[Elecraft] XV432, Q1...

2006-04-22 Thread Gerhard Schwanz

Hi List,

I soldered faster than I read. So Q1 is now installed in a common fashion 
without teflon spacer. Leads are clipped. What am I going to do now?


If the teflon is just for spacing I would remove the Q, prolong the leads 
and install it without the teflon but spaced (I think the teflon won't fit 
then). Will this work or does the teflon some other magic?


If the teflon does some other magic I think I have to order a new Q1...

Have a nice weekend

Gerhard

Sorry to hear that Gerhard. I haven't tried it with the transistor installed
against the board but, as I understand it, the leads are required for
feedback for reliable operation. The Teflon spacer is a convenient way to
set the length correctly. It should work if you splice on longer leads as
long as they don't short out against each other. The other builders that
I've heard of doing that replaced the transistor. 

You are NOT the first to install Q1 without reading the step. Did you get
the Errata sheet that asked you to add this note ahead of that step?

NOTE: Read the following step completely and refer to Figure 23 before
installing Q1. Q1 is installed differently from other transistors in this
kit.

That should have started going out with the kits early this month (April) in
response to a couple of others who did the same thing.  

Is there anything else we could do differently to warn builders to read
before building?
