I am pretty sure that used a 50k stereo Nobel pot. Take a look at it and make sure. You can also measure it with a DMM.

KHOZMO-74447 should be the right one.
I am rather clueless here... DMM? I dont have one.
Can anyone confirm that the KHOZMO-74447 will work?

Thank you for pointing me in the right direction
Sorry the DMM is a digital multi-meter. If you don't have one and don't know how to check resistance,skip that suggestion.

The schematic for your preamp which I found on the web shows a standard stereo pot. "potentiometer" 6 pins. One ground, one input and one output per channel.

Take a look at it. It should have a sticker on it somewhere that says 50k or 100k. Those are the most common values anyway. Or if your going to have the work done for you have them check it for you. If it is indeed 50k and you have the physical room for that stepped attenuator it will work and be a nice improvement.
I do want to do the all the mods I'm planning myself...
Upgrade the attenuator, caps, resistors, tube sockets and power supply
If you're 'rather clueless' and do not own a DMM, I am not sure you should be performing these mods yourself...you could do your amp, or worse, yourself, quite a bit of damage.
Just sayin'...
