Triode Corporation makes a range of amps, which presumably all use triode connection of the output devices – the TRV-88SE certainly does. In many ways it's a fairly conventional push-pull design, though the external finish is certainly among the best, with and wooden side cheeks. The removable valve cover is exceptionally resonant, but the cover over the transformers appears to be filled with resin and is completely dead, acoustically.
