[Heath] LMO rebuilding....did I mess it up?

[Glen Zook]

The tube type LMOs are all TRW, at least that I have ever seen!  There are 2-different variable capacitors used by TRW and both types definitely need the braid added as well as needing to be lubricated again.  Both versions, of the tube-type LMOs are shown in my article on adding the braid at the following URL:

The solid-state LMOs that were used in the SB-303 and SB-102 have at least 1 additional manufacturer besides TRW.  The TRW LMOs were used in virtually all SB-303 receivers but the SB-102 had a lot of the non-TRW LMOs and, unfortunately, the non-TRW LMOs usually do not "track" very well.

 Ken,...and company...
 Oh, you can make it do just the opposite, believe me.  You can set up the cap to either start from fully open or from fully closed.  Thinking that the LMO would "naturally be set up to go up in frequency with indicated read out frequency" I set it up to start from fully closed.....but if it starts from fully open, guess what?  The frequency will go down as you turn the dial clockwise.....  Spent the hour before going to church reversing it and getting the spring loaded drive gear "cocked" and the braid back on...it should work right now...
