Hey Folks, yes, I'm still using this Box and somehow I can't get rid of it.. I don't know what it is but sometimes I like to boost the low frequency band a lil bit (1-2dB) and cut 1-2dB around 10-12 khz on a mix, or when tracking with a Mic that might sound a lil Harsh on some Artists. So i don't do any dramatical, using the Tube Warmth (around 30% - which sound more like an exiter) to add some presence to some signals.
What i don't like is that I hear a lil humming noise around 113hz I think (I need to check it again on the Waves Analyzer), and also, its not the quietest box, compared to my SPL Tube amp or FMR RNLA.. swaping out tubes was the first think i did.. i know don't make that much sense.
I though about the idea that i could try to mod it, i know how to read cap values a lil bit and know how to solder..building a DIY EQ myself is way to much for me right now so i thought about the idea to mod this Box.
So first I found the Schematics of this unit here: http://elektrotanya.com/behringer_t1951.pdf/download.html
1: Somebody on gearslutz modded this Box with Ouptur trannys, scroll down for some pics: http://www.gearslutz.com/board/low-end-theory/656014-behringer-t1952-tube-composer-mod-modification-t1851-t1954-t1950.html
2: The Output Trannys can be found inside the Behringer (4 OT's) Di4000 and i guess 1 OT inside a Di100, i heard some jumper need to be cutted but i don't know which one?? I'm about to buy 2 Behringer Di100 to get those OT's..(if this make sense).
3: I heard some people replace the JRC4580's with AD8599 or LM4562 (I don't know nuthing about it just read it somewhere) some other say "Replace IC 4580 with TI # OPA2134 or TI # NE5532"
Last but not least:
4: Would it make sense to replace the power suply with a Carnhill power suply?? I'm even not sure if this is possible at all ??: http://www.audiomaintenance.com/acatalog/Power_Transformers_and_Chokes.html
5: Is it possible to use Jensen/Lundahl or Carnhill Output trannys instead of the Behringer OT's ?? might need schematics about the Output tranny to answer this right??
Hope some of you can help me to answer those Questions.. I don't want to throw this Box out the Window right now, sure i could get around 100$ for it, but I need an Analog EQ..and also i still like the kinda "Exiter" sounding function, i don't think i can get those many features that Cheap.. :-\
