Two-channel 15-watt guitar full lamp

Today I would like to present the old structure in a new version. In 2012 I built a hi-gain based on a Fender preamp and a modified Mesa DR (Hellstone?), Which I called Angels? Massacrator. It was built so that 6N2P and ECC83 lamps can be used at any position. Each base has a glow switch. Two EL84 / 6P14P can work at the end, but also Polish TV PL841 thanks to the glow switch and the G2 grid. The design turned out to be unsuccessful, although some video from YT tests is: https://www.youtube.com/watch?v=4UMl-x9ajFc. What went wrong? Hard to say. The amplifier was getting excited, it could not be turned on full. He could even receive local radio from time to time. I couldn't deal with the problem and recently I took the preamplifier apart. He did it for about six months. My friend from Defil Repairman recently asked me if I had any 10-25W two-channel amplifier in stock. I didn't, but I remembered that I can actually have. Maybe not immediately, but rather quickly, because it is enough to add preamplifiers to this project. It stood on the classic, i.e. a two-mode Fender with a three-position equalizer and a JCM800. I got down to work and the effect can be seen in the pictures below. In addition to the preamps, an inverter was built from scratch and the power supply was slightly rebuilt.















Some videos from testing the version with the new preamp are also on YT.
