Hello my name is Michael and I am a fan of tube amps. In the past I once built an EL84 push pull but unfortunately it went up in smoke. Currently I use a Classic no 9.0 tube preamp and 300B mono power amp. I also own a Prima Luna Proloque Four EL34 power amplifier. I made some improvements to the Classic such as lower glow voltage (it was too high) and grid stoppers to prevent oscillation in the amplifier. I also use many oldtimer speakers from the Translator brand: http://www.translator-info.nl I learn a lot from Skunkie's videos. I'll post my schematics of the amps I own in the other threads. Here a picture of my mancave 😀
