Insufficient video gain in teletone TV-149

[Ralph S]

I'm just about done with a tele-tone TV 149 and have good sound but very low video gain at the picture tube (7JP4) though the DC voltages are correct. I've been through all the usual things: new caps and off-value resistors and crappy micas replaced. I tried pumping direct negative video into video/DC restorer stages and got good pictures, but video off the internal tuner is low and I think it's comes down to one or more open peaking coils on the video and later stages. Have any of you come across this problem with the Teletone line of receivers? I've never had it with any other make, except for the CT-100 RCA color set. Don't forget that the TV-149 is an intercarrier set and the sound quality and level are great AND the video at the plate of the video amp is good. What's going on here?
