I'm also interested in this module. I'd like to know if the architecture is similar to the Audio M series line output stages or the Quad QC-24, both of which use the 6111.
The picture basically shows you the schematic. The 6111 is a dual triode so the parts hidden behind the tube are a mirror of whats in front. The very back looks like part of the heater supply. Look at the resistor bands for the values, once you have them its easy to figure out where they go. The capacitor values may not be be visible but again they aren't hard to calculate.
May be this kit is something like shown below, this is for 35Vdc plate voltage. This is just a quick prediction of what this schematic could be. This way it performs as a buffer. 6N16B/6Н16Б could be used.

You mean I must use a voltage divider on the Grid:
220K and 13.3K voltage divider provides 2V bias for the Grid using B+ = 35V.
220K and 10K voltage divider provides 2V bias for the Grid using B+ = 48V.
Vk is still 1V.

I've emailed the seller and rec'd this schematic (see attached).
Anyone built this yet? Might be better with a higher voltage, say 60 or 70 ac volts going in?
