WTB: Jensen 1:1 Transformer (PO-2XX?)

I keep forgetting the various designations, but I'm looking for the 1:1 version.

Look near the top of Marv's post.

 

Thanks, but seems like a used Jensen would be cheaper.

@ChaChaRealSmooth told me yesterday that this model does degrade the audio a bit and gives lower gain. Might want to double check on that part before proceeding.

 

That's the 4:1 I believe.

 

Someone turned me on to this: https://www.bhphotovideo.com/c/prod...r_line_input_isolator_2_channel.html/overview

Which is 1:1 but I'd still like to try and get a used version. Also, after a little reading seems the PO version has better bass or something, while the PI has better EMI/noise rejection. Frankly sounds like nervosa coming on...

 

Yeah I was recently looking at these too. The PO and PI are both 1:1 but look at their input impertinences:

PI-2XR (Min 22k Typical: 23.5k Max 25k) and PO-2XR (Min 670 Typical 680 Max 690)

I was worried my GMB A1 might have issues as I had read Yggdrasil and GMB A1's had trouble with 600ohm loads. Looks like you have a BF2, I'm guessing it's better like the A2's of it's bigger brothers but not 100% sure.

I ended up finding a great deal on a used PI-2XR, wanted a PO-2XR but was worried I might run into issues. And like you said it's more than likely mostly nervosa anywho.

 

I had the PO-2XR, it's the 1:1 version that interferes the least with the signal. I sold it here previously already but will link my old thread for reference. You can buy it directly from Jensen for about $285 if I remember correctly.

my suggestion before you spend $200+ on one of these which are really meant for professional applications and not audiophile ones is to DIY

you can get 1:1 line transformers from eastern europe for as little as $60/pr. IMO, they will have better sound character than Jensens. add a small case and some RCA/XLR jacks for maybe $30. you will have something much better for $100 than the Jensen.

just a suggestion! of course Jensen sells their own line transformers separately from the isolator boxes but these will be $140/pr, not really worth it.

 

I don't doubt it, the issue for people like my self comes down to time! So it would be cool to see some one with more time and experience who may be able to build one of these.
