Work is going ahead slowly.
horizontal oscillator seems to be fine, bit a bit low which makes sense sice the FB is not in yet for feedback for it yet. about 28v PtP. on the grids of the HOT. The vertical oscillator is NOT running, and from what I see it can't If I understand things correctly, the OSC gets power ( T109, V16B) via boost through r178 from pin one of the FBT, also goes to G2 of the CRT, filtered by C202B. http://suzaku.live-evil.org/no-vert-osc.jpg So, if I understand this circuit correctly. long of the short of it is, until the FBT energies and that boost come up, the vertical oscillator won't start.
