Yuan-Jing TA2022 2 x 180W Audio Power Amplifier Board
I have an old gainclone amp that I don't use anymore, with an overkill transformer that would meet the specs required for this.. it wouldn't be more than 20 minutes to swap stuff out and give it a try.
It would be powering a set of Speedster TMMs, replacing a spare Onkyo SR-707 I've been using (still would use the SR707 as a pre-amp)

I bought one years ago, never got rid of a hum on one channel. Annoying as I'd custom ordered a transformer for it.
Another advert that lies.
It has an absolute maximum supply voltage of 80V (±40Vdc)
The max power is 60W into 8ohms and 90W into 4r0 dummy resistive load.
It is NOT a 180W+180W amplifier !

The board is marked 230w + 230w
It also states into 4ohm but other adverts state NOT to be used with loads lower than 8ohms.
100w BTL should be possible with the right load and supply.

I actually scavanged my board for parts as myself and others, don't remember what thread/forum now, had problems with hum on one channel. IIRC there was some design flaw. That may have been fixed now though as I got my board years ago.
Not necessarily.
TA2022 is rated 90W RMS per channel, +/- 31V rails, 4 ohms load straight in the Tripath datasheet, so a bridged one can supply 180W RMS into 8 ohms , so only ad error I see is labelling it a 4 ohm capable amp, although they seem to set it straight in ad body, so I wouldn't crucify them just on that.
Since they use two TA2022 per amp, 180+180 W RMS looks quite doable and within ratings.
