Hi I wonder if anybody has a mains lead for an eddystone 940 or just the plug
that I could purchase.I am located in north wales.I bought the radio at a rally
with a promise the plug woulbe sent but nothing has come.Or if somebody knows
where I can purchase one. thanks in advance John.

I just got back from the mayo (ireland) rally,I managed to pick up a 940 in
great condition!!.It cost me 150 euro and I am very pleased!.I just wanted to
tell someone!. Best wishes from a very wet and windy west of ireland, terry
lynch.

I'm making good progress on my 830-7 project.  I've replaced the damaged dial
scales. Thanks Ian. Now I'm having trouble reassembling the thing.  Can someone
verify the proper thickness of the dial glass.  My set has a piece of 1/4"
Plexiglass (Perspex?) that seems to me to be overly thick causing clearance
problems for the dial cursor.

Thanks,
Al

I note that the Marconi HR100 Data Sheet (aka S750/2 according to the QRG) has
recently been posted to the EUG site confirming that this model has the standard
110/240v 40 - 60Hz mains tansformer.

Hello. Im new to the group. Earl VE3AB. I joined because I was given a box of
Eddystone Receiver parts by a ham op here in Ontario who was cleaning out his
basement. I did try some searching on the web and have not been able to identify
this radio. It does not seem to have a model number on its parts BUT I have
created a PHOTO ALBUM under my callsign VE3AB. To me, it looks like a mobile or
portable radio. The digital readout module is in the pics. I think I have a VFO
module sans the vfo chip as well. I may well be selling these parts off because
I have other recievers and radios which I have to work on and have not enough
time to reconstruct this one. Any ideas? Im sure someone in this group will
probably know. Cheers es 73 Earl VE3AB

Why NOT use coax ?

The primary of the first RF transformer in the 680 can be operated balanced or
unbalanced as preferred, by grounding (or not)the "AE" terminal. The coax screen
also goes to this one. The inner conductor goes to "A". It may actually be
better to leave AE ungrounded, as this will remove a potential hum loop - try it
and see.

The 400 ohms impedance is no problem - a close match isn't mandatory. To quote
from the handbook "The input impedance at the aerial terminals is nominally 400
ohms, but good results are obtainable with aerials of widely varying impedance".
My 680X is actually a special made for the British Post Office, and it has a 75
ohm coax connector instead of the A and AE terminals. As far as I can see, it
still uses the regular first stage input transformers - so no problems in
substituting an unbalanced coax input.

Hello,

  I am looking for one or more No. 707 miniature holders for the 706 Series
tuning coils. For reference, please go to the photo album, 'VE3AWA' for photo.

Hi Gerry

I fully agree with your views.
In my case it was kill or cure !
Photos / scans can be seen in the 'photos' section of the forum.

Hi

Regarding the different shades of dial colours, I have a 680X where the
main dial is a pale cream colour as is the "Model 680X" ident. The fine
tuning dial and meter scale appear white. At the very least this assumes
different paints were used though perhaps they started life a similar
colour but with different responses to fading.

Many thanks for the replies, Simon and Mike - apologies for getting your
callsign wrong, Poo !

With Ernie apparently out of the picture I Googled stove enamellers, of which
there seem to be quite a few. One in Reading sounds promising, even has a
picture of an E Type rear subframe, Mike !

www.unimetenamellers.co.uk

They also do hammer & wrinkle finish, with a wide variety of colours. I'll try
and get a ball-park price and come back with the info.

Regards to all,

Eddystone Cabinet Painting

Unfortunately Ernie of Stoverite retired this month and last time I spoke to him he was unsure if the company would continue or not. I see him every month at the local classic Jaguar club. Ernie re-painted some of my mkII type cabinets for old times sake but told me it was not an economic job.

Hi Bob

I haven't cleaned the dial on my 730, as it was in good order.
However my Mimco version of the 670A (R2232A) was in a really filthy state,
including the logging dial.

These I cleaned with a resin car polish - Autoglym - and they came up very
nicely. This stuff is slightly abrasive & too much pressure will damage the
lettering.

I've used this proceedure on two logging dials & one tuning dial without cusing
any loss of letting.

HI   I have today collected the above  .  whilst i have many other rx and
transeivers  his is my first  Eddystone .
It is in working condition with signals on all ham bands.
I cosmetic point i would like clarification on   .  The large Scale is a lot
creamier coloured than therotatting frequency dial which is White  .  I hesitate
to start cleaning  main scale which is not dirty but faded but it looks out off
place with white rotating scale   is this common  any views .

Technicaly i will do a voltage and frequency check  . Are there any known
problem ares which i should be on the look out for ? update   etc thanks bob

There is also one on the Eddystone Bugkey. Just google Youtube Eddystone bug key
and you should find it.

Thanks to Gerry for finding these gems.
