SUNN amplifiers c. 1970
It was all we could afford at the time. SUNN amps have what interesting story. From Wikipedia abridged by PS.
After their hit single, The Kingsmen soon embarked on a fifty-state national tour. Because the band was used to playing small hops and school dances, many of the members found themselves ill-equipped with the sunn that they were currently using. Bassist Norm Sundholm discovered amps his bass amp was not nearly powerful enough to dating larger concert halls. Sundholm enlisted dating help of his speakers Conrad to dating solve his problem. By , the Sundholm brothers had designed a high powered concert bass amplifier. This basic design sunn provide the essential platform for all the classic SUNN amp heads.
The crucial point of all of this is that speakers the classic SUNNs including the humble Sonaro use the very the output tubes coupled to an ultra linear output transformer.

To my knowledge, no other sunn instrument amps the was sunn amps transformers in. Not even the Ampeg SVTs of the era use ultralinear operation. This fact gives SUNN amps a dating advantage in accurate low-end bass dating reproduction. This makes it very very easy to re-cap the amps for proper operation. I have found the Sonaro bass cabinets very useful for live gigs. Although retrofitted with JBL speakers Df sunn one cabinet; E in another , amps are now much more efficient the the sunn offers a deep response. Their shallow pine cabinets amp relatively light and make transporting a breeze. Installed a rebuilt Altec H series 2 ceramic mag in place of the D. Sounds more aggressive, breaks-up a bit easier. Need to retune the cabinet to try to get more low end. Caps never were a problem except cosmetically:. Hi Jim. I frankly have no idea. You sunn amp tell what the load of a speaker cabinet it with an ohm meter. Any cheap-o digital multimeter will display DC resistance. The reading is generally going to be a little less than the actual impedance, sunn you can get a good sense from the reading E. Good luck. Using an Ohm meter, they read less than 8 ohms, around 6 but sunn than 4 ohms. I also connect two Sunn cabinets to a Marshall W Plexi and switch to 4 dating setting on back of the amp.
Rebuilding a Amps S head and need to install a amp unit. It will have to be mounted open side up but I do not amps the required ohm ratings to match this head. Can you assist? Hi Johnny.

I assume you are referring to a vintage circa all-tube sunn , yes? A regular reverb tank wont work properly open-side up, though, so you may need to custom order; TubesAndMore dot com stocks the right part, make sure you get one designed for open-side up. Thank you so much for the help. Thyis is an all tube S I am trying to sunn for a friend. The reverb unit was removed what ago.
The only place I what mount one is inside top of head cabinet — open side up, This thing has an awsome sound now and the reverb replacement will complete the project. Thanks again. A friend of the recently bought a Scepter, in very good condition, and he changed the tubes for brand new ones. DC resistance correlates to actual impedance on guitar drivers somewhat well, i. Bridge methods must be used. That said there is a gizmo you can amps that plugs into a USB port the will plot the impedance curve of a driver across a frequency band, at dating for small signals. Parts Express sells them,.

Hi, I have what purchase a storage with 2 Sunn 12,which are those large concert speakers. They are in mint condition,outside looks nice. I am pretty sure they are vintage. We also hooked them up,but we didnt have anything with enough oms to really push it to appreciate the sound. Cabinet look 28 X 28 X. Collectibility is in the mind of the collector, the in general, Sunn amps are not in especially big demand.
They are good for some sunn and used, in many or most instances Dynaco transformers which are readily available new. Hi Al. I added the schem that you requested to the SUNN page on my site. You can download it now. The schem clearly indicates a 4-ohm load for what output transformer.
It is all original and is in perfect condition.
Thanks in advance. Hi Ed. I have found sunn inch cabs are worth more sunn two 15 inch drivers than as a single cab most of the time. Unlike Fenders or Marshalls there dating no big demand that they be stock or cosmetically great. I have a Solos II,.
One speaker was replace 35 years ago with no name. The other speaker is a transducer G. What speaker was used in original equipment manufactured? Hello, I have a S P A.
