I am in need for a replacement of the Output Coupling wafer switch (SW6) that is used in the Valiant and I believe also the Ranger.  Position 4 has broken off (900 pf) and unable to repair.  Part # 22.1308..  If anyone has a parts unit and would allow me to purchase that wafer switch, it would be greatly appreciated..

Well sofar no soap on locating a replacement wafer switch for this Valiant.  All sources given to me proved unfruitful..  Somewhere I heard of replacing those switched caps with a variable cap.  Anyone heard of this also?  If so, can you send me a source for the info, incase I want to try this.  Hate to part out this old girl, even though she's been as faithful as could be over these years.  I have also heard of replacing that contact with another, but I dont think my physical abilities (shaky feelings) would make me a good fixer.  Just lucky I have another Valiant here that works great, so in no great hurry.

Why not try connecting the pin 4 connection to pin 3 and pin 5 of the switch? Unless I can't count correctly, the only effect on the variable loading cap would be in coarse position #5. Obviously, drilling out an unused contact and the bad contact and then remounting the good one in place of the bad one would also work.

You might try here to buy a replacement switch. It's on his list:

Hi Pete.... I had already contacted Gary there at TRS and he emailed me and said he didnt have one.  Well, I got to looking at that switch, even with bad eyes, and figured I could repair it somehow, someway.....and I did.... dont ask me how..... anyway it is now working fine....  maybe I as usual, 'jumped the gun', hi..... by the looks of the contacts, it looks like whomever had it previously was switching it while still pushing RF ....  not good... cleaned up all the contacts and resoldered the pins and is working okay now....
