Can you tell us more about the circuit? It's hard to imagine a commercial product where you can swap a 6SN7 for a 5687 and vice-versa (the two tubes are so physically different). Also, 6SN7GTA/GTB and 6BL7 will all operate at the same voltages required by a 6SN7GT, AFAIK. Granted that the GTA/B has a higher max plate dissipation and max plate voltage compared to a GT, that does not mean that one must run them at higher voltages or current. Also, how does it achieve OTL-ness? Is it capacitor-coupled? Most preamps are, and this is not unconventional at all.
