A full model change of the middle level vacuum tube output driver unit

STAX introduces a new vacuum tube output driver unit “SRM-500T”, the successor model of “SRM-006tS”. STAX custom-made low noise DUAL FET is installed on First Stage and the vacuum tube”6FQ7/6CG7″ is installed on Output Stage. STAX continued to use the traditional circuit design which is perfect for STAX vacuum tube driver and improved the power efficiency. Finally SRM-500T achieved the sound quality improvement.

In addition to the conventional power transformer for the high voltage circuit, the newly designed power transformer with the winding for the low voltage circuit is installed in SRM-500T. The low voltage winding enables to improve the power efficiency and achieve further power saving and better sound quality than the conventional vacuum tube output driver units such as SRM-006tS.

The new chassis which is more rigid than the conventional model is installed. The chassis has a hybrid structure using a lot of non-magnetic aluminum and further reduces the effect of the environmental noise factors such as vibrations. The inputs are RCA and XLR, the mutual exclusion inputs. The custom made concentric dual volume knob which is common to STAX products and RCA PARALLEL OUT functions are installed same as the conventional driver units. All electric components are strictly selected considering the environment. Also the sound quality and the performance is improved. The complete DC amplifier configuration that the signal circuit includes no coupling condensers is one of the biggest traditional features.

The clear and highly transparent sound, a feature of the vacuum tube circuit and the warm and wide sound texture is maintained and the thickness of the low-mid range is brushed up. This is the new choice for the combination with the advanced lambda series (SR-L300/SR-L500 MK2/SR-L700 MK2).

She chewed it up in less than 10 minutes. This is not for heavy chewers but dogs that like to actually play with their toys it would be great!!! I gave it a 3 because it worked for my other dog who likes to play🤘

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage. Is colorful and my become my puppy’s favorite.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
