The TPA-50 (for Tube Power Amplifier) is a 50W power amplifier for guitar that features two independent and parallel inputs. It can be used with two guitar preamps and it is possible to mix the wet signals via these two parallel signal chains.
The front of the amp features Master controls for each input, Presence and Resonance knobs, along with the standby and on/off switches.
The TPA-50 is equipped with two newly developed SolidState double triode AMT-12AX7-WS (WarmStone) and two tetrode EMT-6L6-WS tubes. These AMT tubes are designed to replace 12AX7 and 6L6G standard vacuum tubes, AMT specifies that they can also be used on the amp.
You can discover these new amplifiers next month at Musikmesse in Frankfurt and get more information about the SolidState tubes on eshop.amtelectronics.com.
