SD2000 maintenance

Hi everyone.

I have just purchased a SD2000 and I want to do some maintenance on it. As anyone who has opened their detector will know, all the components are covered in paint which makes them very difficult to identify. I have only opened my case but not removed the circuit boards as yet.

I would like to know if anyone out there has done their own maintenance and if so, can they let me know what value the capacitors are on the circuit. I want to start by replacing those components. There are 5 that I can see and I would like to know if anyone knows what value they are and which way the polarity goes on the board. If I scrape them to get the paint off, or use paint stripper then I could possibly remove the identification off them.

If you could also tell me what other components should be replaced on a regular basis I would greatly appreciate it, especially where these components are located on the circuit board.


Woody from Link Technologies also indicated the following below.

“On the 2000 change the input diode on the coil drive to a new lower loss ultrafast with soft recovery. Change the 2 irf720 fets for something with lower on resistance and higher voltage rating. Change the p and n rx fets to low c and r types. n is 200 v rated p can be 20 v rated. put in a 3.2 Mhz xtal and you have a very good detector.”

I would also like to know if anyone has done this themselves and which components and values they used for these replacement parts.

Hoping to hear from someone soon.
