electro harmonix question

[fatfoot51]

Hey, it's me again.. I have an interesting question but it has to do with a layout... Since all the schematics I've looked at don't have the parts in question, rather than guess I thought I'd ask all of you, the panel of geniuses..A picture is worth a thousand words...Maybe if I don't help myself I can at least probably help one of you, inadvertently...http://eu11.stripper.jp/pulcino/blog/archives/cat_electroharmonix_deluxe_bigmuff.html  This is the link... I'm not sure I have the permission to use it but this best illustrates what I need to inquire about... Do you notice the area in the middle between those two pots? Okay, there are three little cans in the middle... Yes the polarized electrolytic capacitors! The tops are facing you... The gray one in the middle above the blue cap has a resistor between it... I can't tell what the value is... Mine is burnt... The caps on mine are 30uf and 1uf... The print has them listed as some other value... The gray cap next to the other gray cap that is above the blue cap has blown up on mine... Is that a polarized 30uf as well? I don't know it's gone also!  So to recap, the culprits I'm looking for are the value of resistor between the two polarized caps in the middle and the value of the other gray cap next to that group of three... Thanks!  Oh and also I have a question on whether my input wire is in the right spot... That would help greatly also... This is the deluxe big muff with series parallel switch... C'mon guys please ...Thank you so much!

The caps in the upper right hand corner are 220uf (grey) and 470uf (dark blue).  The resistor just above that pot, but below the grey 220uf cap would appear to be 56 ohms (green-blue-black), which would suggest it is a current limiting resistor for the power. 

I looked through the schematic but that value doesn't seem to show up.  On the other hand, the entire power section, including the 220uf cap and those two 1N4001 diodes (black with white stripe) don't show up either, suggesting that the power supply (including the transformer) is left out of the drawing for simplicity.

If the power supply caps are old and not up to spec (i.e., essentially shorting), that would increase the likelihood of the circuit drawing more current, thereby blowing up the 56R resistor due to excessive heat.

The resistor markings appear to indicate 100R (brown | black | looks-like-brown | would-almost-certainly-be-gold).  I'm not sure which gray cap you are referring to.  If it's the axial one (laying down under the white wire) I read it as 22uF.  If it's the third member of the upright trio, the cap markings are not visible in the pic, but I would guess it to be the same value as the other gray member of the trio.  Is there no possibility of cleaning the fried cap to read the markings?  Or by "gone" do you mean missing?

Edit: The resistor I'm describing is the one between the blue and grey radial (upright) electrolytic caps in the center of the board.

Thanks guys! I appreciate the help!

Hello! I hope everyone had a nice thanksgiving.. Recently I'd have to say that I'm thankful for the internet and you two guys,GGBB and Mr. Mark Hammer for being very helpful after a long string of dead end leads... We have life ladies and gentlemen! I could hear the deluxe big muff hum after I soldered the missing parts and put the input wire back in the right spot by guessing... You two guys are geniuses I must say! So thank you oh so very much!  The compressor circuit is confusing since I get a high pitched squeal but if I roll off the comp/volume and the threshold on the box the distortion is killer!  Parallel works better than the series where there is a noticeable volume drop but I'm still glad the thing works since its been dead for a lot longer! So once again I appreciate you guys for bringing my year and a half long search to an end!
