Help me please! TS9DX input cap location

[GLPE]

Can someone please help me find the .047 input cap that you replace for more bass response in my TS9DX, ive already replaced one but through the help of this forum and a little research, I dont think that it was the right one. I read somewhere that it was on the small board, again, I am new to this so I dont know how to identify this cap because unlike the boards on my boss pedals, there are no identification numbers.
Thanks,
David

BTW, if anyone has a picture it would help greatly.
The one that I replaced has a big "N" under it and is on the main board.

The cap you want to replace (.047uf) is on the small board attached to the drive and mode pots. It is labeled C103 and is a semi transparent green cap. It sounds like you accidently replaced a 1uf non polar electrolytic (NP) on the main board. Is the cap you replaced metal? You need to straighten that out first. If you need them, give me your email and I'll send pics of the main, and both sub-boards.

Btw, the thread title is misleading. It's not the input cap you are changing. The cap you will be changing for more bass response is in the clipping section of the circuit.

Thanks, FW, the cap that I replaced is the exact same kind of cap as the one that you are talking about on that small board, I am going to take that one out of the small board and put it in the place of the one that I wrongly replaced and then put a .1 uf cap on the small board attached to the. The one that I replaced is not metal, it is semi-transparent green or yellow on the main board, like I said it has an "N" under it, I dont think that the "N" is to identify the cap it is just printed on the board, maybe a brand symbol or something. Now that I think about it, it seems like after replacing that cap that I replaced the pedal may have seemed to have more gain when the gain knob is lower, this may just be coincidence, and it may be a product of the TS808 mod.
Thanks alot for all of your help, I am trying to learn this and I appreciate all the knowledge found here.
Thanks,

Im sorry, but I forgot to tell you that both the resistor on the small board and the one that I replaced on the main board say 473k on them. I still dont know what the one I replaced is but I will fix that when I replace the correct one.
Thanks again,
David

I sent you the board pics. Then you can describe the exact cap location you changed.

You mean capacitors, not resistors, right? Ok, they are both .047uf.

The cap change (103) on the small board will affect the bass when the mode selector is in the "TS" position. The other modes will stay the same.

A good place to familiarize yourself with the TS is at GEO, under "technology of the tubescreamer".

btw, you can remove your email link now. It's a good idea to remove it as soon as it's no longer needed. Plenty of non-registered lurkers view the site. No need for more spam.

Thanks for the pics, I described the cap I replace in an e-mail reply back to you. It was a cap that I replaced, a .047 or 473k, yellow. In the upper center of the main board.

when I change cap 103, should it still have the same kind of ts9 tone, I dont want it to sound like any of the other modes, should it still just sound the same and just let a little more bass through?
Thanks,
David

The character of the TS mode will still sound the same clipping wise, but will have more bass (flatter mids).

The other modes use even more bass response, but have different clipping diode/led arrangements for less distortion and more output.

I know this picture is blurry but up close my camera doesn't do to well but is the cap on the left one ( marked with the white text I added ) the one it says 473 and it has 2 small "glass" doides or transistors in front if it going to a 4.7k resistor, so I should add a .1u (104) if correct? in place of it any special kinds like a poly film or whatever other kind there is.
I already added the "RC4558P Malasian chip" and removed the  470 ohm and 100k resistors  and replaced them with some carbon comp 100 ohm and a 10K for a 808 spec.


to convert p to u on caps do you take the numbers on them and do like so
move the decimal 6 places to the left? correct? and take what it says on them like 473 to make into readings like so

  47000p (473)  
.047u

  10000p (103)
.01u


100000  (104)
.1u

  22000p (223)
.022u

1000pF = 1nF = .001uF

your numbers look correct.

as far as the .047uF to change (is that a TS-9 board? The DX I think had the cap on a small board which the pots were attached to) that's probably right, but you should find a schematic and compare so you are sure what is what.
