Anyone know what the yellow component marked 105M is?

I'm pretty sure it's a 1UF cap. Not sure what the m stands for though.

That's what I thought. But I've never seen a cap like that before.

The M is its manufacturing tolerance. 20%.

Awesome! Thank you both.
Is it some kind of mlcc?

its an axial tantalum cap (the shaved off side denotes polarity)

Interesting. Thanks.

If anyone is interested it's the first stage cathode bypass cap in the clean channel of a Mesa DC 10

Yep, tantalum cap.

Be careful, with these, never to reverse the polarity. Tantalum caps can be ruined by just one application of reversed voltage. Cap codes are the same as ceramic disk ones.
