TDI SL Modifications I Haven't Seen Before...
I came across a french prospecting website where some interesting mods had been done to their White's TDI SLs.... for instance:
1. Removal of resistor R86 within the gain circuit - providing a boost to the gain control. They believe this was to make it stable, for less complaints. Removal of this resistor provided additional gain reserve. They had some good results with their testing.
2. Placing thick o-rings under some of the pot knobs. Helps to add some friction and avoid dials t
The 16V limit applied to the TDI, some people probably assumed the SL was the same. They are different designs. The FQT7N10 are FET transistors, used as reverse battery protection. Unfortunately I see they have a max voltage of 25V. It is not an easy matter to find a higher voltage rating, but would be easy to hack the board to reduce the voltage by splitting R41. It will require some documentation and photos and my SL is indisposed at the moment.
Meanwhile, anyone intending to run the SL a
