Context I've been doing a deep dive into pedals for the past several months. One interesting observation I see is the dominant prevalence of PCB's as the construction method. It makes sense. Lots of advantages. More efficient use of space. Easy to work with in a paint by numbers approach. PCB mounted pots are super nice to hold the board securely. But it isn't just that PCB's are commonly used in pedals - but I'm shocked at how vast the library is. There are a handful of different vendors selling PCB's for just about any pedal you may have or haven't heard of. They sell the PCB and you source the other parts. Next enlightenment is that one can readily download software to draw schematics and then transfer that into creating a Board layout. The software will perform some design checks to ensure the board is within construction tolerances at a real life factory. Then you can send that file to a variety of factories in China that will make you a PCB and mail it to you. For like $20 for a set of 5. So I'll get to my question - why aren't PCB's used in the DIY amp making world hardly at all? Almost all builds I see are Eyelets or Turrets just like Leo and Jim used to do it. Some PTP-ish work from time to time. You see PCB's commonly used in amps made at scale in factories. But I would also state that there are a number of higher end builders that use PCB's in their amps. So I don't think you can argue that a PCB can't make a good amp. The Argument Against On the other hand I can see why they aren't used as much. In amps you don't have as much premium on space conservation as you do in pedals. Even with a PCB you still have a fair bit of off board wiring to do. I would say that amp building is more advanced than pedal building. It requires more safety, more knowledge in construction techniques, more expensive components. There are probably more people building pedals than amps. Pedal guys can build up a stash of parts and basically order a PCB on a whim and build it from their reserve without a lot of problem. One element that I waffle on is the aesthetics. Some of you guys make works of art - and the use of a PCB may detract from that. From a design perspective I can see some negatives. You need more care in thinking about ground planes, trace routing, and component locations with amps compared to pedals. Pedals are also easier to prototype. The Argument For All that said, I don't really think there is a good reason why we in the DIY amp building community don't use PCB's more. I think it could be a great asset for the newbie. Take a PCB and combine it with thorough instructions and it really makes it a straightforward paint by numbers approach. If you could find a way to mount tube sockets directly to the board and handle filaments too - without noise or other design issues - it would be VERY beginner friendly in my estimation. Next it could give a more aspiring builder some nice options. Thinking about if there was a web store like some of these pedal pcb stores that offer a pretty wide variety of PCB's and then you source your parts around it. Not as a kit, but just the PCB and the rest is on you. Many guys in this forum would easily be able to tackle some pretty advanced circuits if enabled by PCB. Next I wonder if this is simply an area where we are simply stagnating. This isn't the first time guitar players have exhibited some ludditism. I say this to myself as much as anyone else. Conclusion So I would love to hear some feedback. Have any of you guys messed around with PCB's in the DIY amp world? Are there reasons I'm not contemplating?
