Hi mikkel, I mount the kit relvol1 and it works fine, I have two small problems, the first, I hear in the loudspeaker the click on every step, and the second is that I can't totally mute it, is that normal?
Piero7,
You have the same kit as I. You are correct in that you hear the "Click" when you change the volume level................drives me crazy!
The mute is only intended to drop the volume to something like -53dB, so yes, you do hear it softly in the background when mute is engaged.
I wish I knew how to eliminate the "click" when changing the volume, otherwise I really really like the RelVol 1 kit. If you have any ideas on what to try to fix the "click" let me know please!
Ron
And now we are two waiting for a reply...
But also at volume zero I can't stop mute totally the system!! And that click is really get me crazy!
In all fairness, I have asked Mikkel about the clicking and he suggested changing out the relays.........sure would have been easier to offer silent relays for more $$$.
Just a thought Mikkel.
Mikkel has been helpful to me and I still like his kits, prices are good, he usually answers the posts and questions...........just may take him a couple of weeks.

Piero7,
Yes, I can reach Zero sound output. Mine is on my preamp and not an amplifier per say. As I recall, there are two ways to set up the board, one with zero dB increase and the other way with a small dB increase.
In other words, the module can be a zero gain or a small gain device.
I'm moving my house, so I have no idea where my paperwork is located, sorry.

Oh, mine too is mounted on a preamp, please, help me to reach zero sound output, just to have a problem less 😱
Piero 7,
OK, I'll look for the manual in my boxes today and try to help you with the settings.

Piero 7,
Please be patient, I WILL find it and get back to you, but it's gonna be a couple of days. Monday most likely.

Piero7,
Ok, I found the manual, Do you have the RElVol1 or RelVol1C board?
What is the value of your imput resistors? R28 & R29?
What is the input impedance of the linestage (preamp) after the attenuator board?
Changing the R28 &R29 values will change the total amount of attenuation.
I thought it was a jumper, but that was another board I had built.
I remembered wrong. Sorry.
I'm using an Aikido 6sn7 tube preamp with 100K impedance.
Don't forget that when this board turns on it doesn't start at the highest level of attenuation -63 but at -53, a midway point about 1/4volume.
I hope this helps, I can measure my resistors in R28 and R29 if needed.
I have to take my preamp apart to do it. Why I haven't done it yet. 🙂

Yo, mine is the RelVol1C, and I have for r28&r29 111K due my Aikido with E800CC is 1mega drid resistors
Nope, I get no volume zero even changing these two res and the grid resistors from 1M to 100K and adding 11K for r27&r28 🙁 Argh!!!

P7,
Good, mine's the RelVol 1 C version too, that will make it easier to help you.
I'm sorry, I must have misunderstood your problem.
Are you saying that you get 0 volume? No sound at all?
Or, your volume won't turn down all the way to 0dB?
We'll figure this out together!
Don't give up!

P7,
When you ordered your board from Mikkel, did you order the 10k or 100k resistor package?
Looking at my R27 & R28 I come up with 126M + 100K in series for each of the "Load Resistors".....? That doesn't sound right to me, but it's whats in there. Picture from my board. I don't remember exactly what I did to get those #s but I do know that I had to change them a few times to get the volume to adjust correctly. It has been a while since I built my Aikido.
What is the MU of you preamp? I thought mine was high at ~21MU.
Your tubes are E800CC right? Are they similar to the 12AU7? If so then the expected MU is ~ 17 -18MU.
Don't change the Grid stop resistors in the Aikido! Change the load resistors in the ReVol1C. Try a 100M resistor.
It doesn't sound right but that's what I ended up with.
