Q: How do you plug a tube amp into a breadboard?

A: For small tubes, this problem may be circumvented by directly soldering short lengths of 22-gauge solid copper wire to the pins of the tube, thus enabling you to “plug” the tube into a solderless breadboard. Here is a photograph of my tube amplifier, showing the 12AX7 in an inverted position (pin-side-up).

Q: Can you touch a circuit while energizing the amplifier?

A: WARNING: do not touch any wires or terminals while the amplifier circuit is energized! If you must make contact with the circuit at any point, turn off the “plate” power supply switch and wait for the filter capacitor to discharge below 30 volts before touching any part of the circuit.

Q: How to fix oscillation in tube grids?

A: The input impedance of a tube grid is already extremely high, so adding some extra resistance doesn’t effect the operation of the rest of the circuit, but the grid stopper acts as a lowpass filter with the grid’s Miller capacitance, further hampering high frequency noise. Together, these two fixes solved the oscillation issue.

Q: What is a Hoffman board?

A: Hoffman boards are classic amp circuits that have been re-designed using my own turret lug layouts. I didn’t invent the circuits, I just came up with a slick way to organize the circuits on super neat turret lug boards. Hoffman Turret boards are 1/8th inch thick glass epoxy material.
