Martin,
?
Comparing your schematic to Steve's I see a few differences:
- The secondary of T2 is directly connected to ground in Steve's and through capacitors in yours.
- 1.2k to ground at the output.
- As noted, 41pF instead of 82pF across loop.
- As noted R4 is 500k instead of 1k.
- R1 at input.
- Extra ferrite beads.
I assume R1 is to bleed of static charge. What is R6 for?
?
Are all of the differences from tracing a different unit or are some things your own changes?
