Why are you bummed? The BA-3 is, unquestionably, my favorite of the DIY Pass amplifiers. Build it. The amp is amazing. 

I'm looking for a balanced topology.. But DC coupled
I'll do it anyway.. Since I don't have a balanced pre-amp.
Should I get the 2sk2013 or just 9610/610 is good enough?

510/9510 or 610/9610 are good enough
2SK/2SJ are slightly better ....... but only of you don't need to invest kidney or year's time to find them

Kidney for 72 €....? Octett

Last three sets from NicMac here
2SK2013/2SJ313 matched pairs and quads

Wonder this works with a output transformer? There is a iso tango for sale
5k 10k :600 ohm
40ma max
Still need coupling?

I just bought a bunch of 2SK2013/2SJ313 from Quest for $1.48 a piece. I bought a few on a lark to see what the counterfeiters were doing, but when they turned out to be real I bought a bunch more.
They don't show them in inventory anymore, though. I'm pretty sure I didn't buy them out; maybe they're just adjusting the price?

Hello Jeff,
What is Quest?
I would like to have a handful of this little wonders myself for my headphone amp.
And ... Ba3 has ever been bridged instead of balanced? (because a true balanced source is rather scarce)
when you have BA3 Balanced amp , you can drive it with SE source , as any (proper) balanced amp, or amp having balanced input - just short pins 1 and 3 of XLR input , while using RCA jack
in other words- short neg. input of amp to GND
of course that you need pretty much same voltage envelope on input , as in case with balanced
FE of amp itself is doing SE-Bal conversion

But they're still showing no stock.
B&D have the 2SK2013, but they're not giving them away like Quest were.

Not seeing them on Spencer's page...am I missing them, or do I just need to contact and inquire?
