38-116 Input Transformer Info
#1

Hello Everyone!

It's been a couple of years since I've posted. I decided to re-visit my 38-116 since I've got it playing. I knew it did not have the correct output transformer but never paid much attention. I finally checked the  specs on the Hammond hx 126 series and it is only 4 watts.  I've read some posts here and see many go with the hx-125e or the hx1650f.  I chose the Edcor gxpp15-4-8k.   Looking at the specs of the original transformer the primary resistance is 7600 ohms. The Edcor is 8K. My question is will the extra 400 ohms cause any major changes in tone or clarity?  With the current transformer the radio sounds just ok, not much fidelity, volume up almost 1/2 way....just doesn't bark so anything would be an improvement but I'd like it to rattle the windows!!        

Thanks!!
