monoblock amp uses one 805A tube in single ended
configuration. The driver for the grid is a solid state DC
coupled amplifier. The unit uses an internal universal
100V..240V 24VDC power supply. An internal regulator and
voltage converter provides the 10VDC,3A for the filament and
the 400VDC,200mA plate voltage. In order to fit in the
low profile base the BTA40 has 3 smaller output transformers
connected in series instead of one big transformer.
Because the BTA40 runs off a 24VDC power supply internally
it can also be powered by an external 24V DC power supply
(optional). Normally used in pairs, the BTA40 is also
available in singles. The solid hardwood base is available
in several selected woods. We normally use cherry wood but
we can use your own choice of wood on a custom basis.
Balanced input with XLR connector is available as an option.
