Looking good, guys - great progress Any listening impressions from the get-together? Nige, what regulator are you using? Does it stands up well to the near short circuit of the caps when depleted? Coz all the regulators are in series we opted for plastic backed regs to save worrying about shorts on...

Dc offsets are circa +/- 2.75v on the differential outputs at 133ohm iv
Think it's either 800 to 1000mv output ac

Am I right in thinking if I introduce a negative supply I can use the same fet buffer on the negative output to drive a traffo without caps?

good stuff, best of luck

I had a look at it a while back when I was designing I/V for my own DAC. While I like MOSFETs in I/V stages this one seems to waste a whole lot of power by running f...

just thinking out aloud
abrax what you think of this?

Abrax if you draw up a mosfet output iv and or filter ill try set it up for sat when the lads are down

We were talking about srpp valves in the background but my knowledge is almost zero of such things

I though when I put a transistor on the output of my batt tda1387 the difference wasn't huge

I was hoping that using a traffo to convert differential to single ended would bring us far enough

133r
I've got 2 270s in atm
If I remember right anything between 100 and 150r seemed to work just fine

Takes a while to charge bout 2 mins
The norm will be to be on constant charge to save time

Nige Are you using regulators on the DAC board or how are you keeping the voltage steady? From what I can understand, you are not concurrently charging supercaps while playing DAC, are you? Have you found the sound better when not concurrently charging? We're using the amp power supply system Nothi...
