Hi Folks,
A couple KPA500 assembly hang-ups I have run into so far. KPA500 is S/N 550. I am experiencing the problem where PA heatsink holes are not deep enough, so the 5/16 screw length called for (to mount the Z bracket) bottoms out and the bracket remains loose. I see in the archives where some use 3/16 length, so I'll do that. The other problem I ran into was with the 40 pin I/O cable. Mine was not keyed properly to fit the board connector. One of the ribbon cable connector pins is blocked off so that the connector cannot be mated in either direction. I am proceeding by using a spare hard drive cable I had, but it has an extra connector along the length of the cable; I'm assuming this won't cause me any trouble farther along in the amp assembly. --Ed G-- ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
The 40 pin cabling being plugged wrong raises some flags. You might
want to contact support or call when they open. You can usually remove the pin blockers with a small screwdriver or pliers Mike W0MU J6M CQ WW DX CW Contest 2011 J6/W0MU November 21 - December 1 2011 W0MU-1 CC Cluster w0mu.net On 11/18/2011 2:44 AM, Ed G wrote: > Hi Folks, > A couple KPA500 assembly hang-ups I have run into so far.
