Thanks, Ron. I did find some info on your site, the 89 schematic with notes about the 36/77 osc tube I had not seen before. This explained the component value changes. It's intresting to know the changes that took place on sets like this, an insight on problems they had back then. I would appreciate that 'Changes in Models' info when you can get to it. Ken
