RCA 2A3 – Early Production, Black plate - Beautiful Matched Pair

Price is for the exact pair pictured

Super-mint pair of RCA 2A3 tubes.

TV-7 Test Results:

63/38

62/38

The CRC marking points to RCA’s military contract production, almost certainly:

• WWII era
• Built to naval/military reliability specs
• Tighter tolerances than civilian consumer tubes

Are they a matched pair?

Visually:

• Plate structure, mica shape, getter placement, and internal geometry look very closely matched
• Same general era and factory lineage

Sonic character (what people chase these for)

These RCA's are known for:

• Big, saturated midrange
• Natural tone density (voices sound human, not hi-fi)
• Slightly softer top end than modern mesh plates
• Incredible flow and ease—no edge, no glare

They’re not about “detail fireworks.”
They’re about music breathing.

On TV-7:

64/38 & 60/38 so these are very strong tubes.
