Having read schufti's post, I decided to try an ESP-01 module. The module I received is black and uses a "BergMicro 25Q80A" SPI flash chip. It also came with a power LED, which I removed.
With the same program and almost the same circuit as my previous tests, the voltage across a 1 ohm resistor was too small for my cheap 2000-count multimeter to measure. I substituted a 10k resistor which I shorted out until the chip was in deep sleep - then I measured 163 mV across it, implying 16.3 µA
I'd still prefer to use the ESP-12F module, as it exposes more IOs, including the all-important GPIO 16. So I guess I'll work through the differences between the modules and circuits until I know what it is. Based on what bbx10node said, the AMS117 will be the first thing to go!
