[QUOTE="Ampdog, post: 810750, member: 144"] Also not the right time of 'day' to be fully alert, but it should be trivail to install a gain stage of some x2 - x6 in the ST70 itself, without adding anything externally. (I have done this several times; voltage supply taken off one of the ST70 EL34's cathodes.) If I read correctly, the separate volume control(s) and the lack of gain are two separate matters? Such an extra gain stage can be built right onto the Pat4's pcbs, or into the ST70 if you want the Pat4 out. (Naturally no added audio effect - that is except for a gain increase!) [/QUOTE]
