If all else fails.. Elecraft Repair & Alignment Service
Email us at email@example.com to send in comments and corrections and for technical support.
Also, the Elecraft email reflector is a great place to ask questions of other K2 builders.
Please send parts requests ONLY to firstname.lastname@example.org We may miss them if they are posted to the reflector or to our individual email addresses.
It is a good idea to inventory ALL of your K2 kit before you start building. That way we can send you any missing parts in advance of your actually needing them. We know how frustrating it can be to get to a step in the assembly and be short a part!
