I wonder how "authentic" these TDA1034s could be . It has an NXP label but it is not listed on the NXP website.

Hey guys, just to let you know that I recieved the specimen (thanks to @JMan ) and it's waiting for the deep analysis. I really can't thell the price before I find out the core details. I believe it's properties and minimum order quantity will define the final cost. Stay tuned.

Awesome ! Thanks

Hi guys! Finally a progress. Pumpkin is "on the table" . I have all the parameters and the winding details. Now the parts need to be hunted. It will take some time again but I don't give up. Please stay tuned. Thanks and Happy New Year

 

[tk@halmi]

Oh, wow!

 

[capacitorless]

Count me in for 2 or more. We should be getting close if my math isn't real fuzzy.

 

[thomasdf]

Awesome ! Many many thanks @JMan @Moby !

Okay

 

[toffifee]

Interested in two!

@thomasdf I've re-thought things (again) and I would be glad to have a total of 6: 4 for a pair of 2bus/summing setups that are WIP and 2 for mic preamps.

In 2008 I made a single sided PCB layout for two ISA 110 preamps on a Euro PCB (100 mm x 160 mm). Copper side has been done with one of my CNC machines (isolation milling). Look at how the copper has tarnished...

Unfortunately at that time I got the "wrong" NEVE pumpkin transformers (they did not have the tertiary feedback winding), so the PCB is sitting unused since then.

That is why I would really like to get two of the Moby transformer recreations
