6G3 Deluxe style amp rebuild
Had a customer bring in a completely bodged up amp by some ‘boutique’ builder that looked worse than when I run pedal building workshops. The fiberboard was warped and messed up (shouldn’t be used anyway as it’s prone to leakage and isn’t designed for lateral insulation), the wiring made a dozen ground loops so it was noisy as hell, and the whole thing was just a complete clusterfuck.
So I quickly spun up a replacement PCB in Kicad and added some upgrades including a proper bias circuit, and separate grounds for each stage. I don’t care if people want to espouse the virtues of ancient tech that wasn’t good when it was new, I went and studied EE and there’s a reason they spend whole units on PCB design and best practices.
Next step, finishing up the wiring and moving onto testing.
