Post Subject: More HF from a transformer and DHT?Posted by Romy the Cat on: 6/6/2009

I found an interesting flow in the sound of my current OPTS and while it will be certified I am experimenting with park of amorphous core transformers that left over from my former projects. I am trying to remap my Tribute but it is just 40mA. It might be enough for RE604 and YO186 as the run at 35mA but it is not good for 2A4 as some of them go up to 40mA. I have 50mA Lundahl 1623A that I used for my failed headphone project and how use for my fundamental channel. The leading battle is a very interesting amorphous transformer. It is 5-6H, make custom for me with limited turns, specifically foe my DSET configuration. It uses a large core and can handle even 100mA. I kind of slowly am experimenting with them.

At this point I very much know what I need I need – I heed the HF extensions, not the response itself – all of them are good for couple hundreds of kHz according to measurements but I am looking for the subjective auditable HF extensions while the transformers are running the “soft” DH tubes. I almost looking for a “bright” output transformer, sure if I found one then I will be bitching that it corrupted my DH’s “butterfly effect” (read above). Still among the few transformers that I have in THIS specific configuration I like more those that give me more HF from my DH tubes. Can I blame myself?

The key I see in this that with more “punchy “extension of HF from my MF channel I can implement the Macondo’ drivers integration model that I would like to. Otherwise it will be not the best case in my application. I always have my full range Milq (injection channels) with amorphous 6C33C that give me an idea how fur the S2 driver might be taken…
