[Hallicrafters] HT-32 PTT and runaway in finals

[psturdivant n1ps]

I'm back to the list after a month or so after changing email.

Hello again.

Anyway, I'm getting ready to get my HT-32 on the air, mostly as an AM set.
I'm considering adding remote PTT so I don't wear out the Operation Switch.
Has anyone tried this?  I noted  the PTT relay control, V17B, is enabled
with a contact closure to ground.  This could be mimicked via a remote PTT
switch like a pedal, after reviewing the prints..

Has anyone tried that?

Also, the finals on this set occasionally go into harmonic runaway.  I'm
replacing the finals when some new ones come in.  Then I'll neutralize the
finals....

Has anyone seen a similar situation?  This xmitter uses plain 6146 pentodes
(and I'm staying with the same tube...not the A or B).

TNX

Pete
