I need schematics for a Zenith 7H02Z2 chassis for my R724, and I need the schematic for an RCA 6X7A radio. Didn't find them at Nostilgia Air, they may be to new for Riders. I do not have a sams for the Zenith. I may have one for the RCA, but it is packed away in a box.
Thanks

The Zenith is Sams 178-17, dated 1952.

The RCA is Sams 303-9, dated 1956.

Unfortunately I have neither, but I hope it helps you on your quest :)

The Zenith schematic is in Beitman's volume 12 (1952) page 161.
It looks mostly legible. If you want it, I can make a scan and send it to you or post it.

Thank you Winky Dink! I thought I may have had the sam's, but my collection gets spotty below 400. I did not have either one. I really need to get the first 400 sam's to complete my set. Maybe I can find them on DVD or CD.
