Marshall 6100LM and 30th Anniversary amplifiers.


Welcome to my web site!
This site is for support of the Marshall 6100 MIDI board.

After Marshall discontinued the 6100/6101 amplifiers it was just matter of time before the supply of now obsolete but programmed 27c64 UVEEPROMS dried up. The most common cause of failure is usually a powertube arc/short which puts excessive voltage into the heater winding which the MIDI board leaches it's power from. Every part used is what you would call garden variety, even the 27c64. The reason the 27c64 is so critical is not because of the part but  the program the part contains . Without this program it WILL NOT WORK!

Every chip i sell i program myself using new, not refurb UVEPROMS so i know they are done right and 100%
For information on returns/warranties and what i will perform for repairs please see the appropriate pages.
