Hi, new to the group, ive been lurking for a while! A work colleague gave me an Eddystone EB-35 mk1 as a restoration project. MW seems to work, but most of the...
A good point re: the transformer and the posibility of other mods. I'll tread carefully. Thanks for the tip Gerry. ... set ... check it ... Eddystone ... (I ...
Hello Martin and welcome to the Forum! I would start by contacting Ian Nutt to see if he has a replacement L6 in stock (also, he has just posted some lists of...
Martin, The coil you need is I believe part number D3518. I have these available in stock if you would like to email me directly. 73's, Ian M0ECQ To:...
Hi Gerry, thanks for your reply, I have made a start, firstly giving the potentiometers and the switches a good soaking with servisol, then taking voltage ...
Sounds good Martin - I forgot to mention the 'sharp crack on the head with the butt of a screwdriver' trick! - I tried that on the OC171's in my EC10 but it...
Hi I recently picked up a new 4-gang tuning condenser similar to that used in the 940 receiver in a box of junk parts and wondered if anyone can comment on its...
Hello Simon, The front-end in the 940 is quite interesting - it has a 'cascode' double triode stage followed by a pentode stage. The cascode design began to...
Hello Group! Anyone had a problem with the BFO on an EC10 MKII? The radio has never missed a beat (so to speak) but I turned it on yesterday to listen on 80...
Hello Gary, I do not own a MkII EC10 but have some experience with a MkI (same BFO circuit). I would check: - ensure that the power is getting to the...
Hi Gerry Many thanks for the info. I shall be investigating the problem when I get a spare Saturday. The EC10 is mainly used out in the garden, which this year...
Hello Venk, What information do you need? Ian Nutt has a stock of some Eddystone- specific parts (lists can be downloaded from the EUG site) and occasional...
Greetings, I'm the new caretaker of an 830 that needs a new knob for the band switch. Anyone have one that they would part with? Please let me know price...
John, Welcome to the forum. I would suggest you contact Ian Nutt (contact details on the EUG site) for the replacement knob. I purchased same for my 940 from...
Well I think the radio has a poltergeist! Checked voltages on TR6 okay. Turn radio on its front BFO works (re-check voltages TR6 - still ok). Turn radio back...
Gary, Did you check the TR6 voltages when the stage went off? - sounds like a mechanical fault (eg. dry joint, loose wire, metal sliver in the BFO tuning gang,...
Hello, John. I'm a member from the USA, and I've found radios and members to be mighty scarce on this side of the pond! I may have a knob for you, but it...
Hi Gerry Well I dunno how the BFO worked on its front but have now solved the problem, R35 had gone up in value to 54k, put a new 47k resistor in and bingo. So...
Good job Gary. Carbon composition resistors do tend to go high in value with age (and can become quite good noise generators per the ones in the 1st AF stage...
Hi, Im in the process of restoring this set. I have today replaced all the electrolytics, but the audio output is still extremely distorted. This is on both AM...
Martin, I would suggest trying to isolate where the distortion is originating from: RF/if/detector or audio. Try coupling a known good audio amp/speaker to...
Gerry Thanks for the advice. I think the RF/detector stages can be ruled out. The distortion is just as bad on both AM and FM, although of course now ive bust...
Martin, You will not hear much with the speaker connected to the volume control pot - not enough to check for distortion I suspect, and the impedance is wrong ...
Im afraid not, at least nothing easily to hand. The bench isnt set up for repair work at the moment. Although i have all the parts for amps etc in front of me,...
Martin, Yes, that is the curse of the direct-coupled amp - one thing affects another. I recall changing whole sets of transistors in amps back in the 1970's...
It is proving to be a bit of a swine! The two bias resistors proved fine out of circuit. I didnt think to check the non-electrolytics, i will do that later. Im...
