Looking for a 600:600 ungapped OT. As a (cheaper) alternative to Carnhill VTB 2281. Does UTM have something like this? I don't think I see it but I'm not a transformer expert..
 
The UTM Transformers work also perfectly with Abes Pye Compressor Clone PCBs. Input TX, Output TX and for the Sidechains are all from UTM . Verrrry gentle and expensive sounding pieces. Crystal clear, transparent and detailed, brilliant highend, lowend is super well balanced in my opinion.... Really flashed about the audible results of these Transformers in this build..🤌

Hi All

I'm planning to move forward on finishing ML12 pre but I'm confused how to wire the 3503 TX ! he's supposed to be a 2503 replacement but I cannot understand how to wire it !?

I'm also confused that EA2503 is 75ohm Primary and on the 3503 diagram is mark 150/150 and below on text it's write : Impedance: 75: 300, 300: 300

or will you recommend going with a 3523 which is 75/300?

could you help me understand !

thanks !!!

Hey Igor, we emailed a few days ago about the UTM3581s, but I haven't heard back from you about how to place the order. I know you're busy, so I just wanted to give you a bump in case my message got buried. No rush!
 
What is the price of the #2622 transformers?
The permalloy cans are quite expensive. We buy them in Japan, 10€ each at 200 pcs. batch.
I'm afraid, the final UTM2522 transformer price will be about 49€.
The first transformers for testing we can ship in 1-2 weeks. The mass production we can start in 4-6 weeks.
Please also note, that our can is 4 mm wider (dia=34mm) than the API2622. You need to verify your PCB space.
