Hexfreds, like a schottky.  I think I know what your talking about, at least what they look like.  Is it for a power supply upgrade? fast acting quick recovery diode. I think this unit has it, but that would be strange that the silver fish audio 1...

The el34 run the coolest, the KT88s run hot for sure.  I'm thinking 4 EL34 during the summer days, (ran cool actually) and I can add a quad or two for the evening hours, if  the occasion should arise... Yes wonderful heaters in the winter months, ...
