Triplet capacitor question

Can I use a 50v 22p ceramic capacitor instead of an MLCC? Also what value should go in the spots labeled PWR? 4u7 tant caps?

Also can I substitute a 3n3 for the 2n7

Which project are you talking about?
Ceramic capacitor are in fact MLCC. I've never seen or heard of a monolithic (=single layer) ceramic cap before, so I'd assume all are multilayer builds.

This is the VFE triplet build.

Oh, my bad sorry. I thought it was a triplet of questions about capacitors  ::)

Anyways, I think the 0.1 µF caps are meant for the PWR parts as there are 4 pieces with 2.5mm spacing I couldn't find anywhere else.

Not sure about the 2n7 however.

It also calls for 5088 transistors but I only have 5089 I guess I will have to order some 5088s

I think that the PWR caps are intended to be 0.1uf.  Probably at least 25 v.
