Bought the cable
Now need opportunity to try it
C’mon rainy weekend with no yard work!
Now that is something I need.
Take some pics when the time comes. Please.
Checked with Jim Bergantino first. He said it should be compatible
Now you’re asking for some work
My beloved cab sits amongst accumulative stuff from decades
It looks just like pics on line
I’ll Have the Berg perched among tools n such tethered to my Sunn by the new cable
At least I’ll get to hear what pure transparency sounds like thru the breath of Thor
I’ll keep y’all posted
Picked this up yesterday, along with its matching cab:
Sweet, an early one with that mongo op transformer; is the cab 2x15 or 6x12? How’s the rev/trem?
Here's my old trusty 1974 sunn concert bass head, and a new-to-me 215S cabinet (also 1974 or so).
I had this cabinet years ago, but it got lost in the shuffle. So this acquisition is a nostalgia trip.
The cabinet is a beast -- I'd forgotten how heavy - I musta been stronger back in the day. It sounds great with my other heads as well (GK and Ampeg).
These stickers were floating around inside the cabinet when I took the grill off -- unglued from the back of the drivers.
Since acquiring the cabinet, I've done a few things to improve it (heh heh):
-- I cleaned it, of course, inside and out; it was kinda smelly (mildewy). Windex and a scrub brush on the nubtex; carefully, soap and water and a soft brush on the grill cloth. The grill frame was colored with a highly water-soluble black paint, which started to make a mess, so I had to be careful with that.
-- I lined it with Walmart foam mattress topper. There were 2 thin, smelly, wimpy old pieces of yellowing foam about 15 inches square behind the drivers. I lined all the interior surfaces except the baffle, leaving the slot port opening clear. I don't have the golden ears to say how much (if any) of an improvement this made, but the cabinet sounds great.
-- I glued those labels back onto the drivers.
-- I got shiny new corners for the cabinet from aaronsher on ebay, and cleaned the rust off of the casters.
-- I got a cover from amplifiercovers.com.
I've run out of ways to spend money on this! Anyway... I've played this rig out twice at outdoor gigs and it just kicks ass.
Random Sunn sighting on YouTube recently:
That looks to me like a Coliseum Lead on top of the Ampeg fridge.
Thinking about picking up this sunn 2x15 (Beta 205). Anyway to tell if these are guitar or bass speakers, by looking at the cones?
in the old sunn amps, 15's were used for their bass amps. also the fact that it's a ported cab would indicate that it's meant for bass. they probably can't handle all that much power judging by the size of the voice coils though.
Yea I know these old cabs aren't super powerful, but the only amps I own at the moment is an Acoustic 150, and an Ampeg vt-40. From what Ive read there is 100w version, and a 200w+ version, of this cab. Guy said it says 240 watts (or something I cant remember) on the back jack plate.
Almost all of the old Sunn cabinets were ported, guitar or bass. And there wasn't nearly as clear a distinction between the two as there is now. Generally, though, 15"s were used for bass. Same for 18"s. 10"s and 12"s, usually for guitar.
The Beta amps that were meant to match with those Beta cabs were only rated at 100 watts into a 4 ohm load, that coupled with John's observation on the VC's on those drivers would indicate a pretty low power rating on that cab.
I'm more of an early Sunn guy and not a Beta series expert, but I've never heard of and would be surprised if there were two versions of that cab. My money is on one version and that version was rated around 100ish watts.
In the very early days Sunn only used two cone drivers for guitar or bass, both 15's; JBL D130F for guitar cabs and the D140F for bass.
Picked up that Sunn 2x15, that I mentioned the other day. It is a 200 watt cab. Ended up getting it for $175. Sounds great with my acoustic 150.
If those speakers are healthy, I'd say you got yourself a good score!
Just for kicks I'd pull those drivers and see how they are labelled. I have no idea where Sunn sourced their drivers in that era. In the mid 70's Sunn had their own speaker manufacturing facility, it would be interesting to see the EIA codes on those drivers.
Haven’t gone through the almost 50 pages of awesome thread yet but am fully planning to— super stoked on having picked up a Beta Bass 1x15 combo and wondering what the history is. This isn’t the first early Sunn combo I’ve owned but it’s pretty crazy how little info’s available on the web in general. Anyone else have one of these and could shed some light?
Congrats!I played through one of these at a gig 15-20 years ago. I remember it having great drive and punch.
I have one and am the original owner, bought in the early 80's. The combo came with a foot switch which allows the user to use one of the two channels or combine the channels to really drive the amp.
The distortion channel is very effective, but remember that the amp is only rated at 100 watts. the original 15 inch driver left a little to be desired. I replaced mine in the 80's with a Gauss and it's still in there.
Hit me with any other questions you may have....
Got some “low wattage” goodness going on:
Wondering if anyone knows of a footswitch suggestion for the Beta!
