Just a word on ferrite beads, and other kinds of baluns. Trust us, if it
could be done wrong, we blew it, if it could burn, we burned it, if it
could be cracked, we shattered it, if it couldn't stand up to 1.5 kw, we
smoked it. We tried every possible short cut and cheep trick imaginable.
Anything except winding a special transformer that we couldn't buy
ready-made off a shelf somewhere. We got where we got because ultimately
only a rugged isolation transformer would get it done.
We are NOT opposed to your verifying our experience in that regard, by
starting with beads and working your way up. Get in a supply of
tranquilizers before you start. Only do one better than we did, take
pictures/video of the carnage for the entertainment of the masses.
The specific construction of the transformer stands up to brick-on-key 1.5
kw and runs cold. There is a reason for the low mu powdered iron choice.
