The THD Flexi-50 is an American made, Class-AB, 50-watt/20-watt switchable power tube amplifier, with foot-switchable overdrive/boost and master volume control, and built-in external bias test points and bias controls.
The Flexi-50 is designed to allow you the ability to easily switch the two (2) octal type output tubes at will, for an amazing breadth of different tones. Usable tubes include 6L6, EL34, 6V6, 6CA7, 8417, 6550, KT66, KT77, KT88, KT90, KT100, 6K6 and 6F6. EL84 output tubes may also be used with the purchase of THD YJS or YJ20 Yellow Jacket adaptors. An external bias test points and individual bias controls allows the user to quickly and accurately set the output tube bias with any digital voltmeter. The dual bias controls permit the user to correctly bias even mis-matched tubes, eliminating the need for matched power tubes.
The three preamp tubes may also be easily switched with any combination of 12AX7, 12AT7, 12AU7, 12AY7, 12AZ7, 12DW7, 12BH7, ECC83, ECC82 or ECC81 dual triode preamp tubes, for an even greater pallet of complex tone capabilities.
From fat, clear, full clean tones reminiscent of late-1950's to early 1960's American combo amps, overdrive to rival the best British heads, and immediacy, clarity and "punch" of a grid-based Class-AB amplifier ... this little amp does it all!
