Hi
I have one of these boards surplus so may as well sell it on. I don't have any pictures to hand but it is the same as the board referenced in this post:
https://www.diyaudio.com/community/...ks-mods-and-hints.335881/page-54#post-5971440
and is the one with the round transformers in the photo there. Mine looks the same as that and is unmolested.
It cost £140 two years ago. I'm after £70 posted in UK.
NOW SOLD

Hi, not sure I'm afraid, you are probably best pming bisesik on here to ask to get an accurate answer. I'd hate to give you incorrect info. He does give some info on this thread:
https://www.diyaudio.com/community/threads/output-transformers-for-dacs.327794/page-11
And I guess you can directly message him from there for clarity.
I had already contact with bisesik depending another sale.
Without knowing an exact type I´m not shure if he can tell anything.
He told me to use a 1:16 trafo for the AD1642 with 20Ohm input resistance.
Can you measure input and output resistance with an ohmmeter?

He should know which ones these are I would think as they are the ones he pre-fits to the pcbs specifically for the ES90X8 dacs. Just for clarity, that is what I am selling here, it is one of his hat pcbs pre-populated with the trafos, rcas, xlrs, etc.
I'd have to have a look into that, in this post Brexit world the UK has decided to make trivial things like this remarkably difficult 😕
If you want to PM me an address I can look into it. You might want to get clarity on whether these are what you need first though. I can see just from looking on the underside of the HAT pcb that one primary shows 1:4 and the other 0.5+0.5:4. At least that is what is written on the pcb anyway.

Thx Spev, that´s much to low for my DAC. I´m looking for a trafo with min. 1:15. That´s what´s bisesik mentioned.
Anyway, thanks for your efforts so far.
