EmRR brought up this in another post where I left topic by complaining about having lost a precious GZ34 due to low DCR of modern power transformers:
The upper GZ34 issue is easy to fix with 2 fat serial resistors of 50 - 100 R (and probably has no big effect on proper function).
But had the same experience EmRR mentions with modern audio transformers (and plate chokes). I suppose, it's not that easy just to use two parallel resistors to reach the original DCR .... and then have original behavior and sound. Of course core material is different today and I think frequency response on modern transformers is usually better. But how to get to original behaviour in theory ?
https://groupdiy.com/index.php?topic=76670.msg974470#msg974470I haven't thought about that, it's certainly the case that audio transformers now versus then use larger wire with lower DCR, and it makes things like tube compressors behave and sound differently than the originals they 'clone'.
