Wrongo Tom! The later models, (specifically the I model, which was the last)
and the when the government no longer needed them Bill Halligan returned the
old HT-4 label to them, always had an a 250-T(L?) modulated by 100-TH's.
The BC-610 was later replaced in military by the durable T-368 transmitter
which used a 4-400 modulated by 4-125's, (Not my choice, I prefer triodes as
modulators.). But they were never made with 813's or 833's.
