You may want to verify whether Elecraft specifies Thermal Material where the transistors attach.
My K3 and K3s both do. Haven’t disassembled my KX2. 73, Jim AB4AC Jim Finan [email protected] ________________________________ From: [email protected] <[email protected]> on behalf of Jim Brown <[email protected]> Sent: Tuesday, April 13, 2021 12:48:11 PM To: [email protected] <[email protected]> Subject: Re: [Elecraft] Elecraft Digest, Vol 204, Issue 6 On 4/13/2021 8:36 AM, Tommy Judson via Elecraft wrote: > Bought a KX-2 off the internet and have found that it is missing several of > the screws that held the end plates on.

Sounds like the seller was a sucker for aftermarket stuff. Elecraft products are well designed. The screws are all standard English units. Most of are 4-40, smaller ones are 2-56. I've NEVER thrown away screws -- I probably have close to a thousand, sorted into plastic drawers by size. Ditto for lots of other mechanical and electronic parts. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fmailman.qth.net%2Fmailman%2Flistinfo%2Felecraft&data=04%7C01%7C%7C241749b7db05448efa1d08d8fe9c224c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637539293821764867%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=FulrIvYY1%2FUYYuLfAXcLPXd3y9oDG99fodlIRZEjbx8%3D&reserved=0 Help: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fmailman.qth.net%2Fmmfaq.htm&data=04%7C01%7C%7C241749b7db05448efa1d08d8fe9c224c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637539293821774863%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=s99%2F642toAg78zPduxdio%2FrVpfYiBQb%2B3cyODIfv3hU%3D&reserved=0 Post: mailto:[email protected] This list hosted by: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.qsl.net%2F&data=04%7C01%7C%7C241749b7db05448efa1d08d8fe9c224c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637539293821774863%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=wn1I%2FdSdXotQxTPzP%2BwHjebE%2BJW9qE0z8Wc9laYXuDY%3D&reserved=0 Please help support this email list: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.qsl.net%2Fdonate.html&data=04%7C01%7C%7C241749b7db05448efa1d08d8fe9c224c%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637539293821774863%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=DppDFKHbJTPHoVOOsggBBE1L3lwlY%2Bv4HCpnbckD%2Bug%3D&reserved=0 Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
