Rouge Un - a red preamp featuring Lundahl , 5534 & pumpkin output

[thomasdf]

Maybe you should mention that you have an original pumpkin available for study / cloning

I’d be interested in for 3min, maybe 4-5 units

 

[JMan]

Yes, true. If we have enough interest, I have an original pumpkin that I'm willing to offer up for sacrifice in order for Moby to create these.

So if folks are interested, please post here and let us know.

Too bad the availability is so poor for this part. I would love to make a 500 Series card of this preamp.

Would you be in for a Moby repro? This could make this unobtainium part available for DIYers working on this preamp, but it will only happen if enough folks are willing to join in. So far, sadly, it seems to be crickets.

 

[tk@halmi]

Yeah, I would be in for a couple of them even if it is just close enough to a gourd.

 

[thomasdf]

Well I am working on a 500 format version and I plan to share the whole design and gerbers with the community here for free ...
So if there's enough interested for the output transformers, you're just a Lundahl (easily sourced) away from the preamp
Hop aboard it's going to be fun !

Thanks so much @JMan and @thomasdf for this. You can count me in for a pair, maybe two pairs if we need to meet the quota. I’ve been eyeing this thread, but also trying to resist the temptation to start yet another project haha.

@thomasdf, I see on the schematic that the +/-24v pins are shown as NC. Will there be an option for it to run on +/-24v in a 51X rack?

 

[thomasdf]

It can absolutely be done, it’s no biggie especially at this point of the project

Great! That may also be a way to wrangle some extra interest from those who are looking to fill more 51X slots. There are even less options now that it appears the Don Classics modules are history.

 

[tk@halmi]

What is the gain switch required for this? 2deck, 7 position rotary?

 

[KrIVIUM2323]

I would be in for some transfo too. The price would define how many i would order, 4 would be a minimum i think (if price is not through the roof) ideally i would like 8 of them.

 

[thomasdf]

Awesome ! Let's keep the Pumpkin train running ! Perfectly timed for Oct 31 !
We should write that down somewhere but so far we have :
Jman : 2 - 4
thomasdf : 4 - 5
tk@halmi : 2
thelivingroom : 2 - 4
KrIVIUM2323 : 4 - 8
shabtek : 2 or more
bugfight : 2

So that's already 18 to 27 units Nice !

 

[tk@halmi]

Is there a target quantity where this will become feasible to do?

Thank you

PS: I may be able to obtain one original unit for testing purposes.

 

[shabtek]

Count me in for 2 or more

Maybe you should have a look at the previous pages .. you'd read MOQ for the transformers is 50 units and that JMan as a NOS unit available he'd send to Moby for cloning

 

[bugfight]

i’d take 2
