This is my favourite television. A 1970's PYE solid state portable B&W television, model 12G13. It can run off either mains (~240V, 50Hz) or a 12VDC supply. It has a VHF turret tuner and UHF tuner. I bought it from an antique shop for $20, negotiated down from $30 due to the digital switchover. It's a great set, and I watch it a lot now - it works because I run my own low power analogue UHF transmission.
