Huntron Tracker HTR 1005B-1 Pulse Generator/Signal Tracer Component Checker

Question

Hi,

Recently I bought Huntron Tracker HTR 1005B-1 Pulse Generator/Signal Tracer Component Checker. But the transformer was no longer there(i guess that's why they sell it for a very cheap price). I try contacting the Huntron if by any chance i can buy a new transformer. Unfortunately, they no longer support the model I bought. Has anyone worked with this model before?

You could make a replacement for T3 ! It looks like a typical scope type mains transformer. You need to find out what the secondary high voltage winding is meant to deliver, careful reading of the serivece manual can get you there. The same winding makes 340V rectified and uses a voltage multiplier to make the 1350V HT. The AC voltage on the winding will be 240V. This will be hard to find, so I suggest you use 2 x 230V primary to 6.3V secondary type transformers. Wire them mains : 6.3:6.3:230V, you can take the fillament voltage from the mid point and the HT from the second transformer. If you use torroidal transformers you can tune the ratios by adding turns to one of the 6.3V windings, the first if your outputs are too low and the second if too high. You can easily add turns by winding some insulated wire around the outside (going through the hole of course,). I would be happy doing all this but if you don't have some experience with working with 1.3kV, fully understand what I'm getting at, and have some test gear (meter and scope with high voltage probes) then best leave it. Hope this helps, good luck. MK
