Peppennino,
Nice! I like that tray you have with the record player emblem on it. Where did you get it from?

Can anyone tell me how to add a pair of volume controls to my Aleph J please? The exact wiring?
Absolute easiest way? Product like this.

Assumes you have an already-built amplifier and looking to control output volume in the easiest way possible. No drilling, soldering. Just plug and go.
If you’re still building, there are other avenues. Which state of construction are you in?

Thankfully the Aleph J has a very high input impedance, as such it is compatible with passive preamps. In addition to Chris’ recommendation, there are some folks who like the Nobsound preamp and it has XLR outputs. No experience with it though: https://www.amazon.com/Nobsound-Ful...t=&hvlocphy=9010256&hvtargid=pla-496587361838

Thanks guys but I am actually looking at fitting a pair of volume pots on the front of each of my Aleph J amps .
One of these amps is built and I've been using it for a couple of years. The other is almost ready to put the large pieces into a box.
Both of these units are destined for my house and will be hooked up to the Biamp crossover.
At the moment I have the completed Aleph powering the high frequencies with only the digital input to control that volume.
The lows are going through a hybrid Monoprice amp which has it's own valve preamp so I can use this to achieve the best balance.
But once the Aleph amps go to the house I will also be using a turntable so there will need to be volume controls on both amps at that stage.
Thus I would like to know how difficult it is to fit volume pots directly onto each amp please?
That is the most simple in terms of boxes and wires as long as it's practical.
I just don't know what else is required apart from a pair of pots, or what value those should be.
I would much prefer not to add another two boxes to the system as there's already enough with the turntable preamp and the signal router and the crossover and two amps, a turntable and a raspberrypi with a screen and a few hard drives.
I made an unsuccessful attempt at building Wayne's burning amp as a preamp and probably will not complete that one and have been told more than once emphatically that the Aleph requires no preamp which I believe as it sounds superb.
OK? Just a simple volume circuit please guys.

This should be very easy and they would go inline between the connectors to board +ve input lines with a ground connection but I'll leave the exact wiring to someone else (though most of the pots instruction sheets themselves will tell you how to wire it up).
My advice is to use a stepped attenuator instead of an normal potentiometer. I have tried both, my potentiometer though high quality (a motorised TKD Potentiometer from Hificollective, so not a fake ebay pot) is not as good as the stepped attenuator and there is so much a difference in sound. Both are good, but a and b-ing the stepped attenuator has far better sound.
For reference, I have these:
The TDK pot:
TKD CP-2511, 2CP-2511 & 4CP-2511 Series Potentiometers | Hifi Collective
The Stepped Attenuator:

That sounds like good advice. What value are you using for the overall attenuator? 100K?
I don't think I can afford those ones you list. There are Dale filled attenuators on Ebay for a fraction of that price. And the boxes previously recommended were only $50 each. That's my budget anyway.
So maybe just fit a 100K pot in line and see what happens?

Yes, I have 100K, though it was actually originally bought to match a tube amp I built but reading something that Nelson said a while ago they should also be OK for the Apleph J (maybe someone can correct me if I interpreted wrong). In any case, I use this 100k attenuator myself and it works great with the Apleph J.
If they are genuine Dales, then the ebay ones should be good. My personal opinion is that even a lower quality attenuator is better than most pots, especially if shunts or the more expensive ladder types (mine is a shunt).
OK so I got a pair of these which are dual attenuators.

Looks good, assuming this chinese attenuator is using genuine Dale resistors.
This is a series type attenuator, and as you turn the volume down, more and more of the resistors are inlined in series, rather than swapping increasingly resistive resistors in as in the ladder and shunt types. This may result in slightly more noise floor level as the volume is reduced, but doubt that this would be audible at listening volumes and distances.
Stepped Attenuator
If you can drive 10K. I have used this attenuator with great success in my DCG3 preamp. Stepped Attenuator for passive preamp or amps

My favorite Monk!,
Indeed, the Korg B1 will make any amp sound “fuller” given the 2nd harmonic slant of the design! Depending on how the Aleph J sounds in your system you may/may not like the Korg B1 addition...auditions recommended...such is the spirit of diy. I would expect Waynes BA2018 to be more neutral which is why I am pairing it with the MOFO.
Thanks for sharing your impressions.
What’s the rest of your system?
Best,
Anand.
PsVoice: I’ve been using Tidal...just installed a Bluesound node 2i...trying different DAC’s. Rotating various speakers...I have a small listening room so no need for big power. Every devise/speaker changes sound. I’ve been searching my whole life for the perfect setup....still searching. 😀
I tried one (NuTube) with Klipsch Heresy IIs and the AJ and didn’t care for it as much as other options. Definitely audition if you can with as much of your gear as possible if able!
