Top class product, I printed it out on A3 paper and it is clear and very easy to follow.
Cheaper than buying a new radio!

is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components

Hello.
This paper enable me, to bring this lovley Scope into Function.
Without this Page, i have no cance to make this finish.

5-11. VPP sensor circuit
Protection circuit
To prevent the circuit breakage, the protection circuit watches the voltage level of VCC, VDD and VPP. When the each voltage level is more than following condition, this circuit cuts the voltage. VCC,VDD: In case these voltages are become over voltage, this circuit outputs �SCR� signal(High signal) and burn out the fuse. In case the VPP voltage is more than 15 V or less than 13.9 V, the �VPP.S� level is inverted and CPU cut the �VPP.ON� signal.
VPP:
Detection voltage level (Unit: V) VCC >= +6.5 V VDD >= +6.5 V +13.9 V =< VPP <=15.0 V
5-12.Power supply circuit for display
VC VP GND
This circuit is making the power for display tube. Voltage level: -VN VF1 - VF2 Est. -31.2 V Est. AC4.85 V
