I will send it to you if you email me. STi5510 and STi5518 [email protected]

I found the same Info on Electroda MPF970 P-Channel JFET Motorola 2N3993 2N5114 2N3993_2N3994.pdf 2N5114_2N5115_2N5116.pdf

Send detailed Pictures of the board and we may be able to make a schematic from it. You know Reverse Engineer it.

I also moderate Circuit Request board.

And here are a couple from our project section. http://www.electronics-lab.com/projects/motor_light/024/index.html http://www.electronics-lab.com/projects/sensors/001/index.htm

Here are more

We could get similar Circuits for you but that one is proprietary.

I fixed it for you Steven. You don't need to ask MP in my Forum.

Here is another copy in PDF Nice Job by the way. Looks Great! ;) FPT1010.pdf

Compare the datasheets. The 74HCT240 is CMOS and Static Sensitive The 74LS240 has More Power Consumption. The Pin-Out is the same and it may just work. 74HC240_74HCT240.pdf DM74LS240_DM74LS241.pdf

Here is the real stuff. http://www.allaboutcircuits.com/vol_1/chpt_1/7.html http://www.mi.mun.ca/~cchaulk/eltk1100/ivse/ivse.htm http://www.qrg.northwestern.edu/projects/vss/docs/Power/2-whats-electron-flow.html

Is this the picture you are looking at? They have written books about the way Electricity travels. Lightning for example goes from the ground to the cloud. Everyone thinks it is the other way around. But, if you film it with a slow motion camera you will see that it goes up not down. http://www.sunblock99.org.uk/sb99/people/DMackay/lightning.html Here is more on how electrons flow. http://www.allaboutcircuits.com/vol_1/chpt_1/7.html http://www.mi.mun.ca/~cchaulk/eltk1100/ivse/ivse.htm http://www.qrg.northwestern.edu/projects/vss/docs/Power/2-whats-electron-flow.html

http://www.kpsec.freeuk.com/components/74series.htm#74393 7490 decade (0-9) ripple counter 7493 4-bit (0-15) ripple counter NC = No Connection (a pin that is not used). # on the 7490 pins 6 and 7 connect to an internal AND gate for resetting to 9. For normal use connect QA to clockB and connect the external clock signal to clockA. These are ripple counters so beware that glitches may occur in any logic gate systems connected to their outputs due to the slight delay before the later counter outputs respond to a clock pulse. The count advances as the clock input becomes low (on the falling-edge), this is indicated by the bar over the clock label. This is the usual clock behaviour of ripple counters and it means a counter output can directly drive the clock input of the next counter in a chain. The counter is in two sections: clockA-QA and clockB-QB-QC-QD. For normal use connect QA to clockB to link the two sections, and connect the external clock signal to clockA. For normal operation at least one reset0 input should be low, making both high resets the counter to zero (0000, QA-QD low). Note that the 7490 has a pair of reset9 inputs on pins 6 and 7, these reset the counter to nine (1001) so at least one of them must be low for counting to occur. Counting to less than the maximum (9 or 15) can be achieved by connecting the appropriate output(s) to the two reset0 inputs. If only one reset input is required the two inputs can be connected together. For example: to count 0 to 8 connect QA (1) and QD (8) to the reset inputs. Connecting ripple counters in a chain: please see 74393 below. -------------------------------------------------------------------------------- http://www.kpsec.freeuk.com/components/cmos.htm 4029 up/down synchronous counter with preset The 4029 is a synchronous counter so its outputs change precisely together on each clock pulse. This is helpful if you need to connect the outputs to logic gates because it avoids the glitches which occur with ripple counters. The count occurs as the clock input becomes high (on the rising-edge). The up/down input determines the direction of counting: high for up, low for down. The state of up/down should be changed when the clock is high. For normal operation (counting) preset, and carry in should be low. The binary/decade input selects the type of counter: 4-bit binary (0-15) when high; decade (0-9) when low. The counter may be preset by placing the desired binary number on the inputs A-D and briefly making the preset input high. There is no reset input, but preset can be used to reset the count to zero if inputs A-D are all low. Connecting synchronous counters in a chain: please see 4510/16 below. -------------------------------------------------------------------------------- 4510 up/down decade (0-9) counter with preset 4516 up/down 4-bit (0-15) counter with preset These are synchronous counters so their outputs change precisely together on each clock pulse. This is helpful if you need to connect their outputs to logic gates because it avoids the glitches which occur with ripple counters. The count occurs as the clock input becomes high (on the rising-edge). The up/down input determines the direction of counting: high for up, low for down. The state of up/down should be changed when the clock is high. For normal operation (counting) preset, reset and carry in should be low. When reset is high it resets the count to zero (0000, QA-QD low). The clock input should be low when resetting. The counter may be preset by placing the desired binary number on the inputs A-D and briefly making the preset input high, the clock input should be low when this happens. Connecting synchronous counters in a chain The diagram below shows how to link synchronous counters, notice how all the clock (CK) inputs are linked. Carry out (CO) feeds carry in (CI) of the next counter. Carry in (CI) of the first counter should be low for 4029, 4510 and 4516 counters.

Here is the best I could do. an3814k_Spanish.pdf

I have NAD3240PE

The frequency of the ultrasound is approximately 80 kHz for this unit with a maximum amplitude of about 460 VAC RMS (1,300 V p-p) for a 115 VAC input. OOPS I Did forget :o

LOOK AGAIN I think you are looking at the first not the last because I did correct it!

KAC624 Kenwood Car Amplifier Service manual NEEDED Please Upload If you have it. I have a Kenwood KAC624 that has the Audio Output Transistors burned out. D2065 is the number stamped on all of them. I thought it kind of strange they would all be the same. Usually you would have an NPN and a PNP in each channel. I would love to get my hands on a schematic for this model. Other Modles above and below in model number have a different configuration. I need a Schematic for this model Number. Any help would be appreciated.
