Thanks for your response. I don't have a large assortment of higher voltage caps or high wattage resistors on hand. They're on the way, but I wanted to start experimenting with what I had laying around and those were it.

The meter I was using for the measurements is a fluke 117 true rms meter.

If it wasn't already obvious, I will state that this is my first foray into trying to design a circuit. I have built many paint by number kits and they're great. I just thought it would be (it will be) a fun way to learn more about how things work.

Interesting! I'll check how it fits.

Nothing wrong with that. We're happy to help.

Simple cap smoothing after the rectifier will still be very noisey in a single ended amp as you dont get the benefit of hum cancelation in the op transformer like in push pull , adding a choke after the first filter cap , then another cap then resistance of a few hundred ohms followed by another cap would make things much quieter.

My plan was to do something similar to an epiphone valve junior power supply with a few caps to ground and resistors in between them. If I find that it is too noisy I can add a choke later
0.1uF is not enough to smooth the rectified voltage. The 10k resistor draws about 15mA. You need at least 10uF for decent smoothing.
Will I see less DC voltage drop with the appropriately sized cap(s)?

It is absolutely doable.
In the 60's, a typical record player had no choke. Some had just one cap (32-50uF) to smooth the B+.
The VOX AC4 had two 32uF caps with a 470r resistor between them.

Yes.
