Hi NM
I hope you don't mind me making a few observations on how this thread has gone so far.
First, I think it is a great idea that you have decided to study and learn how to follow a circuit diagram (schematic). It is one of the fundamental things needed when attempting to repair any type of electronic equipment. Recognition of component types, and how to locate them and a little knowledge of the function they perform, all comes with experience.
May I please suggest you try and stick where possible to the "Trader" service sheets and not American literature.. This will help you to converse with your fellow UK enthusiasts with out confusing them so much. The Trader service sheets have a similar standard of circuit layout and you will more easily be able to see similarities between one manufacturers radio design and another's. The Trader service sheets also normally have a good general description of the circuit and the function of the various components.. The layout is clear and easy to follow with the +ve HT normally shown at the top and the ground or -ve shown at the bottom. I find this so much easier to follow than the American and some European schematics.
Learning the correct terms for things so that you can express yourself clearly is also something which should be strived for and will come from the study of the better schematics, and service sheets.
Second, well done for getting where you are today with the HMV 1124.
Third, Now please dont take offence but as one novice to another I feel I am at least qualified to make the following comments. Please don't take offence at being labelled as a novice, it is not an insult. Even though I did City & Guilds in Electrical installations parts I & II, and passed with distinctions in all papers I have had no formal training whatsoever in electronics, therefore I certainly feel I am a novice. When compared to some like Mark, Terry, Trevor and Jeffrey I consider myself a total amateur.
Since joining the Golborne Vintage Radio Forum I have been following the posts in your threads and have concluded you seem to have been struggling with coping with the layout and access to components and understanding of what is going on. (hence my opening comments)
But the overriding feeling I get has been surprise at how little credit you give to the "professional" advice and comments that well meaning people have gone out of their way to make in the belief that they were helping you. Your attitude of ignoring all help is probably the thing that most frustrates those that try to help you. These and other forum members who have spent a lifetime of learning and experience in the electronics design, repair and service industry are a valuable asset to any forum such as this. I don't like to think that they would be put off from assisting novices such as us when we really do need some help. This forum relies on the generous help volunteered by these knowledgeable members.
This hobby of ours is an interesting one and the threads detailing the experiences of others when tackling the repair of different radios is an interesting subject where we can learn a lot. But they are much easier to follow if they are kept on topic, are more condensed and with the points that others make, tried and followed up with how and if they help..
If there is any thing you don't understand in a schematic just ask and someone should help explain, this is often much better than studying books, as it is interactive learning where you can ask for further explanation, this is not possible with a book.
And last, just a thought, do you know you can reply to a post with out using the "quote" button. If you do wish to "quote" it can help if the irrelevant text is deleted, leaving just the test you wish to quote.
Good luck with the learning.
Mike
P.S. most of my attempts at radio restorations are on the Vrat forum, http://www.forum.radios-tv.co.uk/
