Well, if you ever get the opportunity....get a nice TR4C!
I have an SB303, 301 and an SB102. They are mint 'keepers', but they are
just light years away from the overall quality and performance of the TR4's

Yes. Good point.

I don't own Drake except for a 2B/2BQ that's been in storage for 35
years. Don't know a lot about them, never operated a TR.

Overall though, the SB-102 package, as part of the Heath SB system
which includes several amps, scopes, etc., was the premier 1960s/1970s
set up. The weakness of the SB's was the mechanical build quality
and the mechanical alignment.

Drake PTO vs. Heath LMO is an interesting comparison. My SB-102 is
not seen bench time yet but I've had an SB-303 (same solid state LMO
albeit without the tubes nearby) on a frequency counter for a week.
The drift measured in the few tens of Hz! This was in an un-
airconditioned room.
