I saw the page Yashica_YC-64#Symptom_or_Problem_Encountered had a humming transformer marked as a symptom. This is typically caused by a transformers steel plates coming loose. We should have a specialty page that describes these symptoms in more detail and explains how a transformer can be resolidified to keep the plates stable and silent, I believe lacquer is a technique for that.
A page that details the different kinds of mounting glue used for components and capacitors on PCBs. With the intention to educate that the glue is not a leaking capacitor and possibly to cover types of glues that can become corrosive over time.
A short and simple page that talks about rifa capacitors that blow up. Just information on identification, replacements(or just removal). This will eventually be a page linked to int the infoboxes for devices with Rifa caps so people can quickly find out information on them before opening the device or powering it on
Dallas clock battery replacements. A guide on cut modding different dallas clock chips to connect external batteries or outright replacement parts. This would be linked in the infobox of devices with dallas chips.
