I know the 25V 100uF cap is on order. I ordered a 35V 100 uF cap as a replacement. It has the same specs as the 25V one, just a bit taller, and $.01 more. Depending on the part, mouser may have a substitute part, just make sure the specifications are the same.
They are also out of the power connector for the wireless tx, and the clock. The old one shows that it has been replaced. But still shows new part on order.
The red led should be a T1 size, but mousers replacement is T1.5, a little digging you should find a red led that is water clear that is the right size, voltage, and current.
Ordering parts can be a bit of a pain, but that's DIY.
Have fun
