Wienbrock Amplifiers GRINGO

GRINGO

The Wienbrock GRINGO is our take on 'the' classic mid-1950's American 12W recording amplifier now modified with an uprated power supply featuring BLS transformers, F&T electrolytic capacitors and the choice of two output powers. It is capable of delivering 18 or 30W of soulful clean right into sizzling saturation with unrivalled clarity and sustain from either a pair of 6V6 or 6L6 output valves.

A single input feeds the mixable normal and newly revoiced bright channels; with the vintage/modern switch modifying the response of the normal channel and a master tone control... simple... effective. Input gain can also be customised by swapping the standard 12AY7 preamp valve in V1 for a 12AU7/ECC82, 12AT7/ECC81 or 5751 to either decrease or increase the gain of the input.
