Capacitors with values < 1nF are MLCC, values of 1nF – 1uF are SMF (except C15, which can be MKT)
and all values > 1uF are Electrolyte. P1-P5 are 16mm Alpha pots (A=log, B=linear, C=rev. log) , VR1-
VR3 are 6 mm trimpots.
All parts must be rated 25V+
* The Throbak uses an internal pot. Use a Alpha 16mm (external) or a Bourns 3296W style (internal) trimpot
** See the
Biasing
section for options before choosing to solder the trimpots!
