    Old RCA CRT Console TV Repair

    Important notes.... The colortrak system was one of the first systems that used signal to the vid flyback circuits. Up until then the flyback on the tube was line voltage. No... I haven't ever done anything or built any or have I had anything to do with RCA, since they stole my ppl circuits...

    Mercury 80 throttle.

    The unit is off a 75hp. But.... It's just a throttle right!!!??? This is a 250v AC, but it fit the pins on the mount... Where can I get the right switch? The switch is activated by the big piece on the left of the pins... Second and third pics are when the gear is in forward or reverse ... I...

    Calculating draw current

    How about this.. heh heh?!, a lossy signal at 35v and .5 amps will have how many amps when it reaches 6 v ??? Or... If 35v has .5 amps in an induced current, how much amperage will it have at 6v?! That was great! Thanks, you could have just said "ohms law", and called me an idiot. Thanks...

    Calculating draw current

    If my transformer bottoms out at half an amp with a full load of 35v, how did I calculate the load capacity of the transformer at 6v?

    2hp motor hums and not turning

    I think my new phone has cooked windings too... but I will test the caps to be sure.... Note: this is a new phone. yeah ! @73%(*$ motors are probably for recycling.... replace the motor and the capacitor starter... make sure all the specs are exact, and paint it hot red or green, draw a...

    Samsung smarty fridge... no cooling

    yeah yeah... it didn't work!, the fridge didn't still didn't cool off, but we also know that with CPU operated boards, sometimes it takes many restarts to reboot the system. So I am looking for a nice replacement for the inverter. I VOM probed on the tops of the large capacitors on the...

    Grounded inverter circuit board

    The inverter board capacitors are dropping lots of AC and DC from their tops to the frame of the refrigerator. I was told to replace the inverter board. K I wanna find out why! What would make an inverter board do this?

    Samsung smarty fridge... no cooling

    Deep and dark are the caverns we creep... and near the crevasse' to thin for us to skweeze through... We find that a component is designed to stand and deliver 2.4a without a sink and 6a with a sink.... I doo miee dishes weekly whether I need the sink space or not..... And if a really great...

    Mosfets as voltage dividers.

    I noticed the amperage issue. I want a higher amp ps. Thanks. You have acknowledged all my worst fears!

    Wall wart readings

    I am presuming the Wall wart is.bad... it's a 7.5vdc 1800ma but meters at 0.00vdc. with a 22ohm load it reads 1700ma, bot only 1 volt. Does that mean it's time for the junk pile?

    Mosfets as voltage dividers.

    The 2N3055 transistor. I will probably need a few other components.

    Mosfets as voltage dividers.

    Yes I have copied the schematic... Now to paste it...ok. The board that was in the device was not this one, but had many of the same components. I tested the transistor...two diodes. Don't know what that means.

    Mosfets as voltage dividers.

    Oh.. the reason why..... Lost my photos of the board...dismantled it... It needs a new transistor, and the OEM posted only an upgrade schematic for the model.

    Mosfets as voltage dividers.

    Ok. Sorry.

    Mosfets as voltage dividers.

    I see a lot of yootoob videos where a guy wires up some pots and some resistors and diodes to some mosfets, and builds a voltage and amperage controller. I am rebuilding a bench ps and was wondering if this would be a good circuit to put in for variable power and current?

    LCD driver: What changes in 3-D mode?

    Everybody missed it. When the problem overdrafts the solution the conclusions become moot. Idealize if you will a screen that has multiple layers of screens. Then position the elements that deliver the picture so that they are relational instead of absolute. Now with the screens on short...
