Kain, Welcome to this community. The analog meters are more expensive than the digital these days, are you sure you don

Here is part two! Ante ::) [attachment deleted by admin]

balder, I tried but I got error messages so now I have split the file in two and try again! Ante ::) PAN_tc-28x1c_25x1c-1.pdf

Rhonn, Basically a higher voltage gives lower losses and you can use thiner wires for the same power (W). And higher frequency will give you smaller transformers and a slightly better picture on the TV-set. AC is better than DC when switching (Less arcing 8) ) and changing the voltage at home with a transformer. (Don

balder, It

To all, If there is a transformer inside and it

Chaos, Welcome to this community. Here are some really simple circuits to start with if you are trying to learn a new software. http://www.tep.org.uk/upload/112%20circuits/ Ante ::)

audioguru, Seems like prototyping days are over and the device is now ready for production ;D. How long time do you think the triple A batterys will run in this final version? Ante ::)

balder, I have service manual 10 page (mostly schematic) for TX-28X1C / TX-25XIC TX28X1CP / TX-25X1CP ALPHA I don

FATOOTA, They come in many different shapes here is one example: Ante ::)

audioguru, I think you missed the sketch, or I am having a problem here! :o Ante ::)

Vainajala, I think you should stick to the TO3 and either move it from the pcb or fit a heatsink like this: Ante ::)

vainajala, The LM 7824 can take 40V input so I think it will work or I can use the LM 317HV. Thanks for bringing my attention to the MAX 4080, I have not seen it before and it

vainajala, Looks good to me, If you can fit a heatsink on the TO3 your home free. I can

John, Is this the right thread for this circuit John? Ante ::)

Vainajala, You have been busy. Thanks! I have been sketching on something similar and I used the wire from the PCB

audioguru, I tried not to interfere but now I could not resist any longer, tell me is your next step to chase ghosts ? Ante ::)

geeko, Welcome to this community. ;D There is lots of info in the datasheet. http://www.philipslogic.com/products/hc/pdf/74hc390.pdf Ante ::)

ZomBIE, I always wondered where 8) CIA 8) purchase their stuff, now I know! Ante ::)

mihpa, I have used an 8A transformer so I can say for sure that it is enough, but maybe a 6.5A will work. If you have one lying around, try it and you can report back if it works. The reason I chose an 8A is that there are very high currents when switching and a 5A transformer will not give you 5A out from this circuit at least not in the higher voltage range. Ante ::)

mihpa, I have built this circuit and it works fine. To feed this circuit you need a transformer (28V 8A) and a rectifier (20A). It is not necessary to stabilise this. Yes you can adjust the output voltage 2.5

cwt, It is MAXIM ! Ante ::)

Vainajala, Looks good to me, I would hook it up and try it! Ante ::)

vainajala, I have Proteus but no model for the TL 494. :( Ante ::)

Vainajala, Don
