Layout and Lead Dress:

Since layout and lead dress are vital in analog circuits, a great deal of attention was given to the placement of key components. No detail has been spared. Signal leads are kept very short, to minimize both magnetic loop area and capacitance to other wiring. On the signal return loop, ground connections all return to a low impedance ground plane.

Grid stopper resistors are used on each vacuum tube grid, to damp any resonance associated with grid capacitance and lead inductance.

High current heater wiring is elevated from the circuit board on heavy gauge shielded twisted pair wire.

Experienced craftsmen assemble each preamp by hand with loving pride. We treat every unit as if it were going to be hooked up to our own system.
