| Project Notes Stay tuned, more notes to follow as I think of them. Here's the updated layout diagram for tube pedal pedal #2. |

 DC voltages are listed in Purple |
#1 tip: Space is very tight. You must plan everything very, very, very carefully. I ended up removing the relay from my project. Reasons: Space is really tight inside this chassis. Relay coils too close to input jacks produce more hum. Longer signal wires leading to and from the relay add hum. The pedal is now dead quiet without the relay. I don't turn off the hot switch mod anyway. I would think twice about using the foot switch to switch any signals. I would use the switch as power on and off and keep the signals all at the other end of the chassis. Keep your power transformer, bridges, voltage regulators far away from your signal. Note how I have all the power supply stuff on one side and the circuit parts on the other side of the tubes. Mount the 7812 voltage regulator on the chassis next to the power transformer so that the chassis acts as a heat sink. The voltage regulator gets very hot. Cut your circuit board 3 3/4" wide so that it fits between the bent over edges of the back cover. I used 5/8" hex standoffs because the Illinois 22/500v caps are 5/8" tall. Taller or larger filter caps would not fit under the board. 5/8" standoffs work perfect for tube height. I changed the cathode bypass caps from .68's to 1uf's because the .68's would not fit under the lid. I blocked off the LED hole by the footswitch on my pedals because they are right where my filter caps are. |

| This is tube pedal #2 using the circuit listed above. Note that the circuit board is way smaller than tube pedal #1 and the components are wired point to point to save space. On the back of the board is where the filter caps are. 3-22uf/500v filter caps and a 4700uf/16v for the 12volt supply. | |
