Components for repairs and projects

If you need components for your repairs and projects, it is always worth asking around the club as many members carry small stocks of components. These may have been obtained by stripping down old rigs, as a result of buying a “bag” of components (either mixed or of a specific type) at a rally or donated to the member “in case it might come in handy”. In addition, the club is sometimes offered boxes of components.

Our current stock includes:

Need components

The components that we have are available free of charge to club members. Please use our Contact Us form or email components @ g4aym . co . uk

If you have components to offer

Please remember that Amateur Radio has moved with the times and there is very limited demand for valves and other components from the 1950’s and earlier. Please don’t be offended if we can’t accept your generous offer as we have limited storage space.
