video99.co.uk | Super-rare Grundig SVR4004. A format of only one model. @video99couk | Uploaded 4 months ago | Updated 10 hours ago
Super Video Recording was a doomed video format from Grundig. Based on the VCR (N1500) and VCR-LP (N1700) cassette, this exquisitely rare format used a slightly improved tape formulation to allow for up to 4 hours on a cassette originally designed for 1 hour maximum. Only one model of machine was built, the SVR4004. As well as being very rare, the machines often fail so there are not many left. The available schematics are low resolution, have serious errors, and are written in German. Our machine has broken down. Can we fix it?
