Dude,
Those are my "hen scratches". ;> ) I "robbed" Sherwood and added some tweaks for a fellow with different O/P "iron" and no o'scope. Compare with the original and notice the brute force method of phase compensation.
Since you have Sherwood O/P "iron", you can copy the original "verbatim", but use a 6BL8.
A nice thing about a pentode I/P stage is the absence of worry regarding C Miller related HF rolloff. Don't try that 1 Mohm grid to ground value with a 12AX7 section.
