SSS #5 PT?

[Frostbite Slim]

Would anyone happen to know what Power Transformer(s) HAD used for the #5 SSS?

TIA

[talbany]

AFAIK The Transformers in #005 are still unknown?, Dumble used (primarily) Twin Iron in his 100w SSS's, Sunn/Dynaco Iron in 150W (Iterations) from the info we know.
A. 450 VDC B+ on the 100w Twins 6L6 versions
B. 500/510 VDC for the 6550 Sunn/Dynaco versions

Tony, do you happen to know what transformers are in the High Plains Drifter and/or Steel String Singer for AN? AFAIK both are supposed to be 005 clones and 150W (to be exact the SSS from AN is a clone of the HPD IIRC).

The Steel String Sultan is a stripped down 005 it seems with 100W and Twin iron.

Hello Rootz
I am not really sure and don't keep up on what other builders use, But if I had to guess?? I would think Brandon had his custom built to his specs and IIRC was working with Heybour at the time he started building the HPD amp, since they didn't at the time require you to make big order to do a custom wound. They were really good about that!
No clue on what Taylor uses?



If it were me and I was on some kind of budget? and do a 1 off 005 I would search around for an old set of broken in Peavey's off something like an old Roadmaster should do the trick

I have no idea either. Wouldn’t surprise me if Dumble used Sunn transformers, at least if the original 005 is 150W.

I’m with you on Peavey transformers. I used Deuce transformers in one of my amps and that one sounds mighty fine and receives praise from everyone who hears it (really, no bragging). I think Peavey Triumph 120 iron would suit equally well. The power transformer has got enough juice to power 4 power tube and 5 preamp filaments. Not something i’d recommend with Deuce power transformers. You’d need a small filament transformer with the latter, at least that is what I did to be safe.

Rootz, For grins here is a quick list of all the transformers off the top of my head that I have seen on a Dumble made Amplifier

1.Schumacher/Fender (50W & 100W)
2.Schumacher/Music Man (100W & 150W)
3.Dynaco/Sunn/ Triad(150/200W)
4.Peavey / Mace/Duce/Ultra/5150 (100w &120 W)
5.Ampeg SVT Dumbleland 300 SL (300W)
6.Magic Parts/Pacific (100W)

There were also some rumor's floating around at one point that Dumble used Mercury Mags on some of his Ultraphonics conversions but cannot confirm this??

Dumble had the transformers he preferred (Above) for various reasons and stuck with them the ODS having the wider variety.

(Again this is a quick list off the top so if I missed a one off let's add it to the list )
BTW... I've played both versions 100W/150W SSS's and for me there was a big difference! and if you can afford the extra scratch to go with the 150 it's well worth it especially in a big powerful clean amp like the SSS (Even at low volumes) a completely different machine

... let's add it to the list ...

Dumbleland Special 150W with Western Transformers OT (4-8-16 switchable)
Steel String Singer 120W (1986 Price Schedule) with ?
OD-120WR #0137 (left speaker jack 8, both speaker jacks 4) with ?

[talbany]

OD-120WR #0137 (left speaker jack 8, both speaker jacks 4) with ?

It would appear that OD-120WR #0137 is a Peavey Deuce w/Big bottle 6L6GC (STR-387) For it's 120 watt rating. (Stock tubes on Deuce)

(So I will edit the Duce listing to Both 100W &120w)

That (Deuce OT in OD-120WR #0137) could be of course. So let's assume that the OT of the OD-120WR #0137 is actually that of the Deuce. What do you suspect in this case in relation to the PT (and the power supply) of the OD-120WR #0137? Or to put it another way - why do you think Alexander Dumble gives the output power of the ODS amplifiers with the Deuce OT with 100W, but the output power of OD-120WR #0137 with 120W?

And what do you suspect regarding the PT (and power supply) and OT of the Steel String Singer 120W?

[rootz]

I would need to see more detailed pictures of 137 to be sure, but the output transformer looks a lot like the Peavey/Basler one I used for one of my builds. Then again, due to the lack of better images, any judgement based on those that are available is speculative.

Maybe the 120 Watt thing was just marketing to set it apart from more standard ODS version with Deuce iron. Or maybe, like you seem to suggest, it is not Peavey Deuce iron. Might be Peavey Triumph 120 iron. Again, just speculation. Didn’t check if the Triumph was even in production when 137 was build. But seems logical that Dumble gave the amp a different power rating because it has different transformers.

Basically the same reason Peavey does? Like I said in the above post those amps were loaded stock with the big bottle 6L6GC/STR-387 (Beam Power Pentode) which are rated at 30 watts each. (That coupled with the fact that the SSS is running in class AB2 would be a reasonable assumption given the added headroom). Judging by the size (in relation to the OPT) 0137 looks to be loaded with some kind of big bottle 6L6GC type tube. But this is an educated guess. As far as the power transformer goes? Dumble generally matches the power to the output in most other Peavey loaded amps I've seen (3 so far) that have matching transformers. IIRC the Duces I've worked on would spit around 510VDC (under load) so that would put you cleanly into SSS voltage territory 500-520
Here is the Manual spec-ing those tubes.

https://frank.pocnet.net/sheets/127/6/6L6GC.pdf
Now I am not 100% certain it's a Duce or some other Peavey style transformer. Obviously you would need the amp to verify this so call it a guess based on the fact that Dumble used these same transformers in other amps and the Duce is rated @ 120W with the GC's

OD-100W #0177 with Deuce OT and PT:

A couple things
1st.I pretty sure that amp is 185 not 177
2nd It would appear that 185 has a power transformer off a Peavey 5150 100W so if he used the same Output it would also be 100W
705-18727

BTW. There are also reports (Brandon) out there that he used Ultra 120 Iron?? (early 90's) But? was 4/8/16 ohms

... HAD seemed to have no problem using these transformers ... ("Peavey Deuce") ... in his builds (see #177 below) ... (Thought I’m not 100% sure these are VT Classic transformers in this particular amp) ...

5150 / 6505
... It has 120 watts RMS output power, into 16, 8 or 4 Ohms. ...

Perhaps he got confused? I don't know the ser# to this amp (could be 177 and has Duce iron)) It does appear to be an earlier HRM w/ Peavey Iron given it has a Resistor instead of a choke (Like 185)

Dumble 177 Full gut shot (1).JPG

The picture he posted (you used) it's sitting on top of the same guitar cabinet w/ ripped tolex and white backdrop same one I posted The photos were taken by a reputable source i know. Here are the specs I got with the photos.

Here is a pic of the Speak outputs on #185 4 wires or/gr/wh/blk 4/8/16 ohms you can see the orange (16 ohm) wire heat shrunk and tied off at the tie strap.

As long as they use the same Pentodes as what's in the Duce then 120W is possible.
