Well, I lied and didn't post my Sunn yesterday. I got it a couple years ago for $300 shipped, and since it's pretty heavy I reckon at least $25+ of that was for shipping. The seller was a fellow forumite on a small closed music-collaboration forum I sometimes post on (even though I don't "cyber-jam").
It's pre-'69, I'm told one can tell by the type of transformer used but I dunno anything about technical stuff. It is a real basic single channel amp, somewhere around 60W or so, with no modern features at all. I usually have the volume at around 6 for band playing, which has just a bit of tube breakup, but I use a pedal for true distortion sounds.
In addition to the Kustom cab (see photo a ways above), I've gigged the Sunn with my
80's Risson 4x12:
And my DIY 2x12 (made from a gutted Crate combo) with a couple silverback Celestions stuck in:
The Sunn is actually a bass head technically, and I've used it as such as well.
