My dear friend Peti Racz called me a few weeks ago. He asked for a Philips  TCA530 IC. This one is located in plenty of ancient radio tuners as power supply for the varicap diodes.
The IC is not in production for years now. It is only available on eBay for insane price. For $30-60 it is incredible and you not even know if it is genuine.
Fortunately there are circulating on the internet a few circuit what can replace it. He picked one for me, I looked around for explanation, datasheet, other notes to check if it is feasible. Corrected a few things on it based on notes and my thoughts.
My goal was simple. Didn't wanted to put a big wired in board, but something tiny, fits in the place of the original IC.
Here is the result:

It is just a bit larger than the original DIP-16 package, and substantially higher. I hope, it will fit.
Waiting for the result on the first tuner...

  1. Hello, Would you do that (replacement TCA530 in 9250) for me? How much would it cost ?

  2. Válaszok
    1. I sell this for $10 + PP. Unfortunately I had no time to setup some store for it (I will, probably on Tindie)
      Be aware. It is not a direct complete replacement of the TCA530 (according to my plans, the second version will be). It working and tested in the Hungarian Orion ST240 tuners. The others are questionable.

  3. Please let me know how to buy this?

  4. Ezt a megjegyzést eltávolította a szerző.

  5. Can it be applied to the GRUNDIG MT100 tuner?

  6. Üdvözlöm! Hogy lehet megvásárolni a TCA530 helyettesítő áramkört? Telefonos elérhetőséget kaphatnék esetleg? Vagy e-mail címet?
