Hi I founded the Vrat community in 2011, since then it has grown into so much more. We have a Facebook Group and YouTube channel. I hope you enjoy your time with us and check out our other social media presence. Personally I collect and repair early colour television mainly between 1967 - 1977. My other interests include early VCR repair and obsolete media formats such as VCR, VHS,Betamax, V2000, CED and laserDisc. I also collect 1970's audio.
