Classic DeltaPulse in new SMD revision

[Emersonpaz]

Excellent job congratulations post videos I am curious about your performance
What is the manufacturer of this friend LF357N? I ask because I recently bought the LF347 and it came with the same symbol.

It looks like National Semiconductor

@StarShina

possible to send one pcb to germany, or the pcb design files?

День добрый!
Интересует Ваша плата и возможность ее заказать (не нашел как здесь писать личное сообщение).
Также интересно как прошли испытания и монтаж в корпус, как организовали питание.
Спасибо.

Hi Starshina,
I like the look of your SMD PCB just wondering if it is 2 or 4 layer and if it is 4 layer what is your stackup..?

[TufaN]

PCBs are ready.
I'm starting the assembling.

I wonder. This smd version worked and how efficient is it. can you make a video?

[GeoMax]

SMD version is nice... but nothing for the DIY community. I am sure the majority of the forum members will have problems to deal with SMD soldering. SMD is something for commercial manufacturing only.

[Carl-NC]

SMD is not difficult if you stay with the larger package sizes. 0805 passives and SOIC/SOT23 are quite easy to solder and require only a moderately decent soldering iron. I routinely go down to 0402 and MSOP/TSSOP/QFP sizes, and in an emergency will even attempt DFN/QFN, but for these smallest sizes you need a really good soldering iron, a heat gun, and a microscope. StarShinas board designs look very DIY-friendly.

starshina is a rank in russian/soviet army. not so big, but big like soldier high one. not officer consist.
odna schirokaja lychka we say. on a pic.

[ArchibaldSTM]

For starshina ... Why show off your photos and show off your device if you don't share files for assembly? Do you think we are very interested in all this?

KT 315 is a low-power silicon high-frequency bipolar n-p-n transistor, produced in the USSR since 1968 and produced in Russia to this day.

ahaha! now everybody knows kt315. and maybe you will tell us american analogue?

Whoever had misfortune to try to repair this thing; knows about KT315 and many other russian bijous!

It is fed up with those transistors, never works alright, from a very start, fresh from a store it is not working alright at all.
Probably the very worst tv i have ever tried to repair... back in my old radio-tv days...
