To do this I need to solider in the Aux amp and vibrato circuit. I have most of the transistors I need as well as the Vactrol LED/LDR cell I need for the vibrato circuit. However I am having trouble trying to figure out what the values are of three capacitors in the Vib circuit. They are the same capacitors shown in your wurly vib schematic at the beginning of the blog. They are C16, C17, and C18. The service manual as well as the schematic displayed on this blog show non-polarized caps with .12 value assigned to them. But the .12 does not have a unit value attached to it such as MFD, µf, or pf. So do you or anyone else know what the units on those capacitors are!!!! Any advise would be greatly appreciated.
