RM-10 MKIII Kit Announcement
RAM Tubes is pleased to announce on the 6th anniversary of Roger’s passing a special exclusive offer to Audiophile Foundation members. A select number of RM-10 MkIII kits are available for purchase. In addition, with each purchase RAM Tubes will donate $250 to the foundation, so purchase a kit and support the foundation. The price will be $1,650 for a complete kit which includes all circuit parts (excluding tubes), hardware, plates, frame, and transformers. The build level is rated as difficult, and you should consider yourself to have advanced DIY skills and knowledge of audio electronics concepts and circuits, as well as the proper equipment to do the job. A basic instruction/assembly manual will be provided, and you will get a schematic, bill of materials, and test data sheet, but there will be very little support beyond that. If interested, CLICK HERE and submit the Contact Us form. In the subject line please write the following exactly as typed here: Please Send Me More Information On Obtaining An RM-10 Kit. In the message box please indicate your level of experience. Be as detailed as possible, examples of projects you have worked on or kits you have built would be useful. We will review and evaluate candidates and within two business days you will receive a response with the official details of the offer. If you do not receive a response this means you have not been selected. This offer is valid until 12:00 AM December 25, 2025.
Welcome to the home of RAM TUBES. Founded by Roger A. Modjeski, RAM TUBES has made it a mission to bring you the highest quality, most reliable tubes available.
The world of tubes today can be confusing, even frustrating when it comes to selecting the right tubes for your equipment. It's often difficult to tell what really matters and what doesn't. At RAM TUBES, vacuum tubes are our life’s work. We know what matters so that you can be assured that the tubes you purchase will meet our specifications, and more importantly, your needs.
Our experience with designing tube audio equipment and visiting tube factories around the world means that we know exactly how a tube will perform in a circuit, and that's what really matters. The information we have provided on this site is based on decades of experience and our goal is to guide you in making an intelligent and informed buying decision that is right for you and your equipment.
Every tube we sell is selected, tested and graded using a proprietary computer testing system developed by Roger A. Modjeski. This allows us to sell tubes that are within 1 dB of the theoretical noise limit for that tube, so that even our lowest graded tubes will outperform most tubes on the market.
