@Void118,,,Thanks for the help,,,I will try to decrease the capacitor. @Walkman,,I made your pcb and placed everything correctly but I still cannot get it to work. Do I remove the 100nf capacitor? And is there anything else I need to do? Thanks, Marty.

Hi friend sorry to late for answer.

cat_fm_v1 for only 100nf removed.

[walkman]

Rebuilt Cat_FM_V1 for pcb.Tested and work.

Thank you Walkman,,,Can I use BC327 instead of BC557, and BC337 instead of BC547? Regards, Marty.

Hi Marty1963,
BC557 instead BC157, BC558, 2N3906, 2SA1943, BD140, S8550, TIP127, TIP42
BC547 instead BC549, BC636, BC639,2N2222, 2N2369, 2N3055, 2N3904, 2SC5200

@Walkman, I'm very grateful for the help. Thank you for the alternative list you posted. I will add it to my reference folder for the future. Regards, Marty.

It Is mistake, 2.2uF plus must be connected to emmiter, so this Is right connection

Friends,

If you want I can arrange youtube stream to answer all your questions related to Cat-FM schematic, what do you think?

Hi Marty1963,
BC557 instead BC157, BC558, 2N3906, 2SA1943, BD140, S8550, TIP127, TIP42
BC547 instead BC549, BC636, BC639,2N2222, 2N2369, 2N3055, 2N3904, 2SC5200

What a stupid advice (((Use transistors in TO-220, TO-126 instead of TO-92 ... Transistors are boldly replaced by BC327 and BC337...
Moreover, they have better parameters.

@Void118 and @Walkman,,,,Thanks for the great project! I made your 1st original pcb and it works great! Thanks Walkman for your layout,,it works great too! Really pleased with both of them!
@Walkman,,,Would it be possible for you to make an SMD Version with Vibro motor instead of LED's please? Sorry if I'm asking too much. Thanks and regards, Marty.
