Iron Pre SMD Balanced Supplemental Kit

This was a fun build with some minor challenges for this newer DIYer with very limited EE knowledge. But with help from the community it all worked out.

The SE IronPre sounds lovely, even after just a few days of use. It replaced an Elekit TU-8500 (tubes) in my rig (with Elekit TU-8900 [2A3 tubes] and Zu DW6 spkrs). The IronPre presented clean open and perhaps more delicate (in a good way) sound, with stronger imaging. Still breaking in, but very satisfying so far.

I was still plugging along with the single ended iron pre when this gem came along. I have balanced equipment too, how can my long suffering wife deny me? Finished the honeydew list first. Well I already ordered the chassis also. Now to finish the SE version first.

I recently completed Iron Pre-SE. Build process was straight forward (excellent build guide). Parts, boards, and components are top notch. Frist, I have completed power supply, then in-put section and finally buffer and transformer section. All went smooth without any single problem, works for the very first moment.
Connected to my beloved mono’s Aleph 2 (jumper at 12db), followed by Monitor Audio Platinum 100 II bookshelf, this “little” gem shows it’s full protentional. The sound is just phenomenal…
Thank’s to Zen Mod and ItsAllInMyHead for sharing yours’s knowledge and passion to this community.
All the best,
