Hello , I am just staring on the Bias / Regulator board, first stumble is the 499 ohm resistor - which way up/down?
Yellow on the top or red on the top?

 

[Paul Birkeland]

Resistors are not directional.

 

[Tabaia]

great , thank you.

 

[Tabaia]

hence no info added about the direction in the manual

 

[Tabaia]

Could i please get confirmation that this capacitor is in the correct position.

 

[Tabaia]

I think i figured it out - Could someone confirm the position of the film Capacitor

 

[Paul Birkeland]

The second way is more correct than the first, but both would work.

Hi Paul,

Thank you for your feedback.
Would it be ok to send you pictures of the boards with components and soldering for some feedback?

 

[Paul Birkeland]

You can post them here.  So far, I'd suggest either turning the iron temp up all the way or holding on the joints a little longer so they flow out a bit more.

Hi Paul,

Here are the pictures.
Thanks for your support

 

[Paul Birkeland]

Definitely more heat is needed, and a tiny bit of extra solder.

 

[Tabaia]

so, my understanding is that I should go over all the solder joints, reheat and add a little solder as well.

 

[Paul Birkeland]

Yes, when you get the solder hot enough, it will suck into the board a bit.

Hi,
I am going to get a copper chassis made and hopefully a brass plate for the dials and switches.
Would you have a DXF available ?

 

[Tabaia]

I have done some re-soldering according to what I think is correct from the instructions given.
Would you kindly have a look and let me know it this is better?

[Paul Birkeland]

I'd leave your iron on those joints a bit longer.

 

[Tabaia]

Hi Paul,
I have done a fair bit of reworking and I think it might be good now,
Would you kindly have a look over the solder as well as the component placement.
I think is all correct however since i'm a first timer it would be great to have it looked over by someone in the know.
Looking forward to your response

Many thanks Tunji

The 1N5820s and the 5W resistor have not been heated enough to be properly soldered.
