Remote Balance Control: on Tube Integrated Amp?

Anyone know of a Tube Integrated Amp with remote balance?

Safe/Easy/External Bias control would be nice.

I find some individual tracks can benefit a great deal from minor balance adjustments. Especially compilations with many different engineers involved. Remote balance from listening position is the goal.

I now use my Chase Remote Line Controller remote volume and remote balance from listening position, as intermediary stage between a few components. Other sources direct to amp, no remote balance. It would be nice to have remote balance for sources that go directly to the integrated amp.

tubes, +/- 30 wpc is plenty for my very efficient horns. Using Cayin A88T 45wpc now (6550, KT88) Love it, except no remote balance. Used 35/30wpc mono blocks for many years (EL37, EL34, 5881), also plenty power.

Thanks in advance for suggestions,

Elliott
