[Elecraft] Compare: K3 to Collins S-line receiver

[Joseph Trombino, Jr]

Howdy Gang.

I recently sold my S-Line that had a 75S3C receiver in it and I’ve owned two K3’s and now a KX3 and KX2.

I gotta admit that the tube audio was much more pleasant to listen to as compared to the solid state rigs.

Can’t exactly say what the differences are but the tube audio sounded much “fuller and rounder” that the solid state gear.

Don’t know if that poor description helps, but there it is.
