Hello to all in this group,
Thanks for being understanding during these trying times.? I have not yet returned to my office in Minnesota where the Red Devil resistors are so as you can see, I have not been able to fulfill my promise to you as I am still in Loveland, Colorado.??

I have orders in to get a Loveland cal on all of my 3458A DMMs which I was planning of have performed while in Loveland being that my office here is just 3 miles from the Keysight facility.? That does not look like it is going to happen so this will all have to wait until Keysight cal lab is back in business.? I have upgraded the CAL RAMs on my 3458A meters as well as some of the other parts related to the high stability OHMS and voltage reference internal to the meters.

The good news is that I have gone through my inventory here in Colorado and have found considerably more items than I remember having.? I have parts and boards and many case parts related to the following instruments and related I/O cards:
3421A, 3455A, 3456A, 3457A, 3458A, 3468A/B 3476B, 3478A, 3488A, 970 probe meter,? some oscilloscopes 54501, 54511 and spectrum analyzers? 3582, 3585, 8754A, 8753A? and all the I/O cards for the 3488A:? 444XX series(XX= 70, 71,72,73,77,78, 91,92?and I/O cars for the 3457A.??
I have a large supply of the Aromat relays(new unused) that I used in the design of the 4447X series of I/O cards for the 3488 should you need to replace any as well as other components used on the boards

The 3468 and 3478 meters and related axial leaded and ICs and custom hybrids I designed are also in my inventory and are in sufficient supply to fill anyone's needs. In fact, the SAFT and ETERNACELL 3.0v lithium back up battery for the cal RAM some were looking for earlier are here in Colorado.? I can make them available at a reasonable price of $2.00 each.? All of them measure 3.03v or better.

Thank you and I will notify group when I am back in Minnesota regarding the Red Devil resistors.
I can ship other parts from Colroado if needed.? I am scheduled to hit the road to Minnesota once I load up the truck with the inventory on the 28th of April.? Hard to believe I have been here almost 2 months when the initial plan was to be here 2 weeks.
