Dear Spinlanders,
Our 13C signal has degraded considerably since we bought our Inova in 2004. We are now calibrated at 20 us and 63dB for our 90 degree pulse (on non-lossy samples). We have narrowed the problem to the pre-amplifier or/and the amplifier. The amplifier has been repaired before. Has anyone seen this type of problem and can suggest a repair or replacement?
Happy Holidays,
Martha
