Corby, AT what point would be approp to call symmetricom and complain about defective tube?I still have 2 years on the 5 yr warranty left, but how do u explain this (defect),,(I assume it will just keep rising and eventually ruin the tube within a few yrs?)last I checked they wanted about 28k for a new tube.
the unit with high perf tube has 5 yr warr from date of manuf. and cost 59k new. ---------------------- Original Message: --------------------- From: Corby Dawson <[EMAIL PROTECTED]> To: [email protected] Subject: [time-nuts] Cesium tube ion pumps Date: Wed, 3 Dec 2008 22:11:16 +0000 > David, > > The long storage is not the cause.
