At the same time as @theprofessor was getting on board with the out board Surfy Bear Reverb, I found myself ready to finally take the plunge and go with FETs over tubes. Seems like @SebC was in the same boat. Surf’s up folks! It will take longer to make the enclosure—white tolex, blackface control panel, and wheat or DRRI grill cloth, than complete the actual circuit. I’m testing this switching power supply. I think there’s going to be too much noise, so I might need to go linear (the input and the foot switch jack location in particular). Thoughts on this welcome. A member of the SurfGuitar101 forum used a similar power supply with no issues, but I’m not sure where they mounted it in relation to the the SB circuit.
