Grid caps actually, and that would be the modified Bada PH-12. The brief list of what's been done to it is a new push-pull output stage to replace the single-ended one (designed to drive even 4 ohm speakers), custom heatsinks on the side of the chassis, removal of the noisy cooling fan, regulated supply for the output stage, elimination of the 2nd gain stage (which allowed the driver stage to be relocated to the side tubes, reducing it to 2 tubes instead of 3), recalculated plate and cathode resistors to get rid of excessive distortion, and a bunch of other small odds and ends. At some point I'll go back and rework the power supply to be dual rail (and make corresponding changes to the output stage) so I can eliminate the friggin' output coupling capacitors.
