I have one for sale with top notch bendix and jj tubes. £350

FWIW the Russian Caps sounded pretty dire, very dark and somewhat compressed. Swapped them out for a pair of Aurica, same spec as stock, and they have promise. A little more snap than the stock but not as open and airy, I'll give them some more time and report back if something blooms.

Hi guys - I have some Russian K75-24 caps 2.2uf and 400v left over from a previous DIY venture. Would they be viable candidates to use at output? The voltage rating is much higher, but from reading some previous posts on this thread there seems to be some consensus that this is not a problem...

Your replacements have the PIN numbers printed on top, this is your savior. Look up the specs of the opamp your replacing and you will see the position of its pins in relation to the orientation of the opamp. Your original will have the generic scoop out of one end. Hope that helps.

Any chance your generosity would extend over the pond? I have the bendix, a 1964 production, so could provide a direct comparison. Happy to cover postage cost :0

I know this has been asked before but I remain a little confused after reading replies. I have the option of digital out "coax spdif" from my asus motherboard and the option of the stx digital out "coax spdif". Is there an appreciable difference/improvement by using the sound card? And to what...

I went for the nano digi after hearing to many reports of high noise floor and reduced SQ with the standard minidsp. After all, the analouge signal from your swish DAC is digitized processed and then converted to analouge again through tiny little DACs. Can't be a winning situation for high end...

What did you find changed with the resistors around the tube and the vishay diodes? That's my first mod planned. Thanks - happy crimbo

Im going to opt for resistor changes, rectifier upgrade and spend the change on output caps. Thanks guys.   Another question, as I have some experts out there.   The Coax spdif is SO much better than the USB input. Is this a common finding or have I missed some settings with my PC? And whats...

On the subject of power supply. Nobody here seems to have attempted a shunt regulator to ensure a super clean DC, is there a reason why not? The Salas shunt regs are legend and can be populated with little cost. Maybe I'll try that as well as the other recommended mods, and report back.

I have a Havana DAC which I bought for £320 and it came with a 1954 Bendix 6385. I didn't like it!!! What? So I got a JJ 6386 which seemed like a superb £100 spend at the time, but I kept reading people rave about the Bendix, so I gave it a longer audition. Given time to warm up - it has knocked...
