A kit to convert a Marshall with 6550 power tubes to EL34 tubes, or to convert a Fender with 6L6 tubes to EL34 tubes for richer, stronger tone. The preferred English Marshall and "Tone freak" tube sound. Requires a VOM meter to set the bias and experience working with high votages. Not for the begineer. Moderate level. 45 min
The technology and illustrations are for the listed amps only. In theory it may be possible to do on other amps, but they are not supported and drawings will not apply to various other layouts for tube socket wiring.
