not a problem.
I'm just wondering if this holds true or not and if it is advisable to run the rig that way, without idle plate current between CW elements instead of the typical 70 mils of plate current.
Thanks,
Jason
