When I had the specialist video repair business Tom, I had some big contracts with banks, petrol stations and the railways. When I retired I passed the business to my son who of course carried on with the contracts, and when finally, because of the flood of low cost VCR's the business was no longer viable and closed down, Paul, although having a well paid job as a broadcast technician, carried on with the contracts working from his home workshop and of course kept a good supply of spare parts just for these machines and he's coming to dinner on Sunday, hopefully with the belt. At the end of the contracts the machines were scrapped and replaced with hard drive recorders.
