Re: Duncan Designed P-90 specs
When taking a DC reading from a p'up, please note the temperature, as the nominal is taken at 20°C, and there's a difference of roughly 1% every 2.5°C.
To give an example: my magical 1995 '59n J measures 7.18K at 20°C (the REAL nominal reading), 7.33K at 25°C and/or 7.47K at 30°C.
Without this info, you could say that's either a SethN, A PGn or a '59n, all depending on temperature alone.
HTH,
