It's in the +/-20% range, which is usual tolerance for potentiometer
P1 is an input attenuator so I suppose the log curve is the more important for matching position.
P3 is sidechain time release, miss match will change accordingly the max time release, but in stereo the sc is summed after that so not a real issue, the time release will be the longer for both side.

thank @zamproject for your answer, I think I could start my build safely now

Hi there, just did the components check this morning on my 2 MU524 vari mu kits. Everything seems to be there, but I'm wondering something about P1,P2,P3.
They are 10K, 2K2 and 2M2 potentiometer. When I measure them I find :
P1: 8k17 and 8k85
P2: 2K3 and 2K3 (seems ok to me)
P3: 1M87 and 2M14

Is there any issue with P1 and P3 values, as solo unit, and as stereo bus comp?
I really don't know, just asking there to have some advices

Thank, and enjoy the sunny day

Most pots have 20% tolerance and those are all within that range.

Correction. I had made a mistake when building. I had the a transistor backwards. Now corrected. I'm not getting 3vac output during setup. More like 1vac.

@Forcemusicgroup
If you dont mind, can we continue this debugging topic in our dedicated forum or by emails?
I'd rather keep this topic for product announcements and general questions?
Thank you very much.

Have an AB528 arriving tomorrow () will post a pic once complete.

All buttoned up and sounds beefy and clear!
Great build guide, nice components and went together in about 5 hours of takin’ it slow.
Another would be nice!

By the way, the side cover should not stick out from the front panel, like in the picture. Is it just untightened?

 

[Toobme]

I will tighten that down, thanks. No reason for that!

 

[Toobme]

Ok, forgot to add the washers on the spacers. Perfect now!
Thanks, @JPK !

Haha, just noticed the LMW28F mark on the bottom right of the faceplate.
Nice touch!

Also, updating to say I’m loving this on vocal - very rich.
The impedance switch is useful here, almost like having a different mic, going back and forth.
Also, small point, but i’ve never liked a single LED meter more than this one; it’s reactive and does a good job of representing the signal. Turns red on overload (not sure level required).

Dialing the output knob down and cranking the chicken knob does as expected and gets the sound large and in charge, but still clean - hard to describe.
I’ve never used the Chandler, ir the original, but this pre will likely eat up another spot or two in my lunchbox.

Thanks again for a great kit - a real treat to put together and sounds fabulous!

You are the first to get the joke!
Thank you for the kind words.

Just to leave a little feedback here :

I recently built up a MP573 and its awesome!
Good Quality
Perfect instructions
Easy build Overall
Easy Setup

Just thank to this Greatness to humanity

Hello! Can anyone tell me if the EQP501 is stepped or not?
I love easy recall...
Thanks!

If you look at the photo of it on the first page you can see that frequencies are switched but level is not. You could figure out what kind of rotary switch would fit and use that instead. The pots for the levels are linear so the resistance per step would be easy to figure out.

Thanks!

We are working on making some demos.

Any news on audio fiIes for the Mu comp and the opto comp?

I have one and I will tell you it's a must have

Which one do you have? I want to build the Mu as gift for a friend, what an elegant little circuit.

 

[Forcemusicgroup]

I have the MU. Love it on vocals

Fantastic! It's for a young mixer and I figure it might be a good hardware starting point to stand in for the Unfairchild / Fearn that are so popular here in LA
