Hi Bob,
    I agree with your reasoning and have done it that way on several radios,
incl the HT-32, that were "backwards".   I'm sure there was some reasoning
behind the original, but don't know, maybe it was different colors back then.
    On your bias supply issue, the original selenium rectifiers often developed
a high voltage drop.  I used silicon in the HT-32.  Never heard them being
blamed for the common power xfmr failures, have heard cautions to pause in the
stdby position before turning off, to reduce spikes.  My HT-32 has a nice Peter
Dahl xfmr that the previous owner had bought but not installed, after failure.
