Ben G4BXD proprietor of the wonderful Military Wireless Museum in Kidderminster has recently taken ownership of a rare Eddystone S909A receiver. According to the QRG (Quick Reference Guide) to Post War Sets (downloadable from this site) the S909A was a variant of the S909 but with optional external HT/LT source connectors which is probably why it doesn’t have an ON/OFF switch. Some 225 of these were made from 1959-1963. The EDDYSTONE Type S.909, 1958, marine communication receiver, designed for the Swedish Merchant Marine. Two band (1.6-4.7Mc/s) plus fixed switched crystal controlled channel on maritime distress frequency of 2182kc/s. AC/DC 110-250v. AM and MCW only. Single conversion superhet with switchable crystal gate (IF-465kc/s, bandwidth 10kc/s or 5kc/s at 20dB down). 7valves plus metal rectifier. 1 RF; 2 IF. Built-in speaker. Production run of S909 was 100.

John Gibson contacted us to say his Eddystone 840C worked nicely as purchased except that the magic eye was ineffective even on strong signals. He said that examination of the DM70 data sheet reveals that for the tube to be operational, its plate voltage needs to be held at about 60 volts, half the high tension level. Any higher and the tube is de-sensitised and barely works. The solution is to wire a 10K 1 W across the existing DM70 plate resistor and another 10K 1 W from the plate to ground (0 V). The plate of the DM70 is now clamped at 60 V, and the magic eye works fine.

Ken in New Zealand sent me this picture of an Eddystone part that belonged to his father who also had a much used 680. Ken enquired whether it was part of the 680 or some other set. It looks to me like the shaft insulator brackets that were sold individually as components from the mid 20’s until post war. However, none of the component catalogues in the archive show one with three shaft brackets mounted on a brass base plate. So the question is, what set was this used on or was it a long forgotten Eddystone component?. It is about 180mm long and has the name Eddystone stamped on it. If you can identify it let me know and I will pass on the information to Ken. Chris g0eyo@blueyonder.co.uk .

Mystery solved. I got this reply from Tor Marthinsen in Norway. ”

I’m sorry to say that I’m not so busy with my Eddystone receivers as before, maybe I’m slowing down because of age? However when I saw the ‘mysterious’ Eddystone part you were interested in, I immediately knew where I could have used such a part – in the ‘Amateur Communication Receiver’ as described in the ‘Eddystone Short Wave Manual No.4’. You must look into the second edition, in the ‘List of Parts’ for this receiver you will find the ‘Condenser Cradle No. 1114’. You will also find it in the ‘Components catalogue’ from 1939″.

Bills funeral will be on Monday Dec 5th.

1.30 p.m., St Thomas’s Church, Maesglas, Newport NP20 3AT 

2.30 p.m. at Gwent Crematorium, Croesyceiliog, Cwmbran, NP44 2BZ. 

Family flowers only, donations in lieu to the R.A.F. Association, c/o Tovey Brothers Undertakers, 9-11, Cardiff Rd., Newport NP20 3EH.

I have just heard the sad news from his son, Nick, that Bill Cooke GW0ION, past Chief Engineer and Managing Director of Eddystone Radio Limited has passed away today very peacefully aged 96, at home in Newport, Wales. Eddystone was, of course, a hugely important part of his life and Nick reports that a photo of the factory was on the wall above his bed. Nick will let me know details of the funeral arrangements when known. Bill’s wrote about his life in the “Cooke Report” which can be downloaded from the History section of this website..

RIP old friend

We are grateful to Dave for sending us pictures of his pair of Eddystone pillow loudspeakers made by Eddystone in the 1950’s. Graeme G3GGL (SK) described them in the QRG as follows; “A flat , smooth, bakelite grille, approx. 4” dia. by 1” thick. “When slipped under a pillow, speech and music can be heard clearly by a resting person but will not be audible to other occupants of the room.” circa.1950. Original price £3 14s 3d including matching transformer, flex and plug.  Advertised on the back of the instruction manual for the Model 670. Extremely rare. “.

Dave says that  they were made for Eddystone by ACOS who made crystal gramophone pick-ups & microphones in the 50’s & 60’s. They are high impedance so he  thinks  they are also crystal. The small brown Bakelite box is the transformer of which he only has one.  Primary has 3 taps to match radio’s speaker impedance, the secondary only one winding for pillow speaker. They have PILLOTONE on the front as in the Brochure etc.  All the wiring is rubber insulated. They were sold as Eddystone Accessory Model 1419.

G6XJ Arthur Edwards, (Sales Director at Strattons) in 1929

Matt Twyman GW6KOA who used to be a test engineer at Eddystone in the 1980’s and 90’s (working on 1650 Receivers as I recall) sent me a page from an old Shortwave Magazine of January 1949 which showed Arthur Edwards G6XJ operating his station in 1929. Arthur Edwards was the Sales Director for Strattons for many years from its early days until the early 60’s before it was sold to Marconi.

There has been a long conversation on the UK Vintage Radio and Restoration Forum about Wendy Mott’s experience in restoring a 888. Many people contributed to this conversation and I asked Wendy if she would produce an article for this website on her experiences.
