Input jack(s)

[sliberty]

I know that the EXpress only had a single input jack, but since my build is based upon a salvaged chassis (with 8 inputs!), out of necessity, I will have 2 inputs. If this amp used 68k resistors like a Fender, I wouldn't have to ask this question as that arrangement is well documented in hundreds of schematics. But since it doesn't, I must ask - how should I wire the two jacks? Ideally, one would bring a hotter signal to the first stage than the other, but in the end, its not that important.

Thanks,

What you could do is wire the inputs to take advantage of the unused triode. You can have a look at the Trainflex schematic showing two different wirings.

One has inputs to use single/parallel first stage; the other let you select between a first stage with Express or Komet cathode bypass values.

I did the single/parallel in my built and just ignored the 68k.

I would put a 68K resistor between them. So one jack goes straight to the grid, the other to the same grid thru a 68K resistor. I guess I'd also put my 1M resistor right there from the "low" side jack (behind the 68K) to the ground lug on the same jack, so te R to ground from the "hi" jack is 1M + 68K and the other "low" jack is 1M to ground.
