[AMRadio] 75TH vs. 75TL (was Class C stuff)

[Todd Bigelow - PS]

Speaking of the 30K series, I think we spoke about this a while back Brett -

What is the difference between the 75TH and 75TL? I seem to recall it was only a
different bias setting?

Also, with respect to the 30K-1 vs. 30K-5, I think the only difference in in the
PA deck - mod deck should be the same, so....is there an adjustment somewhere on
the mod deck for setting the bias on the modulators? How much of a difference is
there to use a 100TH instead? I seem to recall you saying that you ran 100THs in
yours....
