Re: [drakelist] Deoxit helps Jones connectors on a Swan 500cx
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Evan - I wonder about that too, but perhaps someone had been spraying contact cleaner inside the connector at one time. Or perhaps in a saltwater environment in an earlier life. There shouldn't be anything flammable in there. The 300 series had a little fish paper liner inside the backshell, I don't know if the 400 (or 2400) had the same. The 240 appears on pins 1 and 4, which are diagonal, rather than adjacent, but I don't think that changes the path that much. Perhaps some small creature had made a home or nest in there??? Bottom line though is that the 400 series connectors are only rated at 250VAC, and most 220 these days is at least 240, and many very near 250 (125 VAC line), so it might not take much. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B C-Line Service Supplement CDs www.k4oah.com [EMAIL PROTECTED] wrote: [EMAIL PROTECTED] made an utterance to the drakelist gang -- I have my doubts about moisture accumulation in a Jones connector causing it to go up in a blaze of glory. Sounds like some very, very unusual circumstances to say the least. If the supply and RF deck were in the same environment, and there was that much moisture/condensation in the air to cause flashover at 220vac, it stands to reason that there would have been a high voltage flashover or RF arcing in other areas due to smaller spacing and higher voltages. I'm not disputing that a flashover occurred, but I'm apprehensive about the cause. -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --

The pins were so bad that I had to do it a couple of times then clean the residue with RS spray contact cleaner and Q-tips.

Re: [drakelist] Deoxit helps Jones connectors on a Swan 500cx,
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Jim - The Jones connector pins are cadmium plated steel. I'm certainly no chemist, but I wonder if the ammonia, (present in most brass polishes,) is what got the cadmium. It sounds like you may be down to bare steel, which might be a problem in future. Old steel chassis used to be cadmium plated, and would grow the same crud. (Chemical term there.) I think cadmium plating is now among the millions of things that have been around hundreds of years which have now been declared harmful to our health! :-) 73, Garey - K4OAH Glen Allen, VA Jim F. wrote: Jim F.

Re: [drakelist] Deoxit helps Jones connectors on a Swan 500cx,
Dennis Monticelli [EMAIL PROTECTED] made an utterance to the drakelist gang -- You're probably right, Garey. The thin Cd plating could well be gone now. Ammonium nitrate can attack Cd. I am certainly no chemist either and I don't know what was in that brass polish, but according to a material book I have, intentional stripping of Cd from mild steel or Cu involves KCIO3 with Hydrochloric acid, both at about 5%. It is also possible for a cadmium-based corrosive layer to develop slowly, build up thickness and in time become self passivated, leaving a layer of pure Cd underneath. It depends upon the nature of the contaminants in the air and the humidity what type of film forms. To stay on the safe side, I would just keep those pins well coated with an anti-oxident.

Never really thought about it, but the 400 Series connectors are only rated to 250VAC, so I guess it wouldn't take much moisture. The REAL Cinch-Jones connectors are a true bakelite body, while the Molex versions are a thermosetting plastic. Yeah, go figure. I plugged my NCL2000 into the same source and it ran like a champ, so it likely wasn't a problem with the house wiring. I quadruple checked all the wiring, everything was fine, the L4B had been power-up tested on 120v without issues. When I said specatcular, I wasn't kidding. Flames shot out of the connector on the end of the PS-to-RF deck cable. I didn't intend to cast aspersions on Jones connectors, they really are quite good. 73 -Jim -- Ham Radio NU0C TR7/RV7, TR6/RV6, T4XC/R4C, L4B, NCL2000, SB104A, R390A, GT550A/RV550A, HyGain 3750, IBM PS/2 - all vintage, all the time!
