GE made Bradford Porta Colors using all chassis except the HE and 10QA chassis, looking through the Sams.

It also had an intermittent mixer transistor in the VHF tuner which would work for days, then stop. Just touching a test probe to one of the tuner test points would make it spring to life, but it would eventually fail again.

If it was the one with a MOSFET mixer, blame the NEC (Japanese) mixer transistors made for GE. I forget the EP15X number, but we saw a couple of those. Bitch to get at in the tuner! The blue sheet warned about the time, suggesting a tuner swap if the time went beyond an hours' time. It also affected the bigger screen JA sets and one MA chassis/model.
