Reamping box

[mcasey1]

So I plan on building a reamp box to sen a line level output from my mixer to a guitar amp.  I ordered a 10k/600(ohm) transformer from edcor and I was wondering if I could just use it in any readily available schematic that I find for a reamp.  Jensen has one up on their website, but it calls for a 10K/150ohm transformer.  Would it be a noticeable difference in quality (up or down) if I used the 10k/600 transformer instead?  Would I need to change some resistor values to make it work right?

Thanks!
