    Is this worth fixing?

    That would have been revealing the most fixable solution, but I remember a Toshiba, one time that a drop had half unseated a muuuuuulti pinned connector.

    Casio PT80 Keyboard - suspected transistor failure

    Sir Charles . . . . . On your units video / audio demonstration: I heard two types of noises, there was the random static pops which sounds like it could be a noisy transistor as it is avalanching / and / breaking down. Then there is the pink noise . . . the rushing noise that you later...

    Can anyone ID this transformer?

    Sir Steve . . . . . OBSERVATIONS . . . On the second unit there is a better appearing pilot light lens cap treatment, I've never seen that compact of a fuse cap cover, the chromed knobs are great too ( its too old of a piece of equipment to be having plastic hot stamped silver mylar film...

    Help with small solar panel setup. Volts but no amps.

    Sir MrPluto409 . . . . . Also the light bulb is working as we tested it with a battery. But you just made the cardinal sin of NOT giving enough analytical information with the preceding statement. WHAT was being the battery voltage supplied WHAT was the DC milliamperes of current, being read...

    How do I see posted diagrams??

    Sir Ben Fun . . . That was an OLD post that just recently got bumped up and revived into activity by a later add on by a person. The host of that image has dropped hosting it since. If you will refer to the NEWEST additions to that post i believe that some info was repeated again and is now...

    Sir Jeanguypataterubberboot . . . . . . . . . ( and I couldn't even START to imagine the 64bit +++++++ password used with that user identifier.) WHEEEEEEEEEEEEEEEEEEEW . . . . what a " luggy" face on that AVATAR. ! Look at your units " POLAR OLD " logo and place 5 finger tips . . . no . ...

    Need Help Rebuilding Hamm's Beer Rippler Motor

    Sir Clark . . . . . . .r . . . . Seems like I now remember seeing these, from starting back in the 1940's-50's-60's and maybe lastly, possibly on up into the '70's ?. THE VISUAL EFFECT: Was being in accordance as to HOW MUCH of an animated area was needed to be created: For a small area they...

    Can anyone ID this transformer?

    On that board portion that you show . . . . .indeed a B+ supply, with a full wave rectifier pair to get initial B+ then an inline HF inductor to an initial 22 ufd of filtering into a 7K filter resistor with a possible like 22 ufd of final filtering. That developed B+ then regulated via a series...

    Can anyone ID this transformer?

    Yep . . . . . that is beeing one cojoined parental effort . . . . . Mom worked in a molasses factory and Pop worked at an arsenal as a hand grenade assembler.

    1970 Delco Radio Repair - audio distorted

    Indeed . . . it is being a much cheaper mono FM radio. The R59 resistor is part of a negative feedback voltage divider loop with its R58 companion. Higher value of R59 . . . more feedback along with lowered distortion, at a cost of overall system gain. Also would want to be sure electrolytics...

    Can anyone ID this transformer?

    Sir Steve . . . . . In referencing the wiring hookup, that the LAST person used: On the transformer primary looks like they could have used O as AC low and an optional 200 or 220 or 240, for AC HI, but instead, he opted for using that far left offset of 10VAC and the 220 to get himself a...

    NPN/PNP double Resistor-Equipped Transistors (RET)

    Look at all of the resistors, their connections and boardspace that don't have to be made if using them.

    Sir Frankchie . . . . . . . . Greetings . . . . . considering us having these initial forthcoming but limited info snippets to work with . . .or against. "repair a 1970 GM am/fm car radio " And will that be AM/FM and FM STEREO and is it also containing tape player provisions ? "a 1972...

    Bose wave radio Not working right

    Sir Caleb man . . . . . Why 'soitanly . . . MULTITUDES . . . . here should likely be able to handle that. You need ALL of the model info for us to precisely identify the SPECIFIC unit . . the cryptic " FORD / Bose" just doesn't cut it in this situation. ( Nor would it . . . .to a Ford parts...

    the prettyLow Drain Flasher circuit with BJT

    Explain how the "LEAKY" 47 ufd electrolytic, being inserted into the power supply input line, to feed the circuitry, fits into the grand scheme of the units design plan ?

    Transistor Help!

    Can we assume that you have searched around the board and seen that there are no other ADKX like Q series units being used on the board. If so, use that one(s) to compare like tests against. Digital transistors with their internally isolated base resistors are a problem to positively evaluate...

    Help Yamaha psr e343 won't stay on

    Woe is me . . . . ., any and all of those units, that I find data on do not seem to have a single " 500 " assigned designator that is being used for the units "electronic power switch" function. What is the period of time that you are now getting the unit to stay turned on, and is that being...

    Transistor Help!

    I certainly don't think so, since they are assigning it a Q prefix before the 259 such that all the transistors are being identified with. How does it test out as being a transistor, as I suggested earlier

    How to open back cover of this TV?

    Sir Mansan . . . . . Wel l l l l l l l l . . . . . I have looked at every for-free manual from Samsung on that size and series of Tee Wee set, yet they all are showing fifty eleventeen back screws that need to be removed to then just let the back easily lift up, off and away.. NOT SO . . ...
