If the unit still has its original back, it should have a model number printed on it. It will likely be four numbers, preceded by an A or a B - for example, A.1234 or B.2345.

If you can share this information with us, we might be able to track down something if it is available.

Unfortunately, service (and other) information for British-made Philco Tropic receivers is not always available anywhere, not even on the UK Vintage Radio Repair and Restoration forum.
