Hermansson 3 gain stages circuit in a Marshall 1987

I've installed the Hermansson 3 gain stages circuit in this Marshall 1987 from -74. It's an all-tube distortion circuit, no clipping diodes or transistors.
Other features:
• Punch control
• 3-way preshape switch
• 3-way punch range switch
• 3-way presence range switch
• 3-way bright switch
• 3-way mid boost switch
• 3-way dark switch
• New ground layout and preamp shields
• LND150 based effects loop
Guitar straight into the amp, TC D-two in the loop, cab is loaded with Greenbacks.
