Thise measurements are as follows:

C3+  = 28.8 VDC

IC1  In=112 mVDC,  G=0, Out=0

3TR5. E=0.130 VDC , C=0.220 unsteady jumping, B= 0

just an observation:

looking at the PS board of BC5500 I see a jumper in series connecting the track coming from rectifier to Input of IC1 instead of a resistor (R11?)

this board looks exactly the same as the one for the BC7000 except no jumper but R11?
