cont'd from the folowing post

http://www.bossarea.com/forum/topic.asp?TOPIC_ID=9119


here are the pads on R14 (DS-1) that have been desoldered and cleaned and it looks like the pad on the right still has a little (very little) solder on it, but i didnt want to heat it up anymore and risk damaging it like i did the left one..

i need to know what i need to do to it now in order to get this working

Hi kelmaur & Guys

Hard to explain - easier to fix.

We have all been really busy with our day-night contracts,
that feed the family and pay the ever growing utility bills.

I have added some notes to one of your pics.

You won't get a really great solder joint on the damaged pad,
but apply what little you can.
Ben the leg over to the next pad as shown, cut it to length.
Now solder the bent over leg to the next pad, it's the same point electrically.
And you now have done as best as you can for a home repair.

I don't think I can explain it any other way - refer to the picture.

It's 2:15AM here (really), & I still have about another hour,
before I can go to bed, and get some decent ZZZzz's

Good luck
Regards Dr. Bob

--- edit ---
I noticed that you seem to have the temp control on your iron maxed out.
Try setting the temp a bit lower, it minimizes the chances of damaging the pad/s & track on the PCB,
after-all these are just cheap phenolic & copper PCB's, and don't like/take a lot of heat.
You may have to experiment a bit with the slightly lower temperature/s.


---edit--- minor change to instructional picture below.

Hi kelmaur

Thank you for your PM.

Please understand that due to the sheer number of daily emails in my In Box.
I typically only reply to forum related issues on the forum.
Unless it is of a personal & private nature.
Not to mention the huge time differences between countries

It also gives a chance for the others Tech guys to help you,
while I'm Working or sleeping.

I hope you don't mind me posting your PM related to R14 in this thread
That way we all get to learn & understand from the questions & replies.

hey Dr. Bob..how you doing.

i have a question

i have had to buy new R14 resistors for my DS-1 Seeing Eye Mod because after doing what i was told to do in the posts in the past few days, i found that the one i had soldered and resoldered, the leads beacme a little short for what i think you mentioned for me to do

my question is, i found the same value resistors, but the one that zentropa sent me in his package was a 5% tolerance, i couldnt find any 5% tolerance resistors, all i could find was 2% resistors, will these 2% ones work? and how, if any will it affect the sound of this mod?



Yes a 2% tolerance resistor will work fine.
The tolerance just means that the 2% resistor will be +/-2% closer than a cheaper +/-5% tolerance resistor.

Besides 2% tol. resistors are typically,
much better quality Metal Film, compared to Carbon Composition.

I hope this helps
