Did you ever notice the silkscreen for the transistors on the deflection PCB??

hi all.

I thought i'd post my results as i've wasted a few hours on this today building my rig and i'm surprised there isn't any note of this anywhere.

Electrohome G05-802/805 Manual [54-7291-01] Issue 1 AND issue 2 - April and Setember 1980 respectively.

These errors apply to both manuals:

Error 1 - Page 10, deflection PCB schematic, the pinout of the main connector is wrong for pins 9 and 11, they are transposed. Find the 9 in the little circle on the far left of the diagram (GND) and scribble it out, put a 11 above it. On the right hand side of the diagram, find the 11 in the little circle marked [6.3v HTR IN] scribble it out and put a 9 above it

Error 2 - Page 14 - the HV diode D904 is marked with a plus sign toward the anode end of the HV anode lead. This is wrong/confusing, the schematic is correct, the cathode of the big in-line diode (-) should be toward the anode end of the lead, mark accordingly.

enjoy
