    Lock in amplifier EG & G 5210

    My YELLOW star components relate to the reference oscillator processing portions within that PCB. It has the U8 doing the squaring of the SINE oscillator, immediately after its input. Need his confirmation on those parts presences before posting schematic with its signal flow mark up. Thus...

    Lock in amplifier EG & G 5210

    Sir rags . . . . . See if the unit will work with using the TTL input beside it, or use a function generator, in square wave output mode, set down to a TTL level of output. Also see if this parts used layout is akin to your unit, with U8 being an LF311H on your unit.. REFERENCE . . . ...

    Help to identify component

    Sir +Turbo . . . . . Well then, do you minimally have . . . . . or have access to . . . . .a DVM, to be able to test that one diode and see if it is being dead shorted . . . . or being open circuit. As well as your photo can show, I could conceive of that being used as a directional device...

    Car Cd Player AUX input

    Sir SilviuMerlusca . . . . . That shot without the other side is meaningless . . .see if this 300 series Blaupunkt might be using the same audio IC's , with the audio oriented ones being those in my YELLOW boxes. That would then let us orient the left and right audio inputs connections to...

    Yamaha rxv 465 no display and no power..

    Sir Hermant Choudhary If you are . . .that means that you must have found and cleared up the direct short to ground in the Q400 circuitry area. Was it due to poor soldering . . . . or solder spash(es) ? REFERENCE POST 31 Mini Schematic . . . . . So now you can plug in the unit and turn on...

    Capacitor or Diode?

    Sir jakeofalltrades12 . . . . . Agreed . . . . . . that on the negative lead of that tantalum capacitor, that you pulled off a pad from the top of the board. I'm going to place its value at 3 DECIMAL 3 ufd and at 25 VDC working. Ref . . . .your center photo . . . and concentrating on the caps...

    Need Help regarding Yamaha RXV371. No Sound Output

    Sir MarkHu . . . . . Seems like he didn't come back and elaborate, my end comment was relevant to not even knowing of what his problem was and if he even HAD any 7VDC supply. In your case you say that you HAVE that voltage present , but with it being high. I can give you this start off...

    Fence flasher

    Sir frans . . . . . Everything that I have seen mentioned is WAAAAAAY - WAAAAAAAY - WAAAAAAAY too invasive and demanding of loading down your chargers HV output voltage from the unit. Instead, how about considering the use of a resistor HV divider string , a neon lamp, a photocell, a LED...

    Repairing a burned-out Flash Unit (screenprinting)

    No . . . . unless you want to jury rig up an incandescent lamp load in series with with 120VAC to then be able to visually confirm the SSR secondary's operation. That's for certain. How about having the unit totally AC power input free and use an ohmmeter to measure between the left terminal...

    Realistic STA-2100D

    So you still have a unit that plays, but has : what I thought was transformer hum . . . . . being superimposed in the background. If so, does running the volume down to absolute zero, decrease that HUMMMM level ? Or if that doesn't quench the sound can you take an ear and get in close and...

    Realistic STA-2100D

    That's why I specified the different associations of the 1-2-3-4 fuse positions. If fuse positions 1 and 2 were not the ones blowing, and positions 3 or 4 were, that points to an overload situation with the circuitry of those last two fuse positions. Thus, leaving your 1 and 2 fuse positions...

    Convert a wall sconce to a plug-in.

    Mme Janice 221. . . . . There is a 50/50 chance that you have already done it the safe way. The WIDE blade of the plug and its connective wire is the designated grounded (safe / non shocking) side of the AC power wiring. . . . While the NARROW blade and its connective wire is the HOT or...

    Convert a wall sconce to a plug-in.

    Are the blades of the plug, both of the same width, or is one wider than the other ?. The loose wire would be a grounding wire, for going to the ground connection within a hard wire junction box. (Your answer to part 1 will determine its future use.) And do you have a black and a white wire as...
