Four large Synergistic Research "Red" Slow Blow fuses in the 250ma/500 volt rating that I used for the tube fuses in my Rogue Cronus Magnum. They made for a very good improvement in resolution and tonal accuracy. I've upgraded to the "Black" which are even better but much more expensive.
$115 including Paypal and Priority Mail shipping to the lower 48.
