Big muff veroboard layout error?, 1 resistor value missing..

[finkfloyd]

Hi,

I'm bulding a BMP from (Torchys) Veroboard Layout, but it seems a resistor has a missing value theres only 21 marked , when theres actually 22, look next to R13 to the left in the below pic, what would this value be?





Thanks!

That's 100 ohms, from Q3's emitter to ground
No...  sorry, R15 is 100 ohms, then that's 100k to ground
as per tonepad's stock bigmuff schem  !!!

Dont fit that resistor .....
It will parallel R15 and I think its a mistake. Fit R15 but leave the unmarked one out.

Hi,

Thanks for the replys, I wired it up true bypass, adding the 100k resistor it bypasses , dosent work just yet, im a bit drunk at the moment , but your thoughts may be just right, it may be a mistake...hopefully, i need to rewire it, as i have been fiddling with the wiring, and ill try taking out that resistor.

Thanks

well i took out that resistor, no-go, tried without wiring to the switch, best i can manage is a bypassed sound, which sucks as i spent a lot of time on that board 

bah i think i need to buy myself a laser printer to help etch pcb's, much less hassle and a whole lot easier i bet..
