Test spectacular at 78 + 79 over 47 on a TV-7.  I almost don't want to sell these 1930's gem's!

 

Raytheon Type 45

  • Black base with gold “RAYTHEON – MADE IN U.S.A.”
  • Clear ST envelope
  • Octagonal “45” type marking etched on the glass
  • Large rectangular black plates with side rails

These are true original 45s, not later substitutes, not rebrands.


Era (this is important)

Everything points to early 1930s production:

  • Plate style (large, flat black plates with defined edges)
  • Copper-colored support hardware
  • Old-style mica shape and spacing
  • Gold base lettering (Raytheon used this earlier than most)

This is pre-war, pre-miniaturization American tube craftsmanship—when the 45 was still a mainstream audio output tube, not a cult object.

Construction details (why these matter)

Plates

  • Large black plates lower internal stress
  • Excellent heat distribution
  • Very stable bias behavior

This is the kind of plate geometry people chase for tone density and harmonic purity.

Matching & pairing

Visually:

  • Same plate tooling
  • Same envelope height
  • Same base finish and font
  • Same internal layout

This is almost certainly:

  • Same production era
  • Possibly same batch or very close

 

Sonic character (why people love Raytheon 45s)

Expect:

  • Incredible midrange purity
  • Open, unforced presentation
  • Fast, articulate bass (for a 45)
  • A very “present” soundstage—voices feel in the room

Compared to other 45s:

  • More neutral and open than RCA globes
  • Less romantic, more truthful

Raytheon 45s are often described as:

“The thinking person’s 45”

They don’t sugarcoat—but they don’t fatigue either.


Value & desirability

The 45 is already a top-tier DHT, and original Raytheons are:

  • Less common than RCA
  • Very respected sonically
  • Increasingly scarce in matched pairs
  • They’re absolutely reference-grade
  • Not hype tubes—serious listening tubes


Bottom line

This pair is:

Authentic early Raytheon Type 45
Pre-war construction
Excellent plate geometry
Visually well matched
Sonically refined and honest

These are the kind of tubes that define a system, not decorate one.

This is real early American DHT magic.
