Hello, I'm currently working on restoring a 5S119 and have come across a notation in the schematic that indicates a phono jack input and phono switch. Additionally, there's an alternate drawing of the second detector tube labeled, "Circuit changes for phonograph."

My radio does not have a phono jack/switch and after looking at other photos of this model online, I haven't come across one that does. The circuit changes are very simple though, so it certainly helps if I wanted to add this input. Was it intended that others would do the same themselves using this schematic as a guide or was this actually a factory-supplied option from Zenith?

Any insight appreciated.

Hello Christopher,

the schematic is for 7 different models.
Look for the model Zenith 5S127A Ch= 5516, there you will find the phono input.

Best regards WB

Thank you, Wolfgang. I did see the other models noted on the schematic, but it didn't dawn on me that only some of those models would actually have the phono input. Thanks for pointing that out and I'll now look up the 5S127A as I'm curious to see how they implemented the feature in that model.

Take care and thanks for the clarification.
