DYNACO Pre-Amp PAT-4...with an added Volume knob

I just purchased this pre-amp
It sounds good but someone added a volume knob in substitute of 
the input headphone jack.
I looked inside of unit , there is a volume pot installed instead of input jack.
Has anyone ever seen this modification before?...if so , what is it used for?
Thank you

WOW that is a of of information. One heck of an upgrade too.

I have a PAT II all valve unit.. I bought the kits over 2 years ago.
(my interest in this thread)

Distortion reduced from .02 to .002 10X reduction.. lot of work!

Here is an UPDATE on Dynaco PAT-4 pre amp......
As you know from my previous post, I was asking about a volume control knob that someone installed in my pre-amp's input jack.
I now have found out  the knob was used to regulate the volume on Output 1 .
I hooked the unit to Output 1 . 
( there is an Output 1 and an Output 2 )
Output 1 regulates the volume.
Does anyone  know why this second volume control was added onto Input jack?
The music does sound better on Output 1.
Should I leave it hooked up that way ?
thank you
