all good, but output capasitance 60pF vs 11pF.

Hello all! Now FJPF2145 obsolete on Mouser. But I need to finish my T2. Where it is possible to get or how to replace them? What you think?

Not exactly resistance - different lengths of second's wires. Very pure sound after this TVC, especially on low level volume.

PSU for both: Carbon and GG (Ground Grid). With delay board for tubes filaments. Compact 22AWG wires can handle 700v DC, double shielded.

Read many good reviews on such kind of DACs, so get latest version of boards dam2941-12. Wanted to power it with Salas Reflektor-D and Salas UltraBib.b.

And what difference between CFA3 and Dynahi? My balanced Dynahi seems more rude, more simpler then beta22. Last one very close to electrostatic sound.

Have you heard beta22?

I just had 2004 boards from another guy and finished the project. And I am not sure what is the best for isodynamic headphones: CFA3 or Dynahi_2004.

Assembled my balanced Dynahi old version of 2004. Using it with HiFiman HE-6. Sound: entertaining, opened, dancing cheerful. Compared it with beta22. Have only couple of questions: * does it make sence to change main capacitors from Panasonic FC 470uF on Nichicon KG 680uF * DC offset without opamp +-10mV, with opamp OP27 +-2mV. Is it ok, left as is or try to make it better by changing on opa134 or something like this * does it make sence to make some other mods What you think?

Not so far ago it was expected in JUL-23 on mouser, but now shift to 19-Aug-24. So only stn0214. here said https://www.mouser.com/PCN/onsemi_Generic_PD24419ZB.pdf it could be replaced on FQP8N80C, but mouser also suggested STP8NK80ZFP

some intermediate results of PSU (followed by jamesmking assembly) Used 0.5mm transformer wires for AC HV (red ones): compact and reliable.

tiny mistake: FQPF8n80s -> FQPF8n80c. But anyway, FQPF8n80c completely obsolete. May be it make sence to change it on FQP8n80c. PS: compared to previous gerber version fixed wrong silk for IXCP10M90S: KAG -> GAK, good 👍

very strange, now mouser shows for IXCP10M90S

Mouser has changed delivery date for IXCP10M90S on 08-Aug-2023. So where to buy it?

I have 4 sets of T2 boards of morden jamesmking's design. If smb wanted just pm me.
