1977 Zenith 9" rolling problem

[Raddion]

Hello everyone, it's been awhile since I've posted. I have a cute little Zenith - Model K092X / chassis #9JB1X - that I'd like to tinker with. The vertical hold is kaput and I'm interested in advancing my troubleshooting knowledge anyway. I see that the schematic for my TV is available for a fair charge on the SAMS site, but I'm reaaally hesitant to use my Debit/Visa on the internet like that and I no longer use any regular "credit" cards that would offer more protection. I can't believe there isn't a PayPal option on there! I did try the search function here on VK to look for prior posts on this topic, but I'm probably not wording things right or something.

Does anyone have any idea if the SAMS site is ok for using my debit card info on, or possibly have in their possession a schematic for this little TV set? I really appreciate any help, tips or ideas, thank you very much for reading!
