Dayton DTA-100a amplifier died on me

After 14 months serving me well with almost daily utilization my secondary amplifier decided to go south.
It was something unexpected: it had loud “bumps” when turned on the last couple of times and then ceased to output anything.

I’ve brought back on of my old T-amps to drive the Indiana Line Arbour 5.04 of my desktop audio setup mentioned here: it was a good idea to keep the T-amp around.

Hopefully the Dayton will be back soon and in the meanwhile my neighbours will be happy with the lower volume.

After a full two months I finally got the amplifier back.
The vendor replaced it instead of fixing the old one: no explanation about what went wrong with the first unit.
