Retubed the M100 today! The plate voltages measured at 488 VDC and I set my target at 33 MA. I used a probe and got it to 32.5 on the left bank and 35 on the right bank with a new set of SED Winged C EL34's. I have a Mullard reissue 12AX7 in V1 and Sovtek 12AX7LPS's in the other two. The LPS in V3 is a balanced triode. Didn't get to play it today but I will run it up tomorrow morning. Excited to hear how it sounds with new glass in it!
