Remote volume control for your Sansui

Strictly from a functionality perspective, it should work.
Inserted between source and amp or in the processor loop of the amp itself.
Having it in circuit means keeping the amp volume at the "max" desired level (not necessary max volume pot position) and then volume will change between "0" and that volume setting/level.
But....there are some ifs and buts:
1 - there are no technical details and/or specs.....like max input/output voltages, THD, impedances, etc
2 - final sound will depend on the device itself, the PSU feeding the device and the cables looping it. How much to gain or lose....impossible to say
Maybe a better alternative would be a good pre-amp having remote control for the volume and/or inputs.

Oh that is even better, and "on brand". Even found technical specs in the AK Database. Edit: I now have one on the way! Cool piece. Thanks for lead on that.

I doubt it is sonically transparent enough for demanding listeners (similar concept Sansui RS-100 is also not). The best solution is a passive preamp (just a pot, motorized for remote control, with a mute relay). Creek used to make such a device, called OBH-10. Sonically totally transparent. Hard to find these days (or. anything like it), which is a shame, very practical and usefull.
I wondered. RS-100 .15% THD through a .003% THD amp and maybe other signal influences, might be something there that is audible. I am a picky listener. I definitely want to try an RS-100 though - considering it's familial lineage. No data on the Newark product.
You resolved my concerns with using a preamp with that passive option. I'll keep and eye out for one of those. Nothing currently out there. Plenty of their head phone amps though.

I tried Creek OBH-21, not the same, active circuitry gives it a somewhat bright sonic signature, plus the noise if used in lower gain positions of its volume control.
Love the looks of that 80's gear! Nostalgic.
Not yet! I need to track one down still. And I do really like the sound of those machines. Punching so far above their weight in the SQ department. Best bargain in Sui-Fi (for reasonable level near field listening). "Advanced" Diamond Differential FTW.
Right now I am imagining my soon to be system, from the listening chair -
INPUT - CD-a607
POWER - Yet to be revealed new-to-me JDM Alpha
L/R - Magnepan's
LOW - Rythmik servo subwoofer (fed by headphone jack thanks to that pro tip from @CrSens)
All remote controlled from the ease of a nice bean bag chair. And the house cat will be there too. This winter is going to be great!

Just found the technical sheet on the Newark product. The Sansui from the 80's beats it in THD! But better SNR with the Newark. Not sure how to compare the other specs. Just might need to run an A/B test to compare. The Newark wins in simplicity though.

Well, that 1.65V max input level can prove to be a problem with nowadays devices (like cdplayers and DAC's) which generally have 2V or even 2.5V output level. It really depends how the circuit is done - that will inevitably impose some limits. Given the size of Newark device, I bet on something like a dual op-amp inside, configured in non-inverting mode and acting as a buffer.
Good information. That passive Creek device suggested above sounds ideal.

There is a jungle of inexpensive passive devices from China, but most lack remote, and those with remote lack mute relay. I don't understand why no company is offering something like the simple and effective Creek.
Very likely so, indeed.
I can tell you from my recent experience that making a really good sounding buffer is not quite a trivial task. Especially with a high input impedance, like it was (and is) in my case.

I was actually thinking the max output line level of 2v might be a problem with older amps that have trouble with anything above150mv.

I use my DA-607i as pre amplifier. It has two line inputs and variable output.
I use another preamplifier for phono stage through tape out. And at the moment I am using it as DAC so even have a line input to spare.
With a Sansui alpha integrated amplifier connect it to power amp direct, volume on -0dB.

Here is some real life testing of the Multicomp (Newark) product
