At one time Sherwood engineering made a power supply upgrade for the r 4 grade receivers. Have them in mine and they have lasted a long time. Look them up on the web. Some interesting stuff for Drakes there. David Assaf, III >From W5XU Desktop

Does anyone have a mask or template of the actual board(s) that I could use to etch my own one-off PCBs to replace the cans in a 2B and an R-4? I understand that we're no doubt talking about two different PCBs for the two receivers. Also, does anyone know of a source of the blue light-filtering material for the R-4 series dials? TNX in advance. 73/arf, Paul, K4MSG
