What’s up my friends, welcome back. Now remember that my previous post on vacuum tubes amplifiers was with a low power one. Actually, that was a so-called pre amplifier. It was only adding the harmonics effects but the power output wasn’t high enough for a speaker. This time we will make a bigger one. I’ve bought a kit from AliExpress and today we will check the part list, I will try to make the schematic and then we assemble it and test it out with some speakers. Let’s see what we need.
