Comming soon...after test this kit...😉
hi electra_in,
nice work electra in.
which 220 diode ur going to use and the relay?
Now, I built this PA EA4500w by Cheshtap. This progress:
hi electra nice work can you tell me what method you use to print your pcb it looks very nice
which price your pcb, i am order from you cheshta and please deliver pcb layuot at rdlmedia@yahoo.com thank you friendFR4,1.6mm,2 layer
primary in parallel
secondary in series
i'm not an expert,just sharing
somebody correct if wrong
but i think this will help😀

hi engel dela pena thanks for the reply.
one question, is the two transformers stick to other one or any distance to other transfomer.

make sure you get the phasing correctly....
you can connect the secondaries in series as angel said.....
connect that to a low voltage ac source, say a 12 volts and then when paralleling the primaries, connect one side together, measure the voltage on the free ends, it should be zero, otherwise reverse the leads and then you can finalize the connections...
make sure to mark the ends of the leads so you know which goes to where...

nazirdi,
you should be thankful to sir tony
see how this guy dig so deep regarding transformer

primary phasing is important,sec phasing affect by pri
i remember how i deal with this before
some macrotech amp transformer(burned) my friend told me to repair,
i can no longer record any data it is filled with something like aspalt,if rewind you have to make new calculation and connection,so i end up something like your connection,parallel pri series sec.
same problem as yours,
i have a practical approach of using small copper wire as fuse during testing connection if there is something wrong small wire surely blow like fuse blow.

hi ravpreet
you can find it in lr market shop no 393 for around 180 rs.iam sure you dont have to anywhere else.

here another Class H stepdriverfor engel dela pena
I think Mosfets as Stepdriver to prefer is better compare to BJTs
