'twas just looking through some GE service data - they made a 25MA chassis-equipped set that mimicked the Avanti. Slick looking.
A year later, they made the 25MH chassis -
modular solid state, with a 2-tube VHF tuner.
Also added two transistors to translate the RF AGC voltage - only one model produced with the 25MH, and it looked Mid-Century Modern......in 1973! Guess they had some tuner tubes to unload from Owensboro...
