Well, it looks like I wrote my last message a few days too soon. After over 2 weeks of static-free operation, my Two-stroke started up again with the static noise again yesterday.

At one point, the static became so pronounced and sustained, that it continued even after I turned the volume knob to zero (this is not typically the case -…[Read more]

Just a short follow up to an old discussion. The static noise that Robin helped me eliminate eventually returned, and I decided to replace the power and rectifier tube sockets. The socket for the pre-amp tube fits quite snugly, but the power and rectifier tubes seemed somewhat loose in the original sockets.

Thanks again to everyone here, and especially to Robin, for spending some of his Sunday troubleshooting the static with me. His work looks (and sounds) even better in person than it does here on the site!

Thanks to Robin’s help, I think the noise has been located and eliminated. It seems that it was a poor connection in the socket of pin 8 on the power tube. Tightening that socket “clip” seems to have taken care of the strange static. Apparently my previous efforts to tighten up those sockets were not sufficient.

I do have a 68Kohm resistor between the jack tip and pin 2 of the 12ax7.

Tonight I put together an “audio probe” as per the instructions on the billmaudio site (thanks Robin for the suggestion!):

The boost switch does not have any effect on the noise. I grounded the volume pot to itself (back of the pot can), and the ground tab on the tone pot is connected to the back of the can by way of the .0047 uF capacitor as shown in the chassis layout diagram. The nuts holding the pots on are screwed down pretty tight, so I think…[Read more]

Now that you point out how the circuit is wired, it totally makes sense that I can’t get a proper reading of that resistor value while it it soldered in place – thanks for pointing that out.

Thanks Robin for the suggestion. Just to be sure I’m pointed in the right direction, the feedback loop you are talking about is the 68Kohm resistor between the speaker output jack and pin 8 of the preamp tube, correct?

Yes – if I touch the guitar strings, the noise stops.

If I don’t touch the guitar strings, the noise eventually fades out – sometimes within a couple of seconds, but sometimes it will persist for much longer (on the order of 20 seconds or more – by that point, I’ve usually touched something on the guitar or amp that stops the…[Read more]
