Terms of Use

License to use the site

You may use JMIL to study amplifier modifications, share links to specific lab configurations, and discuss the content with others. You may not represent JMIL or its content as endorsed by, sponsored by, or affiliated with any third party — including any amplifier manufacturer, musician, estate, or company mentioned within. The lab is an independent educational synthesis.

No warranty

JMIL is provided AS IS, without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. The audio engine is an educational approximation — not a measurement tool, not a commercial amp simulator, and not a substitute for professional bench equipment. The schematics show topology, not real voltages. The historical attributions reflect the maintainer's best-effort synthesis of public sources, which sometimes contradict each other; flagged areas of uncertainty appear throughout the knowledge entries.

No liability

The maintainer disclaims liability for any decision a user makes based on JMIL's content — including, in particular, any decision to modify, repair, or otherwise work on a real amplifier.

⚠ Tube amplifiers contain lethal voltages (often 400–500 V DC at high stored charge) that can remain dangerous for days after power-off. If you are not a qualified electronics technician, do not service tube amplifiers. The lab's schematics and mod descriptions are for study, not as DIY instructions.

Concerns & corrections

JMIL is an independent, non-commercial educational project. By design the maintainer does not publish a personal contact address on the site.

Intellectual-property concerns may be directed through the hosting provider's standard abuse / legal channel — see the About page for details. Substantiated requests will be honoured.
