[Heathkit] DX-40 Questions

[Curt]

Yes, 4 ma is a bit too much for the 6146.   I peaked mine too just as the 
manual says after my DX-40 arrived and destroyed a 6146 after running it 
that way for awhile.  It had been too long since owning a rig with a 6146 in 
it.  About 2ma would be fine, 3 ma would be maximum.  Just back off on the 
drive to 2 ma and all will be fine, doesn't need to be peaked.

Antique Electronic Supply sells the 6DE7 for $3.80.  I've had good luck with 
tubes from them.

Who cares what the rig looks like, the op on the other end of the QSO will 
never see it unless you send a picture.  You'll have as much fun as with the 
first girlfriend too.
