One PCB to rule them all!!
This is the most flexible and comprehensive board we have designed to date. It can handle pretty much anything you care to build. Layout provided for a popular 100w ‘flagship amp’ to get you started.
Summary of options and features:
1) 3 channel with relay switchable front end gain stage
2) All fat, voicing options on the main board. Can be bypassed
3) relay’s for first gain stage, channels, cathode bypass/boost, clipping and fx loop
4) Power supply droppers and filters through to V1 (can be linked/bypassed of course depending on design)
5) Onboard rectifier, regulator and heatsink for relay and/or 12v DC heater supply
6) Zener or MPSA06 clipping options
7) Jump on / off pads for pre tonestack or post tonestack master(s)
8 ) Jump on / off pads for gain pot(s) position in circuit. I.e. José/BE style or 800 style.
9) Optional relay controlled dual global masters
10) Board will do a 4 gain stage plate fed circuit too
11) Clean channel, plexi style with its own cathode follower and tone stack.
This board was developed with feedback and testing from our FB DIY Builders Group. This board is ‘open source’ for layouts, many designs for using this board will be posted there. Search for #4gsbegenericpcb in the group.
