I was hoping to run this question by Yves or any one who may have experience with this module. I recently built this module and am experiencing an unexpected low output. My input signal is +/- 5 V so I adjusted R21 to be 1.2k. This knocks the sine wave down to +/- 60 mV at base of Q1. I feel that this is correct. The circuit seems to work fine in every way but to get the output boosted back up to 10Vpp I had to increase the output gain more than what Yves suggests. I ended up using a 82k for R18. I'm only concerned because my signal is less than half the strength of what the website suggests it should be if the design is to output a 20Vpp signal.
Any thoughts are welcomed and appreciated.
