These radio, TV, record player and tape or cassette recorder schematics,circuit diagrams and service manuals are mostly high quality, very readable scans and will usually be Emailed within an hour or two, if I need to scan an item, or it's the middle of the night here (it is 01:59 in the UK) it may take a little longer! Specialising in British schematics Roberts, Hacker, Bush etc. also American and German manuals feature strongly, search for what you need. Multi page manuals are Emailed as pdfs. Please Email if you have any queries, or you require any vintage parts for your repair I'll let you know what I have! Thanks for looking, Mike.

Search for your Schematic




Fill in the "Make" and "Model" boxes, if you are unsure of the model, leave it blank and I will list ALL models for that manufacturer, similarly if you only have the model number leave "Make" blank and I will list similar model names from ALL manufacturers.

The search logic is slightly "fuzzy" in that it's case insensitive and ignores punctuation so, model TR-510 is the same as tr510, and G.E.C is the same as "gec".
