Q & A / Model T reissue headshell specs
« Last post by Blown_Petals on January 21, 2021, 12:11:31 pm »
Hi all,
I'm new here. I recently acquired a 1998 Model T reissue (Fender Sunn) but unfortunately it was damaged in transit and the headshell was broken.
I'd like to source a replacement headshell and I'm wondering if the dimensions are spec'd anywhere? I'm not certain that the 1990s Fender reissues were the exact same dimensions as the original Model Ts...
I checked the Fender site but the Model T spec there doesn't include the exact cabinet dimensions and hole placements where the screws secure the amp to the cabinet.
Does anyone here have that info by any chance?
Or know someone who makes replica shells for the Model T reissue?
Thanks in advance!

DIY / Re: Power Transformer for 2000S
« Last post by Soundmasterg on January 20, 2021, 08:42:44 pm »
Hammond Manufacturing, which makes a replacement line of transformers for Guitar amps, has released a model made expressly for the 2000S. Their model number is 290S2Z. It has the 55V bias tap and a 4 Amp 5 Volt winding for the rectifier tubes. Unfortunately , only a 117V 60Hz primary.

That's good news for anyone who needs a replacement. I wonder if it is meant to be a replacement for the earlier Dynaco transformers, or the Schumachers? I'm sure it would work in place of both but I wonder which one it is emulating?

Q & A / Re: Conversion of 215 to 2x 115
« Last post by Isaac on January 05, 2021, 11:43:58 am »
Random thoughts.

From a distance, they don't look too bad at all.

Yes, looks like a 215S that has been chopped up.

Particle board is not a Sunn thing, at least at the time. Always plywood.

Why? Easier to move, can use just one for smaller gigs.

I had a 115S, way back when. I regret selling it. Of course, neither of these chop jobs is a 115S.

Good luck!

Q & A / Conversion of 215 to 2x 115
« Last post by krokodilen on January 05, 2021, 09:03:11 am »
Hi everyone!

I recently bought a Concert Bass amp (silver face) that came with 2x 115 cabs. It's a renovation project - the amp blows fuses and the speakers have been swapped for some cheap PA speakers, so the lot was sold to me for about $150.
These don't pop up very often here in Sweden and I consider this to (hopefully) be a bargain once the amp is repaired. Have a friend of a friend who's good with restoring old pro audio gear so will be getting some help from him with the amp.

I didn't pay too much attention to the cabs at the time I collected the stuff. But after a closer look it's pretty obvious that one of the previous owners totally butchered, what I guess is a 215s, in half... and certainly not the best job at making two individual speaker cabs out of it. (WHYYYYYYYY!!!)

My plan with the cabs is to do a better job at converting them to 2x 115.
(Figuring it's too much of a hassle trying to even attempt to restore it back to a 215)

So... to my questions:
  • I've read a few threads and am trying to figure out what speaker cab I have. What do you think, is it a seventies 215 that came with the amp at the time?
  • I also read that the 115s cabs at that time had the same inner dimensions as the 215s which was basically two 115 attached together. So the conversion should in that case work, given it is done properly?
    • My idea is to strip the cabs, replace the MDF with birch plywood, new tolex, new corners, new grill cloth, new rubber feet,  new speakers, etc. And if I can find them? new SUNN logos.
  • What would you guys do?
Really appreciate your opinions and any tips and insights you might bring to my coming project.

I will post more about the progress of the restoration on the amp and cabs in a separate thread at a later stage once I get started.

Cheers!

There are a number of pictures of The Who playing with Sunn Orion and other Sunn amps.

Q & A / Re: Coliseum 880 Questions

On the other hand, a lot of people like a hi-fi sound, and that was Sunn's approach.

Q & A / Re: Coliseum 880 Questions

I dug up an old Coliseum 880 from my collection. Plugged it into a couple of cabinets from my bass rig. I hate to say this, but it just doesn't sound very good at all. The Distortion and Sustain controls are not worth using. The EQ is not to my taste, it works but doesn't take me where I want to go. I think I could make a better sounding preamp (which could just be plugged into the back if the amp. A couple of mods would be necessary to make the power amp less HiFi sounding.

Compare the attached photo to your amp. The red arrows point to text on the back of the amp that explains the function of the jacks that are the subject of your question. If that piece is missing from your amp, look around on the internet for a clearer picture.
