Time goes by, and I almost completely discontinued my life-long activity supporting Varian NMR (and EPR!) spectrometers.
If you look for support on Varian/Agilent Spectrometers contact:
Mr. Luigi Mattavelli firstname.lastname@example.org
Dr. Bert Heise http://www.spin-doc.net/
Both guys are ex-Agilent technical support people and can deliver a top-quality service
For some technical hints and suggestions, look at the “Basic Troubleshooting” page on this website http://www.vpnmr.it/?page_id=137
If you think I can be of any help, feel free to contact me
