From the vendor
The post calls it a straight Hermida Zendrive clone using a JRC4558 in place of the AD712, with a three-way diode select switch (MOSFET-and-germanium 'Dumble', 'Zenkudo' and red LED 'Marshall') that also changes a multicolor LED. It quotes PaulC on the odd 10n input cap and 2M2 resistors, which together with the 470n/470K make a small low-end roll-off around 41 Hz.
