That link does not show a model T. The model T is so f'n heavy, the single carry strap would tear off within 6 carries. The model T has side handles. The model T is not loud...it is
stupid loud!!
I have owned my early model Sunn model T since 1982. These amps are viscious, reliable beasts with huge power/output matching transformers. There is a less preferred later Sunn model T that has a couple of tone slide switches (?) and red colored center knobs...but I have no experience with these.
I actually fell into this amp by accident in 1982, when I went from a small wattage transistor amp with an 8" speaker, so natrally I needed a better amp (rolleyes!). Anyhow, ened up calling some dude two months after he had advertised it in the local paper, and buying it. Sabbath was always my groove, and this amp carried me through the lean years of silly over hyped garbage that was so prevalent in the 1980's. Sorry, if the anti-hair attitude offends, but a Sunn is not a Marshall. Iommi's (Sabbath) Master of Reality and Volume IV tone ooze out of this amp with ease.
Anyhow, since the model T was marketed as guitar/bass amp, you can be assured that the bottom end grunt is there. I saw a print add years ago featuring BASSIST John Entwistle (The Who) that advertised 150 watts clean/180 watts distorted...and a 1974-ish retail price of $850 US dollars!
Anyhow, this head will destroy a set of Vintage 30's in a Marshall cab. I presently use this amp with a 150 watt EVM 12L in an open back cab. This amp does not have a great distortion by its own, and is greatly helped by your choice of overdrive/distortion. The "prescence" control is very good, and makes the clean power of this amp so versatile.
Past users of this amp. No spandex/big-hair here:

Factoid from the Ages: The founder of Sunn was some dude named Sundholm...the bass player on The Kingsman's 60's thrash hit "Louie Louie". sorry I forgot his first name.
