12BH7A Valve
Robert814, 14.10.2013
This is one of those rare valves that has a tone character all of its own!
The only amp I am aware of that already comes with it fitted is the Tubemeister 5. Not any of the other Tubemeisters.
If you have another amp with a 12AU7 output rated at around 1Watt, then you can probably simply unplug the 12AU7 and replace it with a 12BH7A. I've done this in my Traynor Darkhorse. The Palmer Eins is probably another good possibility, or the Randall RD-1.
The tone of these 12BH7A's is much warmer than the 12AU7, but none less powerful. Hard to describe accurately, but perhaps a little less crunch and a bit more growl. If you want to try a different tone it's a lot cheaper to try a different valve rather than buying a new amp.

For all you techies:
The 12BH7 originally was designed for television frame output, which is lower impedance than audio output, and therefore higher current. There is an impedance mismatch into an audio output transformer, but so what if it sounds great!
This is to all intents a more rugged and powerful alternative to a 12AU7. The gain is just as low, (Well 17.05 instead of 16.94 and Anode current 11.5mA instead of 10.5mA), so it's more rugged! The only uncertainty is that the heater current is double that of the 12AU7 at 600mA instead of 300mA. If I'm unlucky, the mains transformer may struggle with the extra current. If I'm very unlucky the mains transformer may burn out. If the transformer does not appear to be overheating, then the tube/valve should last longer. My choice, but I am aware!

Great!

It is a very good tube. I've installed it into my Blackstar HT5, replaced a quite old one from Sovtek. It made the amp shine.
