WOW. Now wer getting somewhere!

On TDSL it says that they need 13V @ 2.6A, which is alot but not impossible. 67.6W heater power for a pair. They definetly look the part, and the anode voltage doesnt look too bad. If theyre 500V than they will run ok off a 350-0-350 transformer...right? Maybe not full blast but at a decent power level.

If you ever decide to get rid of that pair please give me a shout.

They may not be the classic coke bottle shape, BUT they do look cool anyway. Even cooler than coke bottle valves perhaps. @ 33W of heater power i bet they glow ALOT too.

EDIT: Just saw the post about the KT88's. They seem to be very sought after by audiophools, and therefore overly expensive.
