Thank you James. I did in fact replace all 3 ax7 with 5751 but the difference as you mentioned was slight. On the other hand I changed the FB resistor which was 7.5K to 6.8K which yielded about a 10 degree difference in preamp volume control. Actually, I have just since sold the amp but I will pass on the information to the new owner. Thanks a bunch, Dak
