They don't make any mono stepped pots, but at those prices, just buy two and only use one section of each.
I’ve been reading info about TDK 2CP-2511/4CP-2511, there they states “Please take care not to use for setting resistance value, as, if so, we are afraid that a trouble may happen.” Therefore the question. Otherwise no problem, got it!
Hi
I have a few questions:
Where do i get the Solinec nsl 32sr2 ?
Are the Advanced Photonix nsl 32sr2 from DigiKey just as good ?
How do i make sure, that the ones i get, are all grade A ?
Hope that someone will answer..
Thanks

If you want the ones that are going to give you a closer match with less left overs (waist), you need to hunt down the NSL32SR2S (the 'S" on the end stands for selected) you still have to mach them up, they cost more but you 'll need far less of them to get the matched sets, and you'll get a lower minimum volume from the "S" ones as they have a lower min impedance.

How many matched one’s did you got from this 30? Is your Lightspeed attenuator working?
I used to get 5-10% dump rate out of 100 pieces NSL32RS2S. The NSL32SR2 was more like 10-20% wastage, and they didn't go low enough in volume either.

What would be the effect of adding resistor, in series or parallel, on the output side of the LDR to resolve lowest volume?
From page 1, the mono config can handle balance.

You raise the output impedance even more than it is to do that, as it is, the Lightspeed Attenuator likes to see 33kohm or higher input impedance to the poweramp it sees.
Not a good thing for I/O impedance match into poweramp, like adding a resistor to the output of a poweramp. to lower the volume.

Same here… bought a set of matched LDR’s in 2011 or so. In 2012 I discovered the LDR’s weren’t matched… not sure if this was out of the box or happened later. By the way I completely forgot that I had already discovered this problem in 2012 already, even emailed Uriah about back then (no response).
Anyway after long hiatus I would now like to sort this out, so looking to replace the LDR’s. Is it me or have they become absurdly expensive? Looking at 3 euro’s a piece for the non-selected version, so probably need a fair number of them to find a matched quad (30? 50?)…
If anyone has matched quads available I’m all ears…

I bought a kit from him several years ago that I never built. Let me dig it out and I’ll post what I have
He never used the NSL32SR2S (sorted) just the NSL32SR2, (or NSL32SR3 which will never work as I intended them to), he was a copier and called it his own, bad grapes, yeah you bet ya!!!
Another one was this BS opamp he sold with this transistor (what is basically now a diode) in the voltage rails

Can't seem to find "S" grade in Europe... feels wrong to buy 25 NSL32SR2 (EUR 54 at Mouser) just to throw away 21...
Got that a little miscalculated.
Quote: Me (The NSL32SR2 was more like 10-20% wastage) From 25 pieces that's 2-4 pieces thrown away not 21)
