Eddystone EC10 Power Supply 4 Pin Connector
Hi all.
I am almost finished on a mini restoration of an Eddystone EC10 receiver. The power supply plug is functional, but one wing is broken. The connector is marked McMurdo. Does anyone know what these are called? Does anyone have an old McMurdo catalogue with these listed? Does anyone know where I can buy or get a plug please? At work, in a previous life, we literally used thousands of the ten pin versions of these connectors on modules in audio and control systems. I think we called them McMurdo PP10 and PS10. Thanks mike |

Re: Eddystone EC10 Power Supply 4 Pin Connector
As far as I know, these are now unobtanium. You could try the eddy yahoo group
https://uk.groups.yahoo.com/neo/grou...io_users/info; Ian Nutt has many spares. If you find a source, let me know... WARNING When used on the AC mains power supply, these connectors are unsafe. There's lots of info the EC10 and all Eddystones on on http://eddystoneusergroup.org.uk/ cheers JohnB |

Re: Eddystone EC10 Power Supply 4 Pin Connector
Hi Mike,
I'm just up the road from you in M'Dore. I looked through my parts and sadly I couldn't find one of those plugs, that short one seems quite unique to the EC-10 and I haven't seen it elsewhere. I really like the EC-10 and have a few of them, on one it had an L/O buffer added to drive an external frequency counter with the IF offset applied. All of my EC-10 units have had the RF transistors replaced due to the tin whisker problem. I used AF178's which I bolted in using the method shown here: https://www.vintage-radio.net/forum/...d.php?t=139849 |

Re: Eddystone EC10 Power Supply 4 Pin Connector
Hi John
thanks for that. Mine is an early version, battery only. Wonder who in Eddystone dreamt up the silly and dangerous mains operation practicalities. I have asked Ian Nutt from the Eddystone User Group for info, inter alia. G'day Argus Thanks. I will post a short note about my EC10 on this and the EUG forum, soon, when finished. Three EC10s? mike Last edited by Radio1950; 19th Feb 2018 at 10:20 pm. Reason: Not enough coffee |

Re: Eddystone EC10 Power Supply 4 Pin Connector
Hi Mike.. To be honest.. this is surely an excuse to find an alternative connector. Any two pin will be more suitable than the stupidly dangerous mains connection. How did it pass BS415... the safety standard of the time.

Re: Eddystone EC10 Power Supply 4 Pin Connector
Dismounted "High horse"...Yes Tanuki... As the case is earthed, and the live parts un accessible..it was to standard. But in our case, it is a dangerous thing to have "floating about".... apologies.

Re: Eddystone EC10 Power Supply 4 Pin Connector
Mike, I think that I may have one of those in my spares. If Ian Nutt can't help, drop me a PM.

Re: Eddystone EC10 Power Supply 4 Pin Connector
Mike, maybe a bit late but there is just the one on ebay, it jogged my memory.
Search for 162952709132 No connection to myself! I saw it whilst was doing a search for a guide price of an 880/2 rx and then searched the forum to find it was you looking. Rob

Re: Eddystone EC10 Power Supply 4 Pin Connector
Hi Rob,
Thanks for the lead. I have only just seen your post, as I am travelling in Zambia. Searched in The Big Auction, but no response. I initially that your post date might be suspicious! I have twice tried to email "the man", and will try again when I get home. Regards |

I eventually found a connector on eBay. Used but OK. Might give hope to other searchers. Thanks also to Hermit for the offer. |
