Part of the 5C3 sound is also due to the paraphase inverter. You can compare a 6SL7 to a lower gain and very spacious/woody sounding 12AX7, a 6SN7 is kinda like a 12AU7.
Bruce Collins did make some excellent suggestions in the past regarding harp-mods for the 5E3.
General harp-mods from my experiences for various customers;
- big coupling caps (stock 5E3 values are ok)
- big cathodebypasscaps (stock 5E3 values are ok)
- pretty low plate- and powersupply voltages for the pre-amp (larger value dropping-resistor and/or plate-resistor)
- not (too) much highs (like normal channel 5E3)
Most harp-players do prefer 8" or 10" speakers.
Hope this helps,
