Hi, This set doesn't have a power lead. I went to my father in laws yesterday and we searched high and low and couldn't find it. Mind you, I did find an old...
Greetings! The connector for the 670 (for that is what it is) has not been available for years. The best way to deal with it is to carefully remove the...
My Eddystone collection stared out with a 730/4, and I also have a 750. It seems reasonable to assume that the 750 dual conversion technology would have been...
Hello Chris, The 730/4 cost four times the price of the 750, so that's no reason! The 750 was adopted by Marconi as a land station Rx called HR100. A bit of a...
Greetings! Yes, your 880 is the original pre-production model of MAY 1959. It was not sold in the trade but disposed of to one of the Stratton workers,...
Hello, I've just bought a 770R for restoration which seems to be in reasonable condition except for two fairly big problems. The flywheel friction drive to the...
Hello Keith. The drive cord lacing is described in the handbook. The friction drive is considered to be a factory servicing job and isn't described. The only...
Thanks for that information. Lokking at the drive cable layout, it seems that I'm also lacking the two pulley gears so I'll probably need a scrapper Cheers ...
Hi Keith, Check out my S770R restoration article on the EUG site as well as some of the other restoration articles, which include several photos of Eddystone ...
The EUG website is in the process of uploading the service manual for the IMR54 receiver. However the circuit we are working from is rather poor and difficult...
hello Chris, it's possible that Ted may have one. He's holidaying in the I.o.M. (Brrrr) at the moment. I'll enquire when he returns. Graeme. ... From: g0eyo...
Hello Al / G8DLH, Assuming that the IF is properly aligned, the most likely problem will lie with one of the OC71 transistors. These have now become very...
Al, I think Graeme means the OC171 transistors in the RF and IF stages (the OC71 is in the AF stage). The OC171's have four leads, one of which is an earth ...

Hi All, I found one Eddystone 5500 in a surplus shop. I made a search in Google for the technical manual but I found nothing. Since this transceiver Xtal...
Hakan I think you might mean Orion 5000, 6 channel 100W transceiver. You can view data sheet in our website www.eddystoneusergroup.org.uk in Data sheet...
Hello Chris, been looking at this one; the 5500 is the military version (shown in QRG). I think it was trialled by NATO but not adopted. There is a big NATO...
To: Alan Ainslie. Thanks for that. From the EUG Web Site I was indeed able to get a copy of the Service Manual for the EC10 - including the supplement for the...
If you send me your email address then I will post you a cct. Maybe I better scan a copy of the cct for the web site. Alan. ... Service ... EUG ... ...
Graeme It could be the 5500 but we sold so few of those and only to Ghana military. We certainly never had it trialled by NATO it was styled just to give a...
Had not realised that the circuit of the EC10 Mk2 was missing the left hand bit. We now have better copy of the EC10Mk2 manual available to put on the web site...
Hi all! EC10 Mk. II. Tuning cord broke whilst other repairs were being undertaken! The manual (from the EUG Web Site) describes the re- stringing procedure for...
Hello Al, I've repaired drive cords on EC10 Mks I & II (not at the same time!) and haven't been aware of a difference. As I no longer have either I'm afraid I...
Hi Graeme - Yes . . . Drive cord trouble . . "Apply the ol' grey cells". There speaks the Voice of Experience. So I did - and fixed it! When I studied the...
I KNOW this sounds awfully bland, but was not the 730/4 particularly designed to a rather exacting spec. issued by the M.O.D.? If that spec. specifically...
Hello Al/Chris, The 730 series was an Eddystone private venture which was adopted by the MoD. It had to be beefed up a little from a mechanical point of view...
