Coils for WD25T EX

[hwaitung]

I am planning to build the WD25T EX, but it seems that it is not easy to match the DCR of the coils in the plan.

My question is how much can we deviate from the DCR values? Is it better to go for higher or lower DCR if there is no exact match?

Can we do some adjustment to the circuit if DCR is not the same? e.g. the treble coil L2 is in series with R5, can we adjust the value of R5 to compensate?

Thanks in advance!

It should be possible to obtain inductors wound to the exact specification such as from Jantzen as linked here.

Of course, I appreciate this link is from a British supplier and you are in Hong Kong, but it shows that ordering exact specifications is possible.
