I said I wasn't going to build another linear amplifier, but the call of valves that glow in the dark was just too strong! 🤣

This project required two NOS Soviet era GU-13's (813 equivalents), run in grounded grid configuration.   75W in gives 750W out, so a gain of 10dB. Harmonics are down -54dB on the fundamental. 20m 813 Linear Amplifier.  20231115
