Re: Marlboro - Quadra Sound Blender QBS [schematic]

Schematic time: Preamp.JPG Reverb.JPG Tremolo.JPG Thanks for schematic, really appreciate it :thumbsup I also have Marlboro G-50R. It's wonderfull sounding amp, but it's a bit noisy when I turn it on. Is it problem with old capacitors, maybe amp needs recap? Do you solved that problem with your amp?
