content: Hello,Does anyone have for sale or know where I can buy an 80pF, 1000v capacitor for my '101zd please? It's C15, the coupling cap from the driver to p.a.I'd be interested in buying a full set of capacitors for the driver and p.a. sections also. (all the electrolytics have been done, I just need the ceramic plate caps).Any help much appreciated, thanks.Chris G0VOE.

content: There are a few Hams on this forum,but not a lot of them.We can probably find you a source for a cap with the right specs,but physical size may differ from what you need.I've never had a FT101zd,so have no idea of the size & shape of caps used in them .A picture would help.Have you tried QRZ.com?---there are many people there who have spent a lot of time on the FT101 series.73, VK6ZGO

content: Chris,I take it you are in the UK.The capacitor in your 101ZD is probably a moulded mica that is brown in color and square?You can replace this with a silver dip mica.Available at :http://www.justradios.com/cart.htmlAnd they ship to UK & Australia.The only issue is they only process min order of 25 dollars.But if that cap is gone other in there are sure to follow due to age of radio. This area of the radio gets a lot of heat and no air flow. I would also replace the screen grid resistors and the HV caps in the power supply.Here is a good start on the repair of this radio:http://www.foxtango.org/ft101zd/FT-101ZD.htm

content: Chris,have a look at this shop in Germany:http://www.rfw-elektronik.de/electronic/glimmerkondensatoren-cde-1000vThey offer a silver-mica 82 pF / 1000 V.73, Ronald

content: If you use the search term "Doorknob Capacitor" you should find plenty of them.Even in the German language, this term is used as "Doorknob Kondensator"

content: Ridiculously late to the game but .....the FT-101ZD uses a 1000pF coupling cap to drive the 6146B power tubes, not 82pF....The really old FT-101 through FT-101F radios did use a smaller coupling cap... 80pF-82pF... to drive the 6JS6C power tubesBruceKB0TJ
