I just bought a CR70 on ebay and it looks to come with the universal adapter and the cross reference manual. I also signed up for Sencore -e for more reference info on tubes. How ever I do not think it comes with the operations manual. Does any one know where I can find this. I would like to know how to use this thing before I use it. Trial and error is not what I want to do with old tubes.
