Hello. I've designed an high frequency amplifier using an NE592. It works properly with an exception, which is that gain adjustement is exactly the opposite that what is described in Application Note. Practically I've put a 100R trimmer pot between pins 2 & 7 (DIP-8). Accordingly to AN, gain must be maximum with minimum pot resistance, but practically my gain is maximum for max resistance, ie 100R. Can someone explain me that strange point. Thaks by advance.
