Steve I don't have that schematic but I recall thos Zeniths used ICX3401 part # 221-466 (NTE 7096) and ICX3402 part # 162-18 (NTE 3041). I have them both and you can have them because I don't need them. If you want them send me an address.

Circa 1986 Set. Need Values of R3424 and R3425. If anyone Has a Diagram or a Scan Let me know. I did not check our Archives yet because I think the Set is too old. Will Check Leter just to be sure. Set Not Powering Up - Found Some Tips on Some BAd Caps, but if anyone Has worked on this Chassis, I'd Appreciate a Chat With them.
