Well, the unit works well, but it acts quite differently compared to my Hairball Audio Rev. A.Probably not...
But why are you measuring temperature? does the unit not works or has any problem?
I sent a 1kHz / 0db (0.775ACV) from my DAW to each compressor.How are you measuring the gain of each unit ?
Therefore all of what I said in my previous post are variables that might apply. I have a pair of MC77 that I made but I can't check how hot Q6 gets for you because they in France at the moment & I'm in the U.K. Q6 will get quite hot because it's class A, but you may have an issue, which if you do will likely be in that area, check the resistor values round Q6 & the output transformer wiring. I have a pair of MC77 that I made but I can't check how hot Q6 gets for you because they are at a house I own in France at the moment. I have attached a pdf from the hairball/mnats rev D build documents. It has test voltages on it which should be pretty close to what you get for the MC77. I don't know if the prts numbers are the same, but you should be able to figure it it. If you voltages are within 10% then it's likley operating normally.I sent a 1kHz / 0db (0.775ACV) from my DAW to each compressor.
With the output pot at mid position, attack pot fully CCW (off) and release pot fully CW, with meter on +4 I set the input knob on each unit so the meter will show 0VU (on both units).
I monitored the outputs on the DAW that show -19DBFS.
To achieve the same output I needed to raise the input knob of the MC77 much higher compared to the input knob of the REV.A.
