Rare estate find. Philips Miniwatt ECC82 early 1960's made in Holland @ the famous 'Heerlen' factory. They all have the delta sign on the tube. Some with print, others not, but this is mentioned at tube level. Prices mentioned are for a matched pair of 2 tubes!
This tube is true part of the family. Produced in late 50s (this specific tubes is from 1959) to early 60s. Sound, although is not as musical as long plates, but it’s a pleasure to listen to it. One of the truly great 12AU7 tubes. The sound is transparent, romantic with good mixture of warmth and top register sparkle. Airy and relaxed – you just want to keep listening to it. What strikes the most about this tubes is how smooth it is and how good treble sounds. Amperex is a great example of what I’m talking about, but this tubes has outdone Amperex in treble department. HIGHLY RECOMMENDED.
There is no other tube that can create the magic of Telefunken. The magic comes primarily from airiness – it’s like a bit of reverberation after a note is played. So the purists would say it’s not precise and I would agree, but music is not about precision – it’s about enjoyment and the airiness adds to the enjoyment significantly by making soundstage much bigger. Highly Recommended.
