Well, it has been tried, with no success. Could be that then the tubes were
used and had little emission left as they were pulls from FM transmitters.
A new tube might work. But 170W i a 'lotta' drive for no reason.. the TS930
only gives 100W and with that I now drive the DAF amp to lovely numbers. So
the drive power shows up as output in GG, not an issue here..
Murphy was right.

Ciao,
Peter
