ok thank you FRIENDS !
after I answer this question I am going to weld.
why i see in a maual board this :
Eyelet #4 & #5 to Pins 1 & 2 of the left power take-off socket (Note 1)
(i have soldered 2 and 7)
NOTE 1: These are the input tube filament connections. A stock ST-70 uses the front panel power take-off
sockets as a tie point for the input board tube filament wiring. Many amplifier modifications use these
socket holes for input jacks or other purposes. If the tube filament power is not present on these jacks or the
jacks themselves are not present, then the filament wiring can be run (as twisted pairs to reduce hum) from
the output tube filament connection (EL34: pins 2&7). The phase inverter position (V2) now has extra flexibility to use tubes with different pinouts, to use 12AU7, 12BH7, ECC99 solder a wire from J1 to J2 and make your filament connections to eyelets 24 & 25, to use 6CG7, 6922, 7308, or 6DJ8 do not jumper J1 and J2 and instead make your filament connections to J1 and J2 and ignore eyelets 24 and 25.
