Project Radio Difficulty Ratings
This is to give you a rough idea how much work is involved in the restoration project radios that we sell, and to help you decide if it's for you.
The one thing you will find invaluable when fault finding on any vintage radio chassis is a multimeter with a capacitance measurement.
Wax paper capacitors nearly always go faulty with age, this will save you a lot of time.
Well nothings really easy unless you know how but if you can read a circuit diagram, understand the basic principles of how they work, and use a soldering iron you should be in with a good chance. When we give this rating to a project, it means that
The circuit is fairly straightforward and standard
It uses common valves or transistors that are still relatively easily obtainable.
The service information is available
You need only the minimum of test equipment (usually just a multimeter)
The set is complete and no vital parts are missing
There should be no difficult alignment procedures.
There should be a minimum of cosmetic work required.
These projects are more suitable for persons with experience of restoring vintage radio sets, or for people who fancy something a bit more challenging.
The circuit is more advanced, such as set's with VHF FM stages.
Special techniques may be required for alignment
May need more advanced test equipment - such as signal generators, signal tracers and so on.
The case may need more cosmetic work, such as French Polishing, or waxing.
Service information is hard to come by, you might well have to do without it.
More bizarre valves to deal with - this makes it more interesting sometimes.
Complex mechanical arrangements, such as tuning drives
Please remember that this is just a guide to help you, we base the assessments on past experience, more or less work may be required to complete your project.
