An Archaic Behomoth perhaps, but the first exposure of Signal Corp students to transmitters and whose basic MOPA configuration today has gotten new life by Mike's infusion of the appropriate new cylinders and ignition systems for years ahead performance pleasure. Nice to see a systematic approach to objectively assessing  the nature and idiosynchrosies of the system and make the appropriate changes within the parameters for the basic configuration. As to the note regarding care around  the high voltage, use of the BC-191 functional training aid shown in the attached picture was an experience all by itself. Looking forward for the completion of the saga and establishment of the BC-191U , or updated configuration.

The 191 sounded very good on the air today Mike.
It started out a bit rough and FM'ing but cleared up after you did something.
It sounded quite good, just the audio level was a bit low maybe, but little to no distortion and the audio even had some nice low end.
A very nice qso.

Well I submitted the whole saga in an article including pictures and schismatics to Ray and we shall see if he decides to publish it!
