Hello, I am an electronics newbie and I have been putting together an EZ1073 preamplifier and eq. I have everything cased up and my voltage measurements are 23.95 for 24 volts and I biased across r26 to 130mV. But my 48v measurement was 48.5. Then I plugged it in just know and I'm only receiving 49.2 volts. Every time I try to adjust the trim pot, it goes down very little and only to 49.` So I don't know if this is fine or I need to replace something? Anyway, thanks for reading my post.
