I'm familiar with that rig - the BCA-5T as I recall. If you mistuned the harmonic adjustments, it was a 3500 watts AM transmitter. When you properly adjust those harmonic cranks, it did the full 5 kW AM. Seemed to work fine, very interesting idea. It wasn't the absolute best-sounding 5 kW you could have, but efficient.
