NOBAD

New old bass amp day. I swear there was a thread titled something like name some tube amps nobody's ever heard of, or something like that. I really searched for it way too long, like 20-30 mins or something. Anyway this is one of those.
I have sort of half a$$edly been looking for one of these on CL for many years.
So just for fun here's an amp that I'll bet nobody's ever heard of. (Outside of maybe Or. Or maybe Wa. Id.) I know not too many were made and I believe only for a very few years. About my senior year in HS which was 1970' I bought one of these because it killed my Silverface Bassman which had 2 matching 212 cabs, with roughly the same wattage and a single 215 cab w/JBL D140's.

So I'll bet no one here has ever seen one of these. I picked up the non working head several years ago and it sat in the closet untill about a year ago when a friend brought it back to life. It sounds great but still needs the preamp gone through and figured out. He didn't want to take the time last summer. But it's strong loud and clean.
The amp itself is a DynaCo Mark III. You see the builders were cloning the Sunn 200S bass amp. So we have here a very early Sunn bass amp clone.
Last Friday. I was cruising CL and saw a "no name" bass cab very cheap. I called the guy and snagged it. It has crap speakers (70's Rola's really more like stereo speakers) but is in amazing condition considering its 40 yrs old at least. I mean the Tolex is almost perfect and the grill cloth has just one hole in it. It's really not too heavy, probably 50-60lbs max.
So bonus points to anyone who can name it. So here's some pics and l'll be back shortly with more history and a pic that shows the name. Any guesses?

The little star bursts have a "gem" light in the center, the one on the amp would light up. I don't think the amp one would but they are blue. It would be cool to have both light up.
Just putting the head on the cab today gave me real big rush of nostalgia and I can't stop smiling looking at it as it's just no nonsense cool looking!
I'm seriously thinking of putting some good speakers in it. I'd would really like to go Neo so I could actually use it.

Cool amp. I have no idea what it is though.
I am also on a quest to find my high school bass amp, I just don't remember the brand but it too was an odd ball.

Maybe with a little work, you could get the speaker light to light up?
Does the cab starburst actually have a lamp, or at least a socket behind the jewel?
If you can lamp it up, then you would just need an appropriate voltage wall wart to power it.
Alternatively, you could tap power at the amp's light and extend it to the cab.
You could add an additional connector on the back of the cab to connect the wall wart to the lamp.
Or... If the [neg] on the speaker connector is at ground potential, you could change the cab 1/4 from a tip - sleeve, to a tip - ring - sleeve and have the + of the power for the lamp connect to the ring.
It would require some special cabling though, and you'd have to be sure not to plug things in with the amp powered on. If you are electrically challenged, maybe your friend who worked on the amp could help out.

I have Faital 15PR400 drivers in my Sunn 2000S cab. They sound really good and might work in that cab, seeing as it appears to be similar to the 200S and 2000S cabs.

Conrad?

edit: prolly not. Just reread the op and it says clone of a Sunn.

Nice amp Kirk. The knobs, being where they are on the top, make it even better.

There's a capacitor upgrade board for the Dynaco MK III sold by Triode Electronics. It boosts the capacitance which makes the low end more solid.
