If your the transformer too low current, until you cannot use fully it. It is a pity if you need buy the new transformer. So let’s look at how to modify it to increase current up.
Figure 1 inside transformer have the center trap terminal
How to modify it.
To begin with, remove a paper that wrap a coils out, will be noted that the CT or OV terminal that join 2 wires together. Secondly, separate both the wires apart. Then, renew connect in parallel the coil circuit as Figure 2
Figure 2 connecting coil in parallel
REMEMBER: Do not connect strictly the coil wrong polarity, because both AC voltage like short circuit
When we make sure it is correct, we will get current output is 2 times in old transformer.
