Whites TDI SL Schematic

[dbanner]

Reverse a scheme from pcb or redraw from original, as Carl says, how could you tell the difference. I don't think they would make a big fuss about these older schematics anyway. They should be gratified that people still take an interest in their legacy products. It is free advertising and promotion of their brand, which they never seem to grasp. They could reissue a limited number of their older models and people would snap them up in no time. Accompanied by something you could hang on the wall, signed by the company big cheese. People like to hang stuff on walls, you know.

China is a reality, deal with it.

I like the TDI series of detectors...i made two TDI's several years ago...i have an original pcb which Eric Foster gave to me several years ago and the circuit diagrams and parts list...Eric was a great guy and its sad he is gone...i still think his design of goldscan 5 which evolved into TDI was one of the best pulse detector designs of all time !!!
