Yes, and this is how I did it. I bought a pair of I.A.G. TVC's which use Sowter transformers when I had Paul Birkeland build my Sister/Kugelis Linestage back in 2005. I auditioned it in Doc's big system at BH and did not find it lacking in any way. These TVC's have performed flawlessly ever since, giving me 27 steps from the Shallco switches which are quiet and high quality devices.
In the version Paul built, this Linestage uses EL84 current-sourced 6C45Pi tubes to drive a pair of MQ B7 Cobalt core output transformers with V-cap TF/TF caps. I include a couple of pics to show how PB implemented Doc's original circuit. The hybrid shunt-regulated dual power supply was designed by Paul Joppa, and utilized his latest thinking at the time. The Linestage is dead quiet, and it has plenty of drive for any headphones from the front panel output.
Cheers, Hank
