Here's a schematic for a nice little 4 bottle 3 X 1 Gates tube mixer in case anyone's interested. Bought this from a forum member recently. Very good sounding amp.
Please note:
The capacitor in parallel with the 6C5 cathode resistor is not an electrolytic. It appeared to be a mica type (small brown square - like a chocolate mint). Could not read any code or value from it. Perhaps a senior member can suggest an appropriate value here.
Also the 1620 cathode bypass cap is an electrolytic. The question mark is there because it was impossible to read the exact value. I ventured a guess of 40uF/25V based on size and the use of this value on the following 6J7.
Current draw at 250V B+ is around 20mA
