The folks at Mercury Magnetics out in Chatsworth, CA simply create the highest quality transformers money can buy. Period. Today’s players are more informed and demanding than ever. They hear the differences and know that both transformer design and build-quality have a dramatic effect on their tone. If a tube-based amp is suffering from bland and unexciting tone then it’s probably related to low-end or poorly designed transformers. Within the player community no other company commands as much respect as Mercury Magnetics. You can depend on their uncompromising, fanatical build quality, consistency and reliability.
We exclusively use Jupiter Yellow Vintage Tone series and Red Astron series tone capacitors in our amplifiers. Based in Hudson, OH, Jupiter individually manufactures each capacitor by hand. You've got to appreciate that kind of attention to detail. The quality is unparalleled on the market today. Jupiter also produces very high quality ceramic and AlNiCo magnet speakers, many of which find their way into McNeill cabinets.
