[Amps] Alpha 8410 using 4CX1500B - why?

[Peter Voelpel]

Funny, most TV transmitters in Europe with combined sound and vision
amplification have been with tetrodes in their final because of their high
linearity.
I never saw a commercial communication HF amplifier made in Europe with
triodes and all were designed for ISB.

Welcome to tetrodes Manfred. Very few are designed for very low IMD
