Title: 500 volt ceramic, NPO and mica capacitors for SX100?? Post by: wa2dtw on May 14, 2007, 01:17:36 PM It appears that I will have to replace some capacitors to get the SX100 to function properly on 75 meters. They are:
C53 - 10 mmf 10% NPO 500 volt ceramic C54 - 220 mmf 5% N330 500 v ceramic C55 - 240 mmf 5% 500v mica (the only one in the Allied catalogue) C57 - 11 mmf +/- 0.25 mmf N1500 500 v ceramic C68 - 1000 mmf 5% N2200 500v ceramic C70 - 100 mmf 10% 500v C71 1 mmf 10% N750 55v ceramic Does anyone know how I can obtain these? The Allied catalogue lists only one, appropriate for C55. AES and Newark electronics do not list any of these.

and http://www.justradios.com/capacitors.html#product I'd go with silver mica in place of the ceramic caps. Also, I wouldn't replace 'em unless they really needed replacing. "Justradios.com" = fast, excellent service, BTW. Title: Re: 500 volt ceramic, NPO and mica capacitors for SX100?? Post by: WA2AAE on May 15, 2007, 06:58:08 AM I purchased some temperaure compensating caps when restoring my Hammarlund SP210 from Surplus Sales of Nebraska. If I remember correctly they were not very expensive. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
