Magnifique amplificateur de puissance à tubes Audio Research D-70 en parfait état esthétique et de fonctionnement. Cet appareil a été intégralement révisé par notre équipe de techniciens spécialisés, tubes neufs.

Sortie en 1983, L’Audio Research D-70 est un amplificateur à tubes dans la lignée des meilleures productions de la prestigieuse marque américaine, au niveau esthétique rien de changer avec la traditionnelle façade grise en aluminium rackable 19 pouces avec des poignées assorties, des sérigraphies noires et des témoins LED de mise sous tension.

Mais l’intérêt d’Audio Research se situe à l’intérieur de l’appareil avec 3 transformateurs surdimensionnés, celui du centre pour l’alimentation principale et les deux autres pour l’adaptation d’impédance afin de permettre à ce bloc de puissance d’avoir un rendement identique quel que soit l’impédance des enceintes.

Équipé de 4 tubes 6550 pour la partie puissance, d’un 5 ème tube 6550 pour la régularisation écran, 7 tubes 6DJ8, 1 tube 12AX7, le tout monté dans une configuration en push-pull travaillant en classe AB dans un circuit étudié pour fonctionner en toute sécurité quel que soit les variations de tensions, avec une version améliorée des circuits d’amplifications brevetés Audio Research à couplage croisé.

Le D-70 développe une puissance confortable de 60 watts par canal sous 8 Ohms, ainsi doté cet amplificateur est à même driver beaucoup d’enceintes du marché avec une belle aisance mais il faudra impérativement lui associer un préamplificateur de qualité pour en tirer toute la quintessence sonore.

Après un temps de chauffe d’une trentaine de minutes, cet amplificateur délivre une écoute très détaillée, ultra fluide, avec une sensation de douceur exceptionnelle, un des meilleurs blocs de puissance de la célèbre marque américaine Audio Research, un véritable bijou sonore.

Accouplé au magnifique Audio Research SP6 B l’écoute est enivrante, pas facile d’écouter un autre combo après cet ensemble !

Great dog balls at a great price
Size: Medium
The balls are a favorite for my dog. I could have done without the hole through the middle because I don't do treats in balls anyway. My dog loves balls for their own merit. I needed replacement balls for my Nerf Dog Ball launcher. It seems the originals have disappeared from the market. I took a chance because the price is right and this Chuck-it ball works very well so we're liking this ball a lot. So far my Dachsund, who can destroy a tennis ball (the kind they are selling as Nerf Dog replacements) in 3 minutes has not done any damage to this one so that's a win. I recommend this as a much better ball than the fuzzy tennis balls. I like the colors too since many dog toys are green (which gets lost in the lawn, etc.) or red (even though dogs have red/green color blindness. Blue and orange are good and pretty easy to find. I liked these well enough that this set was my second purchase so I will have spares in case the others are lost.

My Baby loves his new baby!
Size: Medium, Size: Medium
Finally! A ball my 107 lb. pitty/pointer mix can’t destroy. He has torn up every single “indestructible” toy in a day or so until now. He peels fabric and fur off non-rubber toys. He is a 4-legged shredder. I’ve added pictures of him for a size reference of my dog versus this product. I know I had wanted that when shopping for this item. This ball is now his beloved “baby.” He goes absolutely insane looking for it, chewing it, chasing it, and even sleeping with it. He won’t rest unless he knows exactly where it is. It is his only toy, and he is good with that. After getting this home, I tried giving him other choices, but he won’t touch them. I was worried that he would rip it apart by putting his teeth in the holes, but so far, not a scratch. It is soft enough to collapse just enough to keep it from cracking when his jaws crush it but not so soft that he can rip it to sheds. The holes are large enough to prevent a suction or vacuum effect on his tongue or mouth. For his size jaws, it is a perfect fit. Other dogs might have problems with suction or be able to get their teeth in those holes and rip it apart. Who knows? The older version of the Chuckit squeaky ball was his favorite for the year and a half he had it, but the way they make them now, he peels off the orange triangle in hours flat, the squeaker falls out (choking hazard), and then he rips it apart. I’m going to stock up on these. I can’t imagine how crazy he will be if they ever stop production or change the materials.

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.
