E80CC Pair Philips Miniwatt, Pinched waists, Physical Lab selection, D-strip, red tip 1956 (v16/v19)

Description

Nice pair E80CC twin triodes, Excellent condition, made by Philips in Heerlen, Netherlands

This is an very early WK5 version of the E80CC!  On both tubes the Physical Lab selection is etched and on both the week code 34F is etched.

The tubes are produced by Philips in the fifties (1956) in Heerlen, the Netherlands. Both are a red tip selection. The tubes have a D-foil getter on copper post, are reinforced and with long ribbed plates and pinched waists, see pictures.

These tubes are  highly regarded for Audio equipment due to the rigid construction, matched sections and good linearity. The sound is praise in many reviews on the web; realistic, holographic, robust lows and space.

Very healthy tubes with matching systems; see test results.

Sonics

This Philips E80CC considered to be superior to the later E80CC version and is highly regarded as a ECC82 replacement. I refer to the many threads on the web for more information. Excellent low noise and very smooth performer with substantial authority. 

Verdict of a buyer: The sound  is excellent – tight, nice sound stage, vivid, super balanced with authority.
