So I have been sweeping a bunch of transformers I collected. I have been using rightmark audio analyzer. I am using a Behringer umc1820 interface. It sweeps two channels, one I just loop back just showing response of soundcard. The second I break out with quarter inch jacks with alligators. After awhile I found with experimenting with different loads I get good results.
I have found that transformers with high ratios like the high impedance as primary and low as secondary. I have seen that too high of load you get peak on high frequencys. I did not do any zobel networks.
I have this Adc out of a gates transistor line amp. Here is the best I could get. With this OT I could not get a very high signal with high impedance as primary. Result of too much resistance in windings?
So this is high as secondary. When done the other way I get massive bass loss and high peak above 10k.
So in the picture here is the low end squirrelyness the result of ringing?
My ratio on this OT is 1:5, or 150:3750.
Anyone ever mess with this transformer or recommend a project for it? Probably a cathode follower?![IMG_20240702_152338071~2.jpg IMG_20240702_152338071~2.jpg](https://cdn.imagearchive.com/groupdiy/data/attachments/83/83717-643eacf4a174830e1bbd247abf089357.jpg)
