GK+4 Probes

Bought the GK+4 from Atomic Dave in California. In these pictures, the GK+ is on the left, then an LND7317 pancake probe, mesh window up, then the LND712 probe that came with the detector, and finally, the small ABS plastic box containing an SBT-11A rectangular mica window Russian tube. This last is home-made, so the rectangular hole ins't precision.
Inside the Geo style aluminum box with the LND7317 is an anode clip with a 4.7 megohm anode resistor. Inside the LND712 probe is a 10 megohm anode resistor. Inside the SBT-11A is only 1 10 megohm anode resistor, though it was recommended to connect with 3 4.7 megohm resistors on the 3 anode pins. I gave up on that. Can't solder resistors to spring clips worth a darn.
