Randy,
There's nothing to convert; the 4EF4A3 Mastr Progress Line power amplifier
is already designed to cover the 6m (50-54 MHz) band. My data identifies
this unit as a continuous-duty amplifier that is rated at 150-300 watts,
using a 4CX250B tube. It's a real workhorse. It will require careful
tuning per the instructions found in LBI-4100, of course, but I don't think
any modifications are needed. However, that statement applies only to the
power amplifier; the other RF components of a 6m repeater, depending upon
their model numbers, may require some modification for peak performance in
the 6m band.

Subject: [Repeater-Builder] Repeater conversion
I have access to a GE Power Amp Model# 4EF4A3
The freq is 42-54 MHz
Can this repeater be converted to 6m (easily)?
I also have the Duplexer.
