so how did I do?

Nice pics, I believe the first amp to be a mystic, and the blue chassis to be a two rock, no?

If it was your own designs you were protecting I'd see your point, but we're talking about Dumble's designs not yours.

If everyone followed your philosophy this forum wouldn't exist and we wouldn't have the copious amount of information we have on the ODS. There are already plenty of commercial builders building both the ODS, and SSS style amps and if someone else who is on this forum wants to enter the fray we'll it's a free country isn't it; one thing for sure they're not going to be rolling in the dough by building amps...

I'm sorry you feel bitter about sharing your knowledge but the majority of us have absolutely no desire to build amps commercially could benefit from people like yourself sharing information...[/quote]


Brandon doesn't need me to speak for him but... No one here has been more generous with his time and knowledge than here than him. A couple of these goofs he's talking about think nothing of going on other boards and taking shots at him now that thanks to him they've become "experts". Do a search on his name and look at the step by step tutorials, detailed pics, etc... that's he's done just to help out. Not to mention the chassis and other parts he went to the trouble and expense to have done and then shared. When you have brought as much as he has to the table then start complaining about him. Until then it's his choice.

First off, I posted alot of the information on the ODS that is out there, and I share freely with those I trust, and those who have shared with me. I do not owe you anything, but if you want to call me we can chat and if I trust you and such perhaps I can help you.

that is correct, its thier versions of the SSS.. not sure how close it is to the ones they cloned though.
and also brandon, ive thanked via email before. but ill just say it again, thanks so much for your help to everyone with regards to dumbles. for one the dumbleator would never be possible for me personally without your making trannies available and the super clear tutorial you took the time to post.. thanks!

Max,

I'm afraid we have a misunderstanding here. I have tried the DL phase inverter (PI) and the 12ax7 with cathode follower in a butchered superreverb amp and based my conclusions on that. I agree that the amp is the sum of the different circuit parts and that things cannot just be transplanted and work great in a system without adapting other parts of the amp (like for instance LNFB).

Flat to me is a flat frequency response. Compared to the DL PI, the 12ax7 PI is more emphasized on the high end of the spectrum to my humble ears.

All the best,

Jelle

Hi Jelle,

I see. It's complicated for me. I play/ed these things quite a lot but my technical knowledge is rather limited and so I can only describe how these beasts sound and react to my ears and feel and those pieces of techical infos that I get from the tech who does/did service these amps.

But I am really rather sure, that it's not the PI as an isolated point. And indeed, as I posted before, not much negative feedback in a Dumbleland preamp (as far as I remember).

And what comes to my mind right now: The Odysseys have a PI that's more or less similar to the Dumbleland PI. And if you listen to EJ manzamp/odyssey sounds you will find nothing dull too. Or remember Kevin Dukes: Two Odyssey power amps in his rack and nothing dull or flat in his guitar tone!

In the end it's the cook who wins three stars and not the pepperoni!

Have a great time at the amp show and help Brandon to tear down the building. A four 12 and a SSS. Holy shit!

That blue chassis I believe to be a pretty good clone of Henry Kaisers #4 SSS. the layout is totally different, but the circuit is all there, that little stack of dimes thingy is the inductor driving the Lo Filter.

The filters themselves are pretty close to the ones in RDH4, and on the other post I see people getting very close to the values.

Max,

That's my point: it all depends on what you feed into that phase inverter.

I love the cook analogy!

I understand what you're saying, but I also understand what Brandon is saying all too well. I never got into it for commercial purposes, and so I shared with a lot of people for the asking, dating back to 10 years ago. Most everyone was polite in return and some were neutral, but a couple of people showed their true colors -- and they are still kissing my ass as far as I'm concerned. Brandon is in another category all by himself and, to this day, he has not ceased to amaze me with the gratefulness he's shown to me and the generosity he has extended to everyone else. How many people have posted tutorials on how to build things, shared part numbers, offered kits at cost, facilitated cabinets and chassis, and even went as far as offering speakers at cost to the masses? I don't know how long you've been around this forum, but while in theory perhaps I would have made the same point you brought up point, the whole thing goes a lot deeper than the way I see it being portrayed in this thread. Just look at past posts and count how many amp makes share here, then you can put a list of how many amp makes hang and/or lurk here. I have a good idea of the answer, and it ain't pretty.

Cheers,

Gil

Couldn't have been said any better. Brandon would be sorely missed if he weren't here.

I doubt they'll be rolling up to divulge what they know, either.


Having used the search function alot since joining, I was suprised by the amount of FREE Information Funkalicious has given, for nothing.

Thanks for sharing what you have when you needn't have, Funkalicious.

Brandon's never been anything but helpful. Sorry you haven't been here long enough to see that.

Agreed. Brandon falls into the "Good guy" category.

Let's be completley fair here. No one designed guitar amps from scratch. The tube manufactures published the circuits and the math in the manuals.

What Brandon did was disect what HAD did to the SSS and document his findings. Not unlike what Jim Marshall did for the original JTM45 from the 5F6-A bassman.

So if Brandon wants to keep his research private he has every right to do so. If anyone else disagrees, then take apart a few SSS and document it.

Can't wait to hear this amp next week Brandon. Looks awesome, and I bet sounds even better.

[Funkalicousgroove]

Bring your earplugs, we're going to offend some delicate sensibilities!!!!!

[dr. who]

Hey Brandon would you ever make a 100w version like Kaisers? I'm also interested to see if you'll ever make the ODSR.
