Ramsey Electronics PR100 guide

18. Install C1, a .01uF ceramic capacitor (marked 103, .01, or 10n).

19. Install L2, another 2.2uH inductor (green body, red-red-gold stripes).

20. Install R3, a 18 ohm resistor (brown-grey-black).

21. Install C3, a .001uF capacitor (marked 102, or .001).

22. Install R5, a 300 ohm resistor (orange-black-brown).

23. Install FL1, the two section helical filter. Make sure and mount it firmly to the board, and that all leads are

soldered correctly.

At this point we will check all solder joints for possible cold joints or even worse, solder bridges. Make sure everything looks neat and clean before continuing, since the better it looks, the easier it is to find problems.

24. If you have the appropriate F-connectors, install J3, otherwise leave this part out so that you can solder your connecting cable straight to the PC board.

Congratulations! You have completed assembly of your PR100. Before continuing on to install your new preamp, check all of your solder joints thoroughly, as well as part orientation. You definitely don’t want to seal this into a weatherproof container before you verify if it works or not!
