Introducing the EAR Yoshino Phonobox Tube Phono Stage: A Testament to Timeless Audio Engineering

The EAR Yoshino Phonobox represents the pinnacle of audio craftsmanship, blending traditional engineering with modern innovation. Designed as the last masterpiece by the legendary Tim de Paravicini before his passing, this tube phono stage is a fitting tribute to his genius, combining simplicity with exceptional performance.

At its core, the Phonobox is distinguished by its straightforward, effective design that encapsulates the best of vacuum tube technology while minimizing the drawbacks often associated with vintage devices. Unlike conventional phono stages, it simplifies the input-matching process for Moving Coil cartridges by employing matching transformers, eliminating the need for complex active designs. This decision underscores a commitment to purity and quality, hallmarks of Tim’s design philosophy.

The selection of the 13D16 tube, a unique variant designed specifically for EAR Yoshino, exemplifies the Phonobox's bespoke nature. This choice reflects a dedication to achieving optimal performance without compromise, ensuring that the Phonobox delivers unparalleled audio fidelity as intended by its creator.

Construction-wise, the Phonobox is built to last, with a robust metal chassis, high-quality Alps Blue Velvet volume control, and substantial rubber feet. Its design is a study in functional elegance, eschewing unnecessary embellishments in favor of durability and reliability. The attention to detail is evident in every aspect, from the solid construction to the thoughtful selection of components that exceed the specifications of similarly priced competitors.

The Phonobox's audio performance is nothing short of remarkable. Its ability to handle both MM and MC cartridges with aplomb reveals an adaptable and versatile device. Listeners can expect a rich, detailed sound profile that breathes life into vinyl records. The unit's bass response is particularly noteworthy, offering depth and precision that elevate the listening experience. Moreover, its remarkably low noise floor in both MM and MC modes sets a new standard for tube phono stages, addressing one of the common criticisms of such devices.

But the EAR Yoshino Phonobox is more than just a piece of audio equipment; it's a bridge between the past and present. It embodies a nostalgic synergy with vinyl records, invoking the era when tubes were the backbone of audio reproduction. This phono stage is not just about listening to music; it's about experiencing it in a way that honours the rich history of audio technology.

For audiophiles seeking a phono stage that combines exceptional audio performance with historical reverence, the EAR Yoshino Phonobox Tube Phono Stage is an unrivalled choice. Its design philosophy, rooted in simplicity and quality, along with its sonic excellence, make it a must-have for those who value purity and depth in their music listening experience.

Top notch tire sealant!
Size: 20oz
Really good sealant that lives up to it's description. Very easy to use and definitely delivers. Have used it on several Lazer Z mowers and works as advertised! Definitely would recommend this one!

This stuff just works! Very impressed. If you have a slow leak, get this!
Size: 20oz
This is the second time I've bought this product. I bought one initially to test it out and I was very impressed! I had put some used tires on some used rims for my side by side and I had a couple of them leaking slowly from the side of the rim. I put this stuff in, following the directions and have no more leaks! It's been about a week with the first one, and zero loss in air pressure. I took my side by side out on the trails and thrashed around a bit, still no leaks! This stuff is legit! It comes with a valve removal tool and red valve stem covers to show you which tires you've added this too. Very easy to use, no issues whatsoever. Saves you money having to take your tires somewhere to have them look at them.

This stuff worked better than I thought it would
Size: 40oz
As my title says, this stuff worked better than I thought it would. In fact it worked so well today I will be ordering more. I say today because how can you tell if something like this is actually working... never getting a flat for years? In other words, if it fixes a flat before your eyes it works, otherwise you really don't know. See I had a lawn mower tractor that developed a real bad tire leak a couple of days ago. The way it happened was I cut a Russian Olive tree down, if you know what one of these trees are like, you already know why I got such a bad leak. These darn things have thorns that can get to be almost as big around as a pencil, and are just as sharp as a needle. Moreover, these spikes as I call them, can get to be 3" to 4" long. In short, if you run over one you will have a flat tire, period. That is unless you have this stuff inside the tire already. To make matters worse, if you run over a branch from this tree, you won't only get one or two thorns/spikes stuck in your tire, because as you drive the branch bends easily (only the spike are ridged), so before you know it you will end up with a half dozen of these spikes all the way around your tire, as if the whole tire has a new tread made up of a Russian Olive tree branch. Trust me on this, it will happen just like this. After pulling a half dozen 2" to 4" inch spikes out of the tire, I knew if I took it to a shop they would require me to put a tube in. With this inflation that isn't supposed to be an inflation going on, I'm sure it has made tire tubes today cost almost as much as the whole tire cost me just a couple of years ago. So I thought I'd put this product to a real test... I already have some in my John Deere 2305 tractor. Honestly, it shocked me how quick it worked. It worked so fast I didn't even need to add anymore air to the tire, because all the holes were shut. Pretty amazing stuff if you ask me! I followed the directions, they were easy to follow and the process was easy too. I removed the valve stem, put in 5 ounces of the solution, then put the valve stem back in, aired up the tire and it was instantly fixed... amazing, especially considering why the tire was flat... I should have taken a pic of the spikes. I did roll the tire around a bit, then mounted the tire back on the tractor and went right over and mowed my elderly neighbors lawn, so it got plenty of rotation time. That was about 4 hours ago and the tire is still rock hard. Like I said, I'm ordering more because after seeing this everything we have that runs slow will have this stuff in the tires! Oh, one other thing. The fix-it flat stuff in a spray can, DO NOT USE IT for applications like this! Because that stuff if left inside will actually glue your tire to the rim. Tires have been ruined trying to pry them away from the rim after putting in fix-a-flat, or whatever that crap is called. Sadly this "TireJect" is not recommended for high speed travel, it will through your tire out of balance. So use the fix-flat stuff in an emergency, carry one in your car just in case. Just make sure once you get the tire fixed wash the tire out real good before remounting it. I have never written such a long review in my life, but if you got through it I hope it helped. It's not often a product lives up to it's claims today, but this one in my opinion surpasses it, so I felt the need to say something. Besides, the warning about the Russian Olive tree just may save someone a lot of frustrations.

SEEMS TO WORK WELL... IF YOU CAN GET IT INTO THE TIRE
Size: 10oz, Size: 10oz
The front 11x6 tires of our Scag ZTR mower leaked air around the bead (a common problem). I bought one 10-oz bag to treat them, for about $22. No matter how much I squeezed and squeezed, it would not dispense product. Turns out a small plug of "something" had clogged the hole in the cap (see photo). This might not be a problem for the syringe version but it sure was with the bag. After discarding about an ounce of product and clearing the hole with a finishing nail, I was able to treat both tires. I drove the mower for ~15 minutes. Four days later they seem to be holding air. Previously, they went flat in two days. So it seems to be working, but I have to drop a star for a flawed delivery system. If the tires start going flat again within an unreasonable period of time I'll come back and update this report.
