I will be grateful if anyone could tell me the name of manfacturer and where
I can buy the semiconductor ponents called BUP30, Component is used in a
battery inverter.

Regards,

How can replace a BUP30(NPN) one with TIP(PNP) one? No way!

I'm trying to repair Panasonic NV-G40 VCR Power Supply
(VEP01338A / VEK3702 / VGH1476-1). So far I have found
three blown components:

D17: diode SV0381,
QR1: transistor? A143TA
D12: zenerdiode with just color code: red and black

Any ideas where to find specs for these?

It would also be usefull to have a pinout for a hybrid
regulator STK5340. It has eight pins and number one is ground.
In the SMPS-hybrid-FAQ -file the closest is STK5333.

I will appreciate any help.

Hi if u want 0 to 32mhz in 1 hz steps

clock 24bit counter at 64mhz feed into 24bit comparater use the 64mhz clock (modules avaliable). For bit 1 use the clock directly.This forms count to x. then feed output into bi-stable this halfs frequecy to 32mhz and gives u 50:50 duty cycle. 3x 74ac521 8 bit comparators could be used not a=b outs fed into a 74ac10 3 input nand this would generate MR for 2 x 74hc4040 by philips which are garanteed to 79mhz clk. with the 3 x 8bit latchs for the count to x value should fit on a 100 by 100 pcb which u can get 5off made out in china for 10usd.

Good luck and regards Roger G1BFK

Yes, a DDS is the way to go, as long as a little phase noise is acceptable.
But, you won't be able to build this with 74ACxx parts, no way they will
clock at 64 MHz. I don't know where you found this 79 MHz spec, I see 24
MHz, but note that the 4040 is not a synchronous counter, it is a ripple-
carry chain, so the total delay through the string of FFs is 30 ns PER
STAGE, so 360 ns! So, there is no way to decode this as a count, as it will
have a time skew of about one clock time every time one of the FFs toggles.

I've seen replies to old posts like this, and it can get a lot worse.

Someone asking about Linux, whatever the reason someone replies to an old
post in the first place, once the thread has been resurrected, someone's
bound to say "you're using an outrageously old version of Linux, you
should upgrade immediately". Indeed, the problem might not be there if
the poster was able to use a later version of Linux, but it was cutting
edge back then.

The real trick is to be able to ask the future a question, and get an
answer back in the past. Then someone fussing with this back in 1999 could
just wait, and now the solutions are quite different from back in 1999.

I wouldn't discount the usefulness of advice like this, in a
repair-type forum, provided the whole thread is presented and not
'snipped'. These tend to be searched by people who aren't interested
in chatting, but are just trying to fix something that is similarly
outdated.

Knowing that a problem existed, and how it was solved in 1999, may be
more relevent than any you-tube video made since...

A lot of traffic is lifted whole by people trying to bulk up
non-usenet vehicles, often with dates subverted.

but yeah....check the date

Just idea to get people thinking. 74 f Series would be better, more hz error the lower the output freq. also square waves best for saturating switching mixers and no chance of hysterisis.
i didnt notice the date of post comes close to top of search list though.

Note the original poster.

He said VCO - Voltage Controlled Oscillator.
And he said it over 16 years ago.

I am glad the resistors and capacitors are only a few cents. If I need
only one or several, I always get atleast 10 of them. Don't usually
loose any if I do. If I don't or the part is several dollars or more
and I get just the required ammount I usually drop one and spend lots of
time looking for it.

We call that here the "umbrella effect". If you have an umbrella with you it
does not rain.

Plus most distributors won't sell you less than 10 at a time.

Is 2SD1555 can be use to replace from D5703?

Can't answer about cross-reference, however MCM had the 2SD5703 in stock
a few years ago, and may still.
