Olsen KB 141 RF Signal Generator & Tracer

Post by MrBill on Wed Mar 19, 2014 7:22 pm

So I have aquired a NOS Olsen KB 141 never assembled. I will install new resistors and capacitors but my question is what type resistors should I use? I have read that 1 watt flame proof with 350 volts or higher are recommended.
Also should I consider adding any auxillary jacks so I can add a frequency counter? Im new to all this so please be gentle.  Smile

I may be wrong but I would check the ohms of the resistors. If they were what was on them I would use them. As far as caps I would replace the wax caps. I am not sure of how old that is but if some of the caps were the epoxy dipped orange drops or similar I would use those as well. As far as replacing the resistors if I had to I would look at the assembly manual and get the equivilent or better ratings on wattage.

Make sure you have the probes.

If not, on the RF output (if you have room) Replace the RCA receptacle with a BNC and us RG 59 cable and make your own probe. I haven't seen any instruction manual on the web but always use a blocking capacitor and attenuator on your own probe to project your signal generator from DC voltages.



You can put this in a small tin metal box, and then use a BNC T connector to hook up your frequency counter. You can make it elaborate or simple.
