Yes, I certainly do NOT recommend this solution to anyone else.
As I myself work with tube amp for quite a long time now (repair and mod), I can classify the risks involved.
The earth Connection via the connected equipment remains, and besides the DC B+ voltage form Tube amps, the 240 VAC from any power supply remains enough to fry anything, unless you have fast fuse protection - and or Fi guards.
2. concerning the hum isolatores , yes I Isolated one preamp completely, the reduction in hum was evident but certainly not 0.
In terms of sound quality I can only speak in the highest regards from Lehle.
So far, they are the only ones where Idid not perceive any sound degradation. Even the famous AMP switcher by Mesa Boogie with top notch
Jensen transformers did not live up to the Lehle.
So far I consider my issue solved (for the moment). Stiil I'll pursue the quest for solving the taped earth issue.
