So Generg like BBA3 with single pair on outputs and a trafo on input.
You still using F4 without input Jfets? How about smaller ratio stepup trafo?

O.K. the holes of Shunty are still in the case, so a try is no problem! 🙂
and I have no problems at all to put any new board in my pre..... there are so many holes from the last 3 years and from about 5 different pres and different attenuators, that I can put any gadget in and find the fitting holes immediately..........😀😀😀😀😀😀😀........ music with BBA-3 has a very good depth and athmosphere .........even when I use it balanced in and unbalanced out for my F4.

Hi Buzz,
at the moment I have the FETs again in front of the xformer.....
reason...... I have a 10 k TKD stereo pot at the unbalanced output, so I wanted to keep the 100k input of the F4.
The TKD is unfortunately much better than my expensive balanced 10k stereo pot consisting of an Elma switch and Takman and Vishay foil resistors, but exists in my version only unbalanced.
Maybe after some time I take simply two and regulate a bit more.....
smaller ratio stepup is a problem, I have to buy a new one and they are often expensive.....
not now .
I'm Paypal-less .
long story , about livin' behind Iron Curtain
I'll just use power section of DCB1 i have sitting around unpopulated.
I think you told me before, but why have the pot after the Ba-3 instead of in front.
because I go from the cd-player balanced out........ balanced in BBA-3 and I have only a simple stereo TKD Pot....sounds better....
you know - there is always cheap solution - put some elco caps on output
you can shape your own sound , depending what type of caps you're using

I did think about that initially. But then, the control over the sound would be very little as compared to an active solution. But then, what's wrong in trying the cheap solution first. The BA-3B won't go a waste because I want to use them with crippled F4 to drive Fostex 168Sigmas in Quarter Wave Tubes.
BBA-3
what I can say to the qualities of BBA-3.......😀
I have a Meridian CD-Player with balanced and unbalanced output....
with BBA-3 the difference between balanced in and unbalanced in is very very big......!
Such a big difference was not to hear with Aleph P and even Pumpkin(g) my favorite pre...
conclusion....... 1. the balanced input of BBA-3 is the best I ever had.😀😀
2. the unbalanced input of BBA-3 is the worst I ever
had...😱😱
3. ...... (fill in yourself and tell me)..................🙂
and a question I cannot answer....
using the BBA-3 unbalanced in and out is the same thing as using a simple BA-3 or is there still a difference?
shorting the in and outputs of one half makes this half dead or is the shorted half still of any use for the activated half?
I am so dumb that I belong to the dump...... 🙂🙂🙂

ya see that common resistor between sources of two halves ?
make it from 100+100 ohms , then route their common point to gnd via switch
when you need unbal in + unbal out , flip switch on , then use just one side
or you can use both for stereo
or you can make 4-channel Home ooking theater of it
bal stage is good for converter duty , but can be lousy when flapping side needs to be virtual ground for active side
that can be the case here ....
even if only Pa can confirm that fully ...... like always , I'm here just for public disgrace

Thanks Zen Mod the switch is a very good idea to test the sound difference between a half dead BBA-3 😱😱and a complete alive BA-3! 🙂🙂
