Wow- a remote system for this attenuator and I'm SOLD! You guys at twisted pair are making some excellent kits!
Any toughts on implementing a balance control? I guess I could run 2 attenuators with 2 remotes!

Any update on the new remote controlled volume and source controller? Website looks like you are sold out of a lot of stuff, maybe waiting on new designs to come in?
Thanks

Precisely 🙂
We have one round of DAC related stuff coming very soon, shortly after that you will see some new things related to a "uber controller" with display etc which we are currently perfecting.
Actually, yes. talked to him long ago about buying the whole reel. We use the through hole version however, and a slightly different footprint (even pin spacing).
Thought about buying them for an eventual redesign, but alas, I have enough extra inventory hanging around.

Can I hang this off a +- 15 V DC supply and bypass the onboard AC-DC portion of the circuit, or will it need it's own supply? My +-15 V supply can handle the current requirements posted on your website.
Thanks!

You could, or you could run the +15V into the normal AC input. The repeat rectification would be basically bypassed (one route through the diodes). One guy is using it as a balanced volume control in his car, powering it with 12VDC.

excellent. Great! So, I can give the LM7805 30 V DC (the datasheet says maximum of 35 V DC for V_in) from the +- 15 V DC supply?
Do you have any ideas when more kits will be available, and maybe what new features will be added?
Thanks!

No I would not do that at all, just use one of the 15V voltages and GND. If you use 30V the HS of the controller will get very very hot.

Its it coming along nicely. Expect to see something in the next few weeks. 🙂
if only I could do this full time!
Cheers!

Cool!
I am still soldering the KITs I ordered.
So it would be cool to have a controller with dispplay to finish a preamp.

cool! success! one last question. I'm going to order another kit when they get back in stock. Will the new kits include Phoenix or the Vishay-Dale RN55D 1/8W resistors? Will the same resistor values be used for attenuation?
Remote Control Suggestions
Hi Russ & Brian,
May I suggest the following for the Remote Control feature for the JT?
1) Have connections for panel push-button switches to control the functions that are on the remote unit. I suggest the following functions: Volume UP, Volume DOWN, MUTE, and RESET. RESET immediately sets the attentuator to full attenuation (-63.5db), whereas MUTE of course only disables the OUTPUT while engaged.
2) Suggest a front panel LED that blinks every say 0.5 seconds when the MUTE is engaged.
That's about it!
Please keep us informed on your progress!!!

PLED Display
Russ & Brian,
If you don't mind me asking, where did you get that PLED display for the JT remote? I hope to play around with one. Thanks!

Here is a few pics of my balanced preamp setup, using both the JT and the Darwin . Both are working very smoothly. Much better than the usual 4 deck Elma's and whatever I have tried out. The attenuation curve is very nice. One can ofcourse use most any gainstage with them, here I am using the TX-drivers, which keeps impressing with the sound. I am a bit surprised about them 🙂
Here is first the inside:

As I am using both single-ended and balanced input the -IN is shorted to GND at the input of the Darwin, when using SE, which is a convenient place to do it. -IN is automatically shorted to GND when selecting one of the SE inputs. Simply solder a small wire at the connector like on the pic.
