i was just thinking....
if you plan to keep & use that maytag A50 for quite a while, it doesn't hurt to have extra "spare" parts with you, for those "just in case" moments that we never think about & dread, when they do happen.
i know with my hoover 0510 twin tub, when i bought belts, i bought more than one and hoses, i only bought one (washtub to drain pump) cuz that was all i could find. but me & my way of thinking is, may as well buy what you can find right now cuz who knows if you will be able to find it again, later on down the line. especially with vintage or any twin tubs, since they are no longer being made here in the united states. but this is just my way of thinking.
if you decide to go for them spare parts, good luck, i hope you get what you need (& "extras"). ;o)
