The Vincent SP-T100 looks close

"The SP-T100 is a hybrid mono block with tubes in the input stage where voltage is amplified. The power output Amplifier circuitry works without feedback."

Nominal output power Class-A 8 Ohm: 10 Watt
Nominal output power RMS 8 Ohm: 100 Watt
Nominal output power RMS 4 Ohm: 200 Watt

Thanks, James. I never heard this amp. I looks this company does a lot of consumers mass-market audio. Also the amp looks very fishy for 100W in class A. I do not see any forced cooling and with this given dissipation surface it should boil at 100W of class A.
Oops, a quick search indicates that the amp is a marketing fantasy:

“A vacuum tube-based 'Class A' input stage configuration complements the solid state output stage, which operates in pure 'Class A' for the ultimate in rich detail and imaging for the first ten watts. Above ten watts, the Vincent automatically switches to 'Class AB' to deliver over 200 watts of power for effortless transients and drive capabilities.”

How damn smart! To be proud that the input stages ruin in Class A is defiantly a big compliment for an amplifier for TV sets!
