Sir cASSetteMan . . . . .
Initially . . . . just like, as it was in the Duuuuurty Harry movie . . ." I
GOTS to knows ! "
Now . . . .would C

mAN be your younger brother, older brother or fraternal twin ?
You did not initially have the
WHOLE inclusion of the pilot lamp wiring path.
Looks like you need a wee bit more of the puzzle exposed, in order to ascertain your " lite bub " conundrum.
That specific schematic snippet is now redrawn, and being shown below . . . for . . ."The Rest of the Story" . . . . .
A LAMP CIRCUITRY WALK THRU . . . . .
Being at the schema far righty center, is the T4 power transformer with only its low voltage secondary winding visible.
Low voltage AC leaves the top of the winding and routes up to the tuner board above and goes in at the PS2 connection and then comes back down thru the PS1 connection . .
IF . . . the power switch was being on, then AC passes down to the regulator board and the AC1 input and then a flow thru, over to the DF-02 F
ull W
ave B
ridge rectifier, and along with its C47 support capacitor, is being used to create the raw low voltage DC to power the receiver.
Then there is the use of Q9 transistor for supplying the regulated 10 VDC, with its take off, being from its emitter.
The Q8 transistor is supplying the regulated 5.6 VDC, with its take off point being from its emitter.
The receiver should now have its DC power and typically be working with those voltages present.
Back to the lamps AC supply at the AC input, the power routes down to the
YELLOW BOX option area of then using the J7 jumper for a direct feed thru or, if left opened, the path is being thru a R58 dropping resistor . . . . as a "bub" saver . . . . if it is using that option. You analyze and figure what manner it uses.
The AC then goes into and out of the lamp.
THE LAMP . . . .
Is being a 14.5 v @ 115ma lamp . . . . and only you can see if any specific mechanical conditions & connections are involved . That current consumption is being on the low end of expected norms, plus there may be heating restraints considerations , so that nothing in close proximity nearby gets scorched.
Now, if you query
YAMAHAULER supply , you will be finding an out of stock condition .and with their not knowing when ? if ? ever ? it is being available again.
Sure, there is probably someone lurking on Ebay, with bated breath, that has an original N
ew O
ld S
tock lamp .that you can have for $50 plus $24.99 Pony Express shipping and handling fees.
A CIRCUIT FLOW CONTINUANCE . . . . .
The AC flow path out from the lamp passes up and over to the AC 2 terminal and then feeds up to the bottom of the transformer secondary winding, to have given a full power flow thru path.
SOLUTION . . . . . .
If all of the AC power supply path is complete and you merely have an open lamp.
IF . . . . . being my puppy to groom . . . . . I would decide upon the desired lighting color, brightness and light beam spread that it has to create, along with mechanical mounting considerations and manner of wiring lead connectivity.
The
RED BOX area shows the utilization of a series 1/2 watt dropping resistor and a one way directional steering diode to utilize only the positive nodes of the AC supply and a LED for the illumination task .
YOU . . . being able to observe the mechanical and mounting aspects . . . . lets you solve the associated electro mechanical aspects of using a LED for illumination instead of a limited time of use incandescent lamp, such as it was.
The LED conversion should result in an expected half life of 3 eons.
PLUS . . .the power transformer should just . . . . .
L O V E . . . . you for the loading that you are additionally taking off from it.
Thaaaaaaaaaaaaaaaasit . . . . .

I just love to go shopping, and while I am there, I love to freak out salespeople and totally mess with their minds.
They always ask me if they can help me, and I say, "Have you got anything I'd like?"
Then when they ask me what size I need, and I say, " Extra medium."
