thanks sp300b, I secured the most important articles for me, especially because I just build the super buffer in order to test him with babelfish J2!

Hi Zen Mod,I take the BC556C for Babel J2 should I take 12k or 4,7k? or measure something?

дају вам никакве проблеме!Ја могу да разумем све!

I made only a small test, before they fell on my right foot.........they had some advantages, not so hot highs, and a little bit more volume, but not the fantastic resolution of the Thiel Koax.now they are waiting for a second try, I will give them when I have finished Babel J2 with your boards, I will try them with one and two output devices.......but even for me being retired it is not possible to work on all frontiers at the same time.My wife finds them much more ugly than the ready made Thiel..... so there is still another frontier to consider...ha,ha

Poor Zen Mod, he always wanted a babel fish for better understanding between people and now he produced a babel shark.. But who knows what a device can do that produces so much enthusiasm, you see AR2 wants us to defend it at any price if someone wants to take it away........Brothers let us build many babel sharks so there is no robbery .....

You see Zen Mod,Your Friends AR2 has not forgotten you ........... How do you feel now after this wonderful description. I hope you read it ten times at least .......Best for you

........ we only got a bit nervous because of the "cone excursion" of tea-bag ------- and it was interesting to hear what Zen Mod suggested what you can do if you want......

I understand!

Dear Zen Mod but we have no fuse that can break when the output is shorted...... :sarcastic_hand:And Semis are expensive..... But my speaker of course more...

Do not disturb him........ He is hearing panoramic and ellipically orbital sound!

Hi Zen Mod, :Viannen_loungelizard: I feel fine, I build up very slowly Babelshark J2 boards you sent me in your generosity......! I am building very slowly to make no faults and to enjoy this building with the feeling to have something extraordinary......why should I change to 4,7k ? Is there less heat in Q7/8?? I have to do it now, because I just do these part. As to the preamp problem, I tried Aleph P with Semisouth R550 but there was no significant change.... but ZVN3310 did a good job! He could stay! The buffers must wait, first Babelfish!You suggested to change J103 in Pumpkin for a complementary pair?Hi tea-bag, happy to hear you are ready with the second channel, so I am eagerly waiting for hearing impressions from you and sp300b! :baklja:

100 Ohm is not a must ....ZM advice is starting with 47Ohm and going up and let the ears decide......A good start for you and the gorgeous Sound for you we heard.....

These JFets are female they like the treatment at the hairdresser ........ I am so eager to hear your impression sp300b........!Do you still hear your Sonido BLH with the 144 driver?

Thanks AR2 I will look for the voltage and install the Zeners!

Hi sp300b, the "poor serbian mans" solution, I don´t have it. I tried the unbalanced, normal version from the DIYforum some months ago with BA-1 and F$ and I liked more my stepped attenuator.But the luxury version of Zen Mod and balanced could be a very good choice, did you hear it already with your J2?

Hi to all builders of Babelfish J2 :Viannen_loungelizard: the outputstage Babelfish is so good that I have a real problem with my pre´s! best choice up to now was always Pumpkin, but this time combined with J2 and 22 Ohm gate stoppers, the instruments image got a little bit to small for my taste, going to 100 Ohm made the size correct. Aleph P had no size problem, but had not the resolution of Pumpkin. Buffer B1 is not bad, but hearing Gregorian chants you can hear voices got more unclear and less detailled. Best solution up to now, but commonly not recommended, no pre at all, only shunt attenuator 10k with Charcroft foils in the signal path and short cables to J2.................. simply marvelous! Most natural sound! May be bass is not totally precise, but all colors of sound are much better, which is more important to me. I suppose the high input impedance of J2 (220k balanced) and the high gain (20db) and as Zen Mod wrote, the very small input capacitance of J2 makes this direct solution possible. I recommend to try this possibility also ............... when you have your building of J2 finished. :headphone:

Oh I forgot,matching the two j-fets?at about 8mA Idss?

hi Zen Mod, only for pleasure I simulated with multisim the two buffers...... at 5 v and 10kH your buffer had only a tenth of the distortion of the B1 Buffer (0,001/0,01) next week I will build up.......hope you had a nice weekend

My foot damaged by loudspeaker cabinet still forces me to stay inside, I need to buy some parts........Next week is time enough ...... Because I just feel tired building things.... Incredible but true.... I must talk a little bit ..... why shouldn't I build four times papas B1 buffer? Or better asked, dear Zen Mod, do you see an advantage in the build with SJ74/Sk170? I see the higher voltage giving more headroom, on the other side it might be better to match four SK170 for a balanced channel than to match a complementary pair. But the feedback in your suggestion could compensate the differences.........Have a nice weekend with your friends........ :Viannen_loungelizard:And tea-bag I am very eager to hear what the matter with your second channel, it got like a crime thriller and we all want to know who is the murderer:........

Very sorry to hear this tea-bag ...... .....After so man different problems one does not know where to start again.........The only thing a I can tell you at the moment..... Don't forget to make a break, until desperation has gone out of the body....... Best for you!Hi Zen Mod, Zhoufang is active again and he offers SJ74 matched, even for the wanted Idss, what would you recommend? He also offers j109, but suppose it will be difficult to put them in the pcb.

I have a ZM collection! PSu must be this one ..... red LEDs.....

o.k. quadro fun for me ......... thanks! :Viannen_loungelizard: :Viannen_loungelizard:

you are again incredible ..... My cd-player output is balanced and the attenuator also. I tried unbalanced, but there is a loss of micro information and space ....

With such a fine amp the question what kind of pre one should use arises once again....... I played with pumpkin, aleph p 1.7 and avc and stepped attenuators shunt type...........at the moment I prefer the last possibility.babel J2 seems to be a very good candidate for passive solutions and I can take a lower gatestopper again and compensate the loss of highs and dynamics a bit.......Dear Zen Mod, what do you use.... ?Can you hear already two channels?

THX Zen Mod, did you get your shuro mox 1 ohm/ 3w?Otherwise I could send you 6 , I have here enough!
