Anyone have any feedback on this model? is it good with testing old color roundie sets? is it able to test most or all tubes for these type of sets?

It would be fine to test all the TV tubes excluding CRT's of course that roundies would use. I use a 605.

Ok, Just making sure.. I just inquired one off Ebay..

I shall inquire as to whether or or not you acquired it after questioning Ebay about it?

I just purchased one off Ebay, if that's what the question is..
