The design was a labor of love that started in a garage in New Malden, England. It quickly grew in local popularity, and made its way to the stage behind big names like the Who, Pink Floyd, Jethro Tull, the Moody Blues, and Manfred Mann. The legendary DR504 is synonymous with big, clean, and powerful.
Skilled amp builders, try your hand at recreating this sonic icon with our Mojotone Custom 50 amplifier kit. Click the link: https://www.mojotone.com/Mojotone-Custom-50-Amplifier-Kit?page=1
The kit comes with everything necessary to build a working unit, including resistors from Ohmite and Vishay, Mojotone Dijon capacitors, Heyboer transformers, Belton tube sockets, and potentiometers by Alpha. When you've completed the project, take comfort in knowing your hard work is protected in a rock-solid finger-joint construction baltic-birch head shell made right here in our factory.
Also included is a full-color wiring diagram which provides a faithful road map of all the right angles and mil-spec techniques which were documented from studying two original examples from the early seventies.
