Noise issue with Millenium 2 Plus with Signal Shunt

[Scruffie]

Hey all,

I had a fuzz pedal I built that oscillated pretty badly in bypass so I thought i'd give the millenium bypass 2 plus a go...

I made this vero for it, first go my LED blew up after a minute or so, so I stuck an extra 10k resistor inbetween it assuming it was just ommited from the schematic and that was my own fault http://www.geofex.com/article_folders/mill2extn/mil2plus.htm



After this though and when the pedal and LED were working fine I noticed in bypass (and active) there was a horrible background hissing noise, now I don't know if I wired the millenium up wrong but I thought that the positive lead of the capacitor just went straight to the input of the circuit in question, now it's possible I overheated my transistors as I removed them several times when trying to figure out where the hiss was coming from before I went for the simple solution of disconnecting that cap from the input.

Anyway, I'm just about to build a Dr Boogey up and wanted to know if i'm about to suffer the same fate before I waste money on buying a DPDT and then having to buy a 3PDT later.

So any clues? or was it bad luck, I suppose the electrolytic could have been leaky as it was just out of my spares box but I did try some other capacitors stuck in parallel with it and it didn't make a blind bit of difference.

Wiring, soldering, parts pinout.

Wiring fine, all nice and short leads... it was twisted around with the ground and 9V going to the millenium board, a source of noise? Tested it with a battery and DC jack seperatley though and there was a filtering cap in place on the DC, no noise difference.
Pinouts, checked and double checked, they were socketed originally too so I gave them a move around before I soldered them in to check and the LED was turning on and off as it should.
Soldering, got some lovely lead solder still from the 70's, good joints with a needle tip and a razor down the tracks inbetween the copper for good luck.

The pedal worked fine once I swapped it to my last 3PDT with input grounding so that narrows it down to that board, was I right in soldering the positive of that electrolytic straight to the input of the circuit board?
