This is a Marshall JCM 800 2204 copy. It it true point to point and has Telefunken ECC808 pre amp tubes, a significant upgrade over ANY 12AX7 preamp tubes. They are quieter and less prone to microphonics yet have the same gain. The cleans are sweeter and the over-driven marshall tone is even more intense.
Notice the point to point wiring direct and concise as possible to reduce noise and oscillations. Note the resistors all 2 watt metal film, again to reduce noise. See the layout , neat and clean, even the tubes are turned with the plate end grids aligned to keep the signal path short.
