240V stereomour

No problem with the ohm,but how can I check the wattage of the resistor ?

You can't really do that, other than finding the part number and reading the datasheet. 

The part that we include with the kit is a 3 Watt part that seems to be a bit conservatively rated.  There are 2W parts that are indeed much smaller.

Thanks again for your replies.But unfortunatly there are also 2 screws missing for the terminal strips screws.I will place an order for replacement of these two screws and also for these two resistors if possible. Because i couldnt find inch screws in my country.I think I am a little bit unlucky..

Hi,while soldering Ac filaments of the 9 pin socket,I've noticed that one lead is different.I think it's in the reverse position.Do I need to fix this lead or there won't be any problem for connection?

Can you be a bit more specific about page number and instruction? 

Also, if you're missing a #4 screw, a similar M3 screw will likely work in its place.

One lead (solder part) of the 9 pin socket is in reverse position,it looks like it's in opposite direction.

And for the screw I tried too many metric sizes but i didn't find suitable one.But yesterday Mrs. Eileen send me the screws and resistors.

Well that's odd, that pin of the 9 pin socket has a PC board pin instead of a solder lug.

That pin will still work if you'd like to use it, you will have to carefully wrap your wire around it. 

That is very unusual, I don't believe that I've ever seen that production error from our socket supplier.

It was hard to explain without a picture .   My only concern was,there are two cables wrapped around this pin.But I dont think that will be a problem with the connection..

I've finished the assembly today.But unfortunately there's no sound in left channel and there are cracks,pops in both channels.I've changed the inputs and tubes but it's allways left channel.I don't know where to start.Resistance check looks okay,tubes glows properly.But I think there are some problem with AC/DC checks..  2a3 tubes looks 2 volt instead of 2,5 for example.

[Paul Birkeland]

The place to start would be with posting your DC voltages.

Volume pot has burned when I last turn on the amp.. Can i still make voltage/Dc check ?  Should it be plugged to the electricity ?

[Paul Birkeland]

Can you take a photo of what your volume pot looks like?  And maybe some general photos of the build.

It would be very unusual for the pot to dissipate any heat whatsoever. 

[srhombeus]

I will post the pictures.Can i still make the voltage checks? From manual,I understand that the amp should be turned off and uplugged from electricity while doing voltage measurement?

The amp has to be plugged in and turned on to measure voltages.

I checked again the solder points.But now,when I turn on the amp,there's no smoke but there's some sound like small explosion.. when i hear it,i turn off the amplifier.I don't know where this sound come from.And now,the two leds near to the volume pot doesn't glow.  I checked the fuse,there's no problem with it.It's working..
