2xGU-19 ( ГУ-19 , ГУ19 ) CB linear amplifier by YO6PMX

A few years ago I've built a CB /10m linear amplifier using one tube GU-19. The results were good so I started to think that It might be a good idea to build a 2XGU-19 linear. A few weeks ago the opportunity has come. I am using a "classical" schematic from PA0FRI's site https://pa0fri.home.xs4all.nl/Lineairs/Frinear150/fri150eng.htm , just that I am using 2 tubes instead of one. The diodes from the 2nd grid multiplier had to be replaced with 1N5819, the 1N4148 cannot handle the current required by the 2 tubes.
The results are good, almost 400W can be obtained in avg mode from this amplifier.
