Shack cleaning--A while back I came across a small quantity of the R390 green gears reproductions that I had squirreled away. I believe someone in the R390 community had these fabricated to spec perhaps fifteen years ago. I'll offer what I have at $4/ea plus $1 U.S shipping, but please limit of one to help spread them around. Note: These are useful/necessary for working on the R390 gear train, but are not applicable to the R390A series.
I also have some very nice Xicon 82 Ohm 5W resistors that can be used to make excellent 3TF7 ballast substitutes. A pair these in parallel provides 41 Ohms resistance, and ample dissipation for dropping ~12.6V @ 0.3A to the oscillators. Just add another $1 if you would like a pair. Plenty of these available so no problem if you need extras.
If interested please contact me directly off list at bryanste..at..yahoo..dot..com
Thanks
