MU524 Vari-Mu Tube Compressor / Stereo Right Kit

« on: August 05, 2025, 01:00:54 AM »

I just received my MU524 Stereo right kit and it appears that the part U6 is the exact same as my Left/Mono kit. Is it possible to get the correct version of the U6 as what I received looks exactly the same down to the number values on the all the parts on the U6 on my Left/Mono Kit?

Yes the value of TR4 is marked 502, and the R32 Value is correct.
Also I really missed the negative sign on my DMM, it was placed directly below the DC symbol and I didn't notice till I came back to it

the max value was something like -7.32

I just finished setting it up, Thanks for your response. I suppose I just needed to step away for a bit. I just ran music through it and it seems to respond like a compressor. I have not listened to it yet as I have not put it in the correct spot near enough to an input. I will come back if it does not sound correct (hopefully in the next few days as I am 40 yrs old and started back to college this summer and it's finals week).

Again thank you, much appreciation

I cannot get my DMM to show -2 when adjusting the TR4 VREF. It goes to zero before the Trim pot starts clicking to let me know I've reached max adjustment. Am I missing something? 

Do I need to adjust the output potentiometer back to zero (instructions does not mention to do this)?

Also do I need to pick a sidechain setup step to go with(i.e. -3db @ -2v, or -6db @ -3.6v)?
