Listmates, The WRL Globe King 500's use a couple of ceramic (?) RC networks made, I believe, by Centralab. The two used are marked "PC91" and "PC81" ... does anyone have specifications for these? R and C values? Thanks in advance and Happy Holidays to everyone. 73, Bob WØYVA Personal site: http://www.isquare.com/personal_pages/ras-hardware.htm
