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 !

+1! Edit: @thomasdf please bump me up to 4 units, and thank you for everything.

 

[thomasdf]

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

Hi guys, here it the guy, winded back (still with the white top insulation) but it goes well with the winding job. I still wait for the exact core material and shield tape but it will happen. Stay tuned!

 

[KrIVIUM2323]

Awesome!

 

[capacitorless]

2nd that!
