Dumble It is Odyssey Concert Deluxe Amplifier 100W # 015 [Super Rare] made in 1973
Illusory amplifier, Dumble 1972 Odyssey Concert Deluxe 100 W Power Amplifier arrived.
It's been a while since then, Dumble Amp came to HOWL GUITARS.
Dumble Amp, made by Howard Alexander Dumble, is now a mythical presence in the boutique amp world.
Among the fewer existences, the individuals that arrived this time will be one of Dumble Amp's serial number 15 of the early 73 years.
Odyssey Concert Amp is said to be an amp model whose production was begun by asking the owner of a club called "Odyssey Club" in the US to make a power amp that can be used on stage at the dumbbell.
As the main use in the 1970s, the method of connecting the preamplifed amplifier head to the Odyssey Concert Amp and using a unique "Dumblize" sound, or simply used for cross-stage monitoring It seems that it was.
It is a simple power amplifier that can be used regardless of guitar, bass, keyboard and musical instrument, as an amplifier that produces a clean and pure tone quality, it is the best among the dumbbell amps.
Odyssey Concert Amp is only made in the metal panel period (which becomes a black panel in the later years) which is the feature of the early dumble amplifier in the 70's, and it is said that the total production number is less than 30.
The initial Odyssey's feature is the gold metal panel in a compact cabinet size. The model notation of the front is "Odyssey Concert Amplifier". However, this individual is written as "Odyssey Concert Deluxe Amplifier" not found in other individuals.
(Incidentally Odyssey in later years gets bigger cabinet size and will only enter Odyssey Concert on Silver Metal Panel.)
Along with Dumbleland Special and Wniterland, the crystal clean sound of the initial Dumble amp.
When using a preamp or an effector of an overdrive type, it produces a tremendous sound.
It's a pretty rare collector's piece that Dumbble Mania around the world is looking for.
Then release your photo.
Initial specification gold metal panel. INPUT x 2 / VOLUME / ACCENT SWITCH
Model name in the center of the front panel. Odyssey Concert Deluxe Amplifier. If lettering is DUMBLE.
It is on the right side of the front panel. Pilot lamp, Oparate / Standby, On / Off, Ground switch.
4 Ω speaker output. On the right side is the RCA type Input
It is a serial number struck by the back panel. # 015 Initial individual.
It is a main transformer. It is a transformer made by Fender that was used for high output amplifiers such as Twin Reverb and Showman.
It is a choke transformer. Also made by Fender.
It is an output transformer. Also made by Fender.
It is inside the chassis. I do not open the interior of the dumble amplifier in particular (Dumbleland Special made in 1978 which we arrived last time, etc.), this individual is a power amplifier, so it will be okay
It is the main part of the amplifier. The backside of the main transformer.
It is a pot of bias adjustment. Pot date is 137 - 7218. Week 18 of 72 years
It is an electrolytic capacitor. Characteristics of the dumbble amplifier, tag board is handmade with rosewood.
Here too the tag board is handmade with rosewood.
It is the back side of the front panel. It is a volume pot and jack and an accent switch.
It is the back side of the front panel. Switch such as pilot lamp and power ON / OFF.
It is the back side of the back panel. It is FUSE BOX and AC OUTLET.
It is the back side of the back panel. Speaker output jack.
70s Dumble 4x12 in our shop "with Cabinet and a click here.
(Note) The cabinet is NOT FOR SALE Death.
I am also adding a high resolution of the #12
The power section is based of Mcintosch MC275, schematic attached
I am also adding the schematic of 15 with some correctinos to Aarons 12 and some remarks in yellow
I build this exact power section (except for LTPI, where I used later HAD values) and it sounds gorgeous!
Hope it helps
Thanks for posting this
Did you by chance build the same P.I as was in the Concert Deluxe? (.22 couplers 22k 2.2k) If so how did it sound with guitar?
Thanks

Hi Tony, I build the 12k, 1.2k and .1uF in a 50W, 2x 6L6 with 100W OT. It's very quick, responsive and stiff (in a good way). I joke that before you played the note the amp already spit it out lol. I biased it around 56% from the probe testing points
Definitely different than the "normal" PI (ie ODS124, SSS4, etc) which I build a couple of times, once as a 25W, 2x6V6 and once as a 100W, 4x6L6. I have never done the SVT PI (ie 002, alligator, hartman) so cannot compare with that. Although the Alligator is high on my list and definitely my next amp, once things quiet down a bit....
The tones on HAD amps come more from the pre amp, so the power section is more for how things feel in my opinion.

Great Thanks for the rundown.
I am thinking the Deluxe w/ 22k/2k2/ was designed for a larger bandwidth input signal and slightly cleaner (stiff) Also given it was for club use (Eddie Nash) possibly P.A
The .1uF 1k2 and 12K set up was voiced more in the direction for guitar possibly Bass..This one would be focused on the low end and not quite as stiff..Anyway if i were to pick one to use for guitar it would be the latter..
This however is just my opinion and folks can make up their own mind

In regard to “correct” in a historical sense:
IMO one should take into account the possibility, that at the time when #009 lost its original knobs, its original circuit perhaps was altered, too. If so, the historically correct circuit of #009 may differ from the circuit that the people of Two Rock met on their bench. E. G.: As is visible on some pictures of #009 its chassis was signed in 1978. Now ask yourself based on the ODS generations: Do you really think that a “classic” tone stack is very likely in an amp built in ’78?
So (as far as I still remember after around 25 years now) in regard to “correct” in this historical sense I have some (I admit: meanwhile rather vague) doubts in regard to the correctness of these aeras of your #009 schematic: E. g.: tonestack (I remember something more similar to the 2nd/3rd ODS generation), local feedback loops (less in your schematic than I remember), filter circuit (the one I remember looked somehow different), different power amp (the one I remember looked somehow different), power supply (e.g.: more filter caps in the circuit I remember) ...
In regard to “correct” in a practical/musical sense (great tone and feel etc.):
IMO this is a matter of personal taste and not of historical correctness. This in particular because IMO building amps 1:1 according to some specific schematic (e. g. ODS #0124) doesn’t make much sense anyway without all the parts at hand used by A. Dumble when building/updating #0124.

Thanks Aaron and Tony for posting this .
I had this idea come to me when I saw your schematic.
I see this is using 3 1/2 preamp tubes. Another single tube for reverb could be added just like the Bloomfield drive has. Then the other half of the unused 2nd tube in the schematic (that is currently set after the Hi Low filters) can drive the reverb recovery and become your Tweed Mixer, mixing the clean and dry signals.
So 5 tubes only and you have a Dumbleland with its cathode follower driven pi and added reverb!
Guy
I built this 5-6 years ago. Power amp is a pair of vintage KT88's.
Thanks for the update Aaron. That's very cool. I may try this one day too.
Max, 009 never lost its original knob (ie referring to a change to the chicken heads), the amp you are talking about is a different one, you can see by the different font in the faceplate
You do not have the required permissions to view the files attached to this post.
BTW: DLS150W #00X has a short but deep chassis with the tubes in two rows. Big knobs on the front panel with the exception of the two filter knobs (usual size).

It's ser#008
The Dumbleland Special at the bottom of the pile on the right is #008; first style "small" DL chassis (more depth, less width than later DL / SSS / ODS150W chassis) with seperate face- and backplates - like 1st generation ODS or Winterland #003.
Correct. Thanks for the complement and the link to this post. Wow, how the time flies. AFAIR I liked # 008 a little better than # 009. Canned SRV, so to speak.

Max Please do not get my post confused with a compliment!.
it was not. Simply pointing out something you forgot..
