Have you noticed how sometimes you feel like your rig sounds worse or better than usual? The problem with analog audio gear is that to function properly, it must be powered by a constantly fluctuating power source. Power suppliers deliver an electrical current that constantly fluctuates between 5 and 10 volts. The result? Your amp and all your gear never sound the same. The solution? The BrownBox 200, which lets you correct these fluctuations on the fly.

The BrownBox 200 is a completely indispensable tool for anyone using a tube amp. This small box that you insert between your power outlet and your favorite amp allows you to adjust the voltage of the current reaching your amp. With the BrownBox you have the best possible sound, you make the tubes work as they should and at the ideal voltage, you have the same sound at all times, whether at home, in the studio or on stage.

- Voltage attenuator 220-240 V AC, 50/60 Hz, 5A, delivering up to 540W. Designed for small, medium and large amplifiers (e.g. Fender Deluxe/Bassman/Twin, Marshall 50 W/100 W, Vox AC30), it can also be used for parallel or dual amp configurations.
- Easy-to-read backlit LCD display allows real-time monitoring of voltage and amperage, also useful for diagnostics.
- Two adjustment modes for precise tension adjustment.
- Exclusive transformer, wound exclusively for tube amplifiers, an industry first.
- Equal or attenuated output voltage and 5A fuse with surge protection to prevent accidental overload of your amplifier.
- EMF neutral powder-coated housing, robust and weather-resistant construction.

I love it for my workspace! Hot tea all day
Color: Wood Grain
I love this item. The size is perfect, as I prefer something less bulky for my work desktop. It isn't as fancy as others that has the digital display screen, which is fine by me, because I don't necessarily need that. The knob and different colors that indicate the temperature range works fine. The temperature on this thing works fantastically well for me. Using it on the lowest setting keeps my drink nice and hot in a cold office. I use a heatproof glass teapot with this and its a good fit. It keeps my tea hot throughout the day, so I am able to pour smaller amounts of drink and take my time sipping it throughout the day without worrying that it will get cold. At point I almost forgot that it has an automatic shut-off safety feature when I noticed it was off. So that is a good feature to have. I highly recommend this.

Requires a very specific mug to be useful.
Color: Black
The hotplate itself gets hot enough on its highest setting where it would burn your finger if you left it one there for more then a couple seconds. However when it come to what mug you can use to transfer that heat to your drink, this WILL NOT work with just any old ceramic, metal or glass mugs. You absolutely need to have a perfectly flat bottom on it. If the center of the bottom of the mug does not make direct contact with the very center of the warmer, it will not transfer heat. So straight way plan of spending another $15 to $20. Amazon has some available with good reviews all be it not a very big selection. I'm giving this 4 stars because the description needs to be very clear about this and its not.

Great mug warmer with temp control
Color: Black
I replaced a cheap mug warmer with a couple of these for the house, and for almost the same price this is a lot more functional. I really like the temperature control and silicone surface protector. In combination with the carafe below, this has changed my life - no more microwaving coffee all morning. https://www.amazon.com/GiNT-Stainless-Thermal-Thermos-Retention/dp/B07MW5N7MS

Super Satisfied Customer Here!
Color: Gold, Color: Gold
I purchased the gold/black mug warmer. I always spend a good about of money for great coffee products and I take my time to perfect my coffee for my mornings at work. However, I get pulled into urgent meetings and just something urgent and I always leave more than half of my coffee behind. When I come back it’s cold and that’s very disappointing considering the money and time I spent to make it bc I then have to toss it. I don’t believe in microwaves and I refuse to use one. When I found this, I was super excited! It looks perfect at my desk and it works perfect! I would have liked it to be more on the brass gold like my pen holder, but it’s just as pretty! As you can see, my mug had a layer on the bottom and that made me think it may not work well, but it did the job. My coffee was super warm and it got even hotter as I left it there tearing it. I turned it one before making my coffee, so I’m not sure exactly how long it took to warm up but for me, by the time I got back, it was the peg temperature. I highly recommend this to anyone who has the same struggles. No more cold coffees! Thank you!!!

It is heavy
Size: 58.3mm, Color: Black
Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.
