Weirdest Thing Ever

[gez]

I am in Toronto, Canada...

Know anybody around there?

I know one, but it seems that there aren't many others:

Thanks

Dosent a member by the name of "powertube" work for EHX?

Puretube, and he lives in Germany. 

I have a feeling you've replaced - and wired everything up to - the wrong resistor, so finding people to help you long-distance is pointless.  You need to get someone to take a look at this for you.  Either that, or send it off for repair/modding.

But doesn't he work or have some affiliation with EHX?

I replaced R25.....

Yes, but how does that help you?  Please don't take this the wrong way, but if you don't understand how to wire the thing up (and this is something that could be cleared up within a few minutes of poking around with a DMM), then no amount of explanation is going to help, even if it's from the designer.

You need someone to look at this for you (Puretube lives in Germany).  I hope this doesn't come across as defeatist (after all, this is a DIY forum), but all the info you need has been given and it's clear from your answers that you're struggling with it.

Yes I know I am struggling wiht this...

I probbly could get this fixed but I havent had the time to sit down and di ck around with a DMM. I was just hoping for a qucik easy solution....

That's what you need to do: spend some time on the circuit with your DMM.  If it works in bypass, then the main circuit is getting power in that state.  Follow the V+ connection with you DMM from the DC jack/battery to the board, and further.  See where power is going.  Now flick the switch and do the same thing.  If your power is being disconnected, you should be able to figure out where the break is occurring.

The only other thing I can think of is that the value of the stop resistor for your new LED is too small and is pulling everything down,  Unlikely though: the threshold should be higher than a couple of volts (your measurement) and the LED should have fried.

Anyway, your DMM is your friend.  Learn to use it.

Ok I spent a bit of time with it today here is what I found

Battery = 7.62V
Bypassed (V across DC jack) = 4.73V
Engaged (V across DC jack, LED lights up) = 2.04V

When the effect is engaged the spot on the PCB where the circuit goes with to either the LED (anode) or the circuit V+ INPUT reads 0.28V.

Doesnt all that seem unusual?

Well, your battery is a bit flat for starters, which isn't going to help.  However, it looks as though something is drawing too much current. 

My advice would be 1) put in a fresh battery (or, better still, use a PSU),  2) measure the current when bypassed and compare with the current draw when the effect is engaged.  Post your results.  There should be info in the FAQ (might be the old one) about how to do this if you're not sure.

Ya I know the battery is a bit weak....sorry

This is with a 7.94V battery btw.

Current Draw Bypassed: 4.6mA

Current Draw Engaged: 11.7mA

you have more than enough info in 4 pages to move forward. read, digest, search other topics, learn.

good luck.

Totally respectable figures.  As mentioned by Joe, all info that can be given has been given.

It's possible that the schematic posted doesn't correspond to labelling on the PCB (if there is any), in which case you've wired the thing up wrongly.  My advice would be to put it all together as was and, once you've done a little reading and taken on-board a little more, tackle it at a later date.
