Hey everybody - I'm a total newbie; I've had some experience with circuit boards and op amps, but it's been since college which is over a decade now...yikes.

Anyway - my bassist brought a little practice amp from the 50s called a Mighty Atom into our rehearsal space, and I actually love the way the little guy sounds, and I'd like to replicate the circuit.  Using a multimeter, I've been able to identify all the resistors in the circuit, and the axial caps are obvious (their farad rating and voltages are printed right on them, so that's easy), but I'm having trouble with 6 littler capacitors that aren't so obvious, and I haven't been able to find similar looking ones online anywhere.  They're little, thin, square and terra cotta colored, and I'm wondering what the modern equivalent of them would be.  I also don't really know how to measure them; my multimeter claims to be able to measure capacitance, and I was able to get accurate reads on the axials, but I can't really tell if these little guys are just too...well, little, or what.  There's also a little diode in the circuit with "CPMST101" printed on the side; from above, it's fully circular (not a half-circle like some other diodes).

Any ideas?  I'm attaching a picture of the circuit board here, with a couple of the caps I can't identify circled.  I think once I figure out what these little buggers are, I'll be able to reverse-engineer the circuit, and I'll certainly share the schematic once I do!

Thanks so much for any help!
