Guys,
First why every use something that not what it is. In college we were taught to investigate parts by what it was designed for and that would tell us how best to use it.
Using a pentode as a triode is just silly. That's why they made triodes so you didn't have to muck with pentodes.
UL is not a good idea for SET's, its way to noisey and mess up the direct current flowing through the output transformer. What you want 1/2 the transformer to see X amount of current and the other 1/2 to see 120% of X??? Not a good idea...
SET Pentode should be just that make the damn screen regulated at some set place and you will have better output.
Thanks,
Gordon
