【转】发几个VTTC的电路图
C2 - Filter cap, 1360pF 10kV ceramic.
C3 - Tank cap, 1880pF 20kV ceramic.
C4 - Grid cap, 1360pF 10kV ceramic.
C5 / C6 - Filament filters, 0.1uF 1000v polypropylene.
L1 - Primary coil, 25 turns insulated wire on a 150mm former.
L2 - Feedback coil, 20 turns insulated wire on a 150mm former,
mounted 1cm below the primary coil, moveable for tuning.
L3 - Secondary coil, 1000 turns 0.315mm wire on a 68mm former.
L4 - Anode choke inductor, 10 turns close wound on R1.
R1 - Anode choke resistor, 100R 10W wirewound.
R2 - Grid leakage resistor, 5-10k 10W wirewound.
R3 - Screen bias resistor, 21k 40W wirewound.
V1 - GU-81M Tube.
这个最有爱了，用6P12P的小VTTC
