[QUOTE="KarlS, post: 214579, member: 2409"] C42 is a capacitor, not a resistor. As far can remember, After the mods to stop hiccups were done it was found that the SPP squeal for short time after being switched on. To stop squelling Reg recommended to short C42. Squealing has stopped but unintended consequences was increase in gain and sensitivity to small gold. And also increase in sensitivity to the noise.. Also I'm not sure if the mods were tested with every coil combination. From my patchy memory, setting the gain on 8 or bit less on modified SPP is about same as having the gain on Max on original SPP. Your problem with noise and lack of depth is most likely due to too much gain. I had removed C42 mod from my detector. Karl [/QUOTE]
