*Values should be precisely matched using a Digital Multimeter, in particular Capacitors, Use 1% Resistors for a closer
tolerance match. Capacitors have a wider tolerance, typically 5% to 20%.
** Silicon or germanium diodes will produce different sounds, with different circuits. Socket and See! If you have a DMM
or circuit, capable of matching the forward voltage, it is preferable to do so.
