Tele-tone &" Porhole Television Variations

[Konrad Schiecke]

I recently purchased a suitcase type tele-tone 7" porthole TV. It had no model # label and the back was missing . My sams set #95 shows a Model TV208TR and TV220. My set never had a front cover and the tube line up is different. The 6SL7 is interchanged with the 12SN7on the layout. Also my set uses a 6x5 as a tripler like some of there horizontal 7" sets. I purchased a Sams set #90 which shows no front cover and covers a model TV208. Unfortunately this model uses a ballast tube and a 6AL5 horiz. sync disc but no 6x5.
My question is what model do i have and is there a schematic to cover it?
Thank you, konrad
