HT by-pas to utilize a stand alone pre-amp


Hello everyone, I was wondering if it would be possible to use the HT By-Pass on my Modwright KWI 200 to use a good tube pre? Maybe even one of Dan's. Will this work, just thinking, thanks.

If I understand your question correctly the short answer would be yes. To clarify you want to use a different preamp but utilize the amplifier section of your KWI200? 
Yes that is exactly what I want to do, just was not sure if it was possible. Also not sure what tube pre-amp would be a good choice to try, thanks, Allen.
