video99.co.uk | Component level repair the Super-rare Grundig SVR4004. A format of only one model. Part 3. @video99couk | Uploaded 3 months ago | Updated 8 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. Shockingly, we have two of these. Today we go deep component level repair on our second machine, but our first machine comes in handy along the way.
