These radio, TV, record player, amplifier, amp 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, it may take a little longer! Here in the UK it is 18:31. If more than one schematic is listed for a model I will generally send them all, unless too big to attach! Specialising in British schematics Roberts, Hacker, Bush, Pye etc. also American and German manuals feature strongly, search for what you need. Multi page manuals are Emailed as pdfs. Please Email or phone 0788 4425213 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".
