If you are not 100% with resistor colour codes use a multimeter to check values as you place the resistors
Chart of variable parts
RPAD Normally = 120R but can be made smaller in value for greater than 20dB PAD or larger for less than 20dB PAD
RLoad for JLM14 = 2k2 and Z pot 50k (front & back pot legs joined), for VTX = 10k and Z pot 100k (use back pot legs only)
CLoad can be not fitted or up to 390pF in value depending on the opamp used has stability problems.
Ratio Pads not used for JLM14 or VTX leave blank. Only API2622, JE-115 etc
Phase pads These are only needed/used if fitting API2622, JE-115 input transformer etc.
