Nice project! I also like to switch the cathode capacitor of V1 in this way, which results in interesting variations for the sound of the preamp. Extra karma points for recycling old cases looks good! Real DIY.What is the range of possible output voltages of the HT power supply with the 20K potentiometer/trimmer?
