Hi everyone, first post here...This is a question for Revox PR99 MKIII users, although it's concerning a situation that probably applies to other tape machines out there. Basically I've been wondering if there is not an error in the REVOX PR99 MKIII manual, or at least the version I own.On the face of the machine, in the center below the tape heads, are the two 'Level' potentiometers, with 'Input Ch1' and 'Input Ch2' printed either side of the 'Uncal' button. These are listed as parts # 38 in the manual.On the base of the machine, below the removable panel that reveals all the calibration pots, are the two screws to adjust the input level, named 'Input level CH1 & CH2', at the center of the panel.In the very first section of the calibration procedure, we read:1. Remove the cover protecting the calibration controls (4 screws on the bottom) See picture below. (-> a picture of the calibration controls is printed underneath on this page)2. Connect AF millivoltmeter etc etc3. With AF generator, apply signal etc etc4. Switch on machine5. Release UNCAL button6. Set OUTPUT switch to INPUT7. Adjust monitor output to 0.775v with the corresponding INPUT LEVEL CONTROL (38)However, a few pages before, we read about the UNCAL switch that 'when this button is released, the line input is switched to the calibrated line level. When pressed down (position UNCAL), the input sensitivity can be adjusted with the INPUT LEVEL control (38).'So which is it? if you follow this procedure as it's described, there's no way you can adjust the input level to read the correct voltage from the monitor using the #38 controls, since they are inactive with the UNCAL button released.I'm somewhat new to all of this but... shouldn't the controls you need to adjust during this initial calibration sequence be the INPUT LEVEL CH1 & CH2 at the base of the machine?Thx for reading and for any suggestions!

I mean, in the meantime I just assumed I was right and went ahead with the procedure. The tape machine seems perfectly calibrated, inputs and outputs all coherent on monitoring, recording and playback.So either that was just plain luck, or there is indeed a tiny error/typo in the manual.Whatever I guess.
