ROS-2000 PCB

We have developed a superior replacement board that preserves the legendary tone of your JCM2000 while adding several key enhancements. The result is a long-lasting, hard-rocking, tone-faithful solution for your JCM2000 amp with reduced noise and improved reliability. Using advanced electronics modeling unavailable at the time of the JCM2000’s original design, we have configured this replacement board to eliminate the issues faced today by ageing JCM2000 PCB boards.

In short, it’s quieter, longer lasting, and more resilient, but still loaded with all the tone mojo you love about your JCM2000 amplifier.

A true UK product It is designed in the Robin Hood county of Nottingham , manufactured near the site of the Battle of Hastings and supplied from Yorkshire not far from the picturesque coastal town of Robin Hood’s Bay. A smuggler’s paradise in the 18th century.   Dont worry, robbing the rich and giving to the poor is not on our agenda!

Upgraded Features

• Optimized PCB Track Placement: Eliminates all paths shared by high-voltage and bias circuits to prevent interference. Heavy duty tracking is used on the baord
• PCB Slots: Added to prevent cross-conduction at the valve sockets.
• Uprated DC Heater Diodes: Equipped with 3A rated diodes for enhanced durability
• Discrete Diodes: Replaces the monolithic bridge rectifier to improve airflow around components and for future serviceability.
• Flyback diodes :  To protect the output transformer if speakers not attached.
• Larger Heater Circuit Copper Areas: For improved heat dissipation resulting in better noise control and component life
• High-Quality FR4 Board: Ensures longevity and reliability
• Low Impedance Ground Plane: Reduces noise for a clearer sound
• Enhanced AC Heater Connection Paths: Improves performance and eliminates crosstalk
• Uprated Anode Resistors: From 1/2W to 2W for greater reliability
• Upgraded Film Capacitors: Rated to 630V for improved durability
• 105C temperature rated electrolytic capacitors for improved life expectancy

Significant Benefits

• Resolved Preamp Hum: Upgraded 3A diodes in the DC heater reduce heat build-up and eliminate hum caused by PCB conduction
• Noise Reduction: Achieved through a low impedance ground plane and improved AC heater connections
• Enhanced Component Life: Built to last with uprated anode resistors, quality capacitors and a high-quality FR4 board

Easy Installation

• Identical connector numbers and placements ensure seamless integration
• Consistent fixing points for easy setup and minimal hassle
• No soldering required to fit the board.
