Steel String Singer Tranny set and Choke for SRV

[mightymike]

Hello all first post here.
I was wondering what trannys and chokes are you'll using in your SSS clones, who makes the best,and what kind of plate voltage ect.? That is, if the SSS is even the right amp for what I'm tryin for.
(I'm really interested in cloning SRVs Dumble like he used on the Family Style Album for the Telephone Song. His last hit before he died circa 1990)


Great Site

TIA

I have not built one to date, but I would probably go with a transfomer set from an Ampeg SVT. Might be a little over the top with 6 - 6550's. But I pretty sure there would be enough clean headroom

Thanks for the reply..

Any certain year/model/voltage SVT trannies? Or are they all the same?
Which brand have people here been using in there SSS and ODS
clones?

Before you said SVT set, I had a 66 JTM 45/100 clone sitting here I was willing to use as a dumble SSS guinue pig.
Oh well....

Even If I have to start from scratch, I still want to build this.

Not sure, I would check with either Heyboer or Mercury Magnetics to see what they might offer. I would probably say the 60's style would offer the best results.

Make sure that you look at the Fender Super Twin and Ampeg SVT schematics (power amp area) to get an idea of how they operate. A little different (from the drive standpoint) in the PI and drive sections.

For the preamp section, not sure, I might start with a Twin reverb or Showman circuit and start tweaking from there. Stevies goal for the amp was MASSIVE clean headroom. The preamp from the ODR might also be an excellent starting point.

Another amp that used this CF drive was the Peavey Roadmaster. I bought one dead on ebay awhile ago with the idea of making an SSS from it but I haven't had the time or energy to do much with it. I replaced all 6 of the octal tube sockets because one was arc'ing.

Actually with 6 preamp tubes I was thinking I could make an ODS / SSS by adding an OD channel to the SS type amp.

Forgive the million questions.

How does 62 Twin Reverb Pre amp with a SVT power amp,
69 SVT PT and Choke, and a 62 Twin Reverb OT sound?

What does dogears use for Iron? I just heard his clips. WOW

How close is the OT from a 67 Super Reverb to the OT in a SSS?
I might be able to land a working 66-67 SR OT.

I also have some part#s, but I'm not sure if they were for a SSS or another Dumble.

For Example:

Output:
TF-170
1052 9716

Power:
TF-130
1052 9716

Choke:
TF-155
1052 9640


ODR = ?

CF Drive = ?


Has anyone built a SSS yet ? Or made a layout, or full on schematic..
I'm trying to round up all this kind of info. Like where to get Chassis. I noticed there were some ODS Chassis here a while back, but they were for combos. Didn't SRV use a SSS head version? Then Theirs the speakers and Speaker cabinets (open or closed)

You guy do some nice work, and there are some great players here.
Thanks for all the help. Hopefully when I get my SSS up and running I can help others in return.

Well... first off the Twin Reverb wasn't released until 63

But that's the basic SSS, although I'm a bit confused myself. The SS has been reported to be a 180watt power amp, and the SVT was 300 watts. I think the SSS was 6 6L6's output.

Scott's amps are Glassman and Fuchs ODS style.

Don't even think about it. The SSS is a monster 180 watt, the Super is maybe 40 watts. Not even close.

I also have some part#s, but I'm not sure if they were for a SSS or another Dumble.

Thx, but I haven't seen any SSS clones yet. SRV said the reason he liked the SSS was that you could crank it to 10 and it stayed clean all the way up. Jeff Beck, who toured with SRV at that time stopped touring for a few years blaming SRV for his hearing loss. Today Beck uses a 50 watt Marshall on about 3-4.

My two cents worth is that you would want to start with a Fender Super Twin. They go cheap, weigh a ton, and have all the basics you'd want: decent iron, large steel chassis, lots of pots/holes front and back.

Scotts (dogears) Glaswerks Super Overdrive 50 amp was built using a Marshall 50 watt transformer set that I sourced from CE Distribution. The choke and reverb tranny are standard aftermarker Fender Twin Reverb replacements also from CE.

That amp is based around the ODS platform with a LOT of tweaks.

as far as I know most SSS's were only 100W, but I think they used Music Man or Sunn Iron.

[oldmacman]

The basic formula for the SSS is this:

ODS preamp. See the EF86 preamp posted here, replace the EF86's with a 12AX7, bypass the 220K resistor with a 390pF or 500pF cap, and use 44M in the local NFB loop on V1B.

Reverb section from Overdrive Reverb (see files here)

12AX7 PI (standard Dumble, see the ODS schematics)

Cathode follower driver direct coupled to the output tube grids. Original SSS used 4 output tubes, but you should go with 2 if you want to maintain any semblance of hearing.

I would try a 60W Hammond or Dynaco clone output transformer for plenty of low end response. Use 6L6, KT66, or KT88 with a relatively high plate voltage for plenty of power and clean headroom.

Listen to http://www.duke.edu/~bhs3/sss.mp3 for a clip of where I've gotten with my OD Reverb clean channel - basically an SSS with 2x6L6 in the power amp.

Old Mac Man,

Are you using the SVT circuit or something closer to a Super Twin?

Which power transformer did you go with?

There were very few built, 2 for SRV, one for David Lindley, one for Henry Kaiser, One for Larry Carlton, one for Eric Johnson. Every picture i can find shows a 100W output and a Fender Twin OT, 4 6L6 GC Tubes.

I found some info a while back on SRV's amp and some info with HAD on the "Tweaking process" which I guess happened in the back room of a music store in austin. HAD did give the amp a "Skyline" mod and there was a spectrum analisys of the amp before and after. I did a search but I couldn't find it again. SRV's amp was not the typical SSS and was more or less built to stay clean all the way up.

That's consistent with SRV interviews. See Bill Morgan's site/GP interview. SRV had 150W versions and used them to replace his Marshall PA head. They provided the loud/clean behind his Fenders.

Did you mean a Fender Twin 100 watt OT, and which PT?
