I am currently using a Little Dot MK II as my pre. Is the FX-1 an upgrade?
The stock volume pot on the 6n3 is it's weak point. The FX's pot is far better and I counted 40 steps on it. They're small clicks but they're there.
Should have my power supply this weekend. Went with this one https://www.amazon.com/gp/product/B07GWCB534/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
Didn't want to go with a big Astron and the Pyramid's are kinda ugly. Hey looks matter.
Out of interest,is there a benefit of using that type of power unit over a wall wort type such as this?

I take on board the flexibility of the Nobsound unit but once the output voltage is set at 12VDC that should be it.
From a price point,the 3 pin is £15 or cheaper and the Nobsound is £80.
Also is there a maximum and minimum load current to supply the FX?
Im asking this as I don't want to buy cheap,but then have to buy twice.
Thanks. I can not solder, so that's out of the equation.
Now I am thinking of putting a passive preamp volume control nob between the Dilvpoetry and Emotiva SA-250 main amp (with 23.5k Ohm input impedance). I am thinking of basically cranking up the volume on Dilvpoetry tube preamp to eg. 12PM and then use the passive pre for actual volume control.
I'm looking at some reasonably priced FV3 units on the bay. I am confused about the impedance though, should I get 10k or 50k version? And should I go with ALPS RK27 or RK168 potentiometer?

Would not recommend this as being an unfavorable loading for the little pre.Thanks. I can not solder, so that's out of the equation.

Forgetting the words and riffing.What do you guys think about the video I posted page 42 ?
To me the preamp ad a little something in the tightness of bass frequencies. It's still very subtle.
The only bad thing to me is the hum I can percieve when there is no music (what would cause that ?)
Could be a ground loop, or just the added gain with the pre in the chain. I'm a minimalist as far as the signal chain goes, the least to get the best result and no more.To me it sounds like a transformer hum.
No hum when I remove the preamp from the chain.

I've rolled lots of replacements for the 6n3 but none that beats the WE 396A/2c51. I have them in my Sainsmart but they are expensive. A single at Tubestore goes for $80. A few years ago I bought a Dared MP-2a3 amp and was ready to send it back because the sound sucked. The seller told me to replace it's 4 Chinese 6n3's with WE 396A's and when I did it totally transformed the Dared into a great sounding amp.
Better tubes can make a huge improvement but it's not always night and day like an upgraded power supply. With a better psu I think the FX is the better preamp.
While I'm crazy about the the FX preamp and the DACT passive preamp I would only use them in separate systems. They both control the volume but in different ways. A simple switch box provides multiple sources for the single input FX and it does not degrade the signal. The DACT passive preamp OTOH comes with 4 source inputs. The FX with it's extra gain is ideal paired with the Miniwatt while the DACT passive sounds best with the single ended EL84.
