TS-10 Tube Screamer "Switch on Squawk"

[navvid]

Hello All

I modded my TS-10 to bring it to TS-808 spec, and as expected, it now squawks when switched on at high levels. I have read on Analogman's website that he has fixed this problem, but I was not able to find out how. Anybody know how to fix the "squawk"?

Just a pop when switched on, or does the sound continue?

Just a squawk when switched, the sound does not continue. Analogman and the others whose tutorials I used said that this would happen to a TS-10 when modded to 808 spec, which is weird, because the TS-808 did not have the same issue. I think they say the switching fets are different, and maybe this causes it.

In that case, if you're planning to convert to true bypass anyway, which will completely bypass the FET switching circuitry, why even bother with this? The DPDT switch configuration I posted in your other thread generally takes care of any switch-related popping very nicely.

That's true, and I am working on that mod, but it's a little difficult because the TS-10 housing doesn't fit a round panel mount switch. I have read on forums that for this reason, many people rehouse their TS-10's in addition to the 808 conversion. The in/out and power connector's are also pcb mounted and kinda crappy, yet another reason to rehouse it. Me being the stubborn jackass that I am, because the big modder's out there don't offer the true bypass mod for the TS-10, I want to make it work, just to do what they don't. I figured I would replace the 1/4" jacks and 9v connector with sturdier panel mounted ones as well. Probably more trouble than the thing is worth, but it was given to me by an older blues player so I like its mojo and want to hang on to it.

The switchcraft connectors I bought had to be filed down to fit, and I had to order a switch which I am waiting for, so in the mean time I put it together so I could play with it as is until I have properly fit all the parts for the bypass. To remove existing switch, I will likely have to destroy it, making it basically unusable until I work out the switch. And again, as it is, it works, it just squawks. Which isn't that big a deal, but from what I read on Analogman's site, it's probably a simple fix.
