Philips Heerlen Holland production !

This is a ECC82 produced by Philips in1965 in Heerlen Holland (version Gf8). The tube bears the Philips Miniwatt print. The tube has a ring getter on ‘copper’ post and ribbed grey plates, see pictures. Tube with balanced systems; see test results.


The Heerlen ECC82 double triode’s most distinctive sonic feature, like that of many Heerlen double triodes, is its transparent, natural and sparkling midrange presentation, with a light touch of warmth illuminating your music. The sound image is spacious and deep, structured. The bass is deep but well controlled. I refer to the many threads on the web for more information. Excellent preamp valve and because of the low noise level, very suitable in phono stages.

Note: if your system is “bright sounding’ or to “bright/harsh” already, this tube is not a first choice. British made ECC82 tubes or Telefunken are to be considered in that situation.
