TGSL v3 100mm x 100mm reduced

[Nandor]

Nice work! Pay attention the 4.7uF capacitors are non-polarized! If you find capacitors with 5mm or 10mm distance between the pins you can avoid the jumper.

Thanks. I can only find electrolytic and tantal capacitors with a value of 4.7uf.

Im not sure about the smd capacitor at Pin 6 of LF353. I can see that there is a 100pf in parallel.

Is this optional? One 100pF should be enough when i look at the schematic.

[bernte_one]

could you upload layout files after you are finished

i would add something

[Nandor]

No 100pF is part of the phase shifter circuit, 1 for the Disc channel and the other for the Geb they are not optional!
For 4.7uF capacitor I would use this "https://www.tme.eu/de/details/mks2-4.7u_63-r/polyesterkondensatoren-tht/wima/mks2c044701m00ko00/"
For the low frequency of the filters is perfect.

I mean the smd component behind the 100pf capacitor in my layout.

Yes , bernte i can. What will you add? GB onboard Pot? 2 Tone mod?
Some transistors are still in the wrong direction, i dont know how i can rotate only the outline of the transistors. C-B-E are ok.

Here is the beta file (not finished): TGSL RUSSIAN THT.rar

i would do some changes for professionel fabrication

you can draw your own transitor and save as "Bauteil"
also possible to load some additional parts from 320volt.com into your library

Ok, thanks for the link. Im interested in the professional layout when its done.

[BKY1337]

Here is the missing part. And my problem area around the lf.
I changed the 4.7 to 5mm poly caps.



I also have problems with the electrolytic capacitors in the upper right corner.

I cannot find 100uF 16V elecrolytic with a diameter of 4.5mm.

[BKY1337]

Which type are the Diodes? All 4141 except the one in the upper right corner?



Im making a partslist. Which substitutes are the best for the ICs?

Do you think that I could get problems when i add a "Golden Sabre-Light" Logo?

[BKY1337]

I need to remove 1mm (0,5mm from each side). Is there a way to do this without removing the green areas?

[Nandor]

Use Schottky diodes in the negative voltage converter, they have low voltage drop.

[BKY1337]

Can you answer my other questions too? I want to order PCBs today.

I need to know the one smd part at the backside.
Then the second part at the left side.
Is the third hole where the speaker connector is for headphones?

Where do i need to connect the threshold pot?

[Toros]

You can put a normal 100p or SMD cap - of your choice

[Toros]

Yes! This third hole is needed if you're going to drive an extra headphone out

[Toros]

You have enough space on the board. Correct the location of the resistors 100r, 4k7, 3k3 and the transitors BF245 and 2n2222.
You will order a new card and it should look beautiful
