Tube and Tube Socket Cleaning

Yes, it did change sides. However, I thought that maybe this one tube was exposing a problem my pre-amp was experiencing on both sides. The pre-amp (CJ PV10A)is about 10 years old so it (really, really) needs to be cleaned up anyway. The tubes I installed are new.

Thanks, all!!!!

most-likely caps become to be statically noisy and need to be replaced especially ones in ground isolation circuitry.
measuring capacitors for the face value +-tolerance isn't an easy task and require havin an osciloscope to measure the discharge time so without any checking and suffering setting up an oscilloscope for the right scale just change them all by face value and with better quality.
checking low-wattage bias resistors is much easier task for the rated value.
fuses within such period of time even if functional can create an extra noise.
whenever you change the caps you should run your preamp(approx 1 hr) on no-signal operation meaning that you will have an input connected with muted or unpowered source.

Brad, as Greg suggests, sandpaper will do very well, because you can fit it round the prong. I don't see any harm in using a nailfile though. I've both used the metal and the wooden ones- gentil and carefully though, just enough to take away the oxidation. Don't know where you can get Kontak in Atlanta. You could try Audio Advisor via mailorder. Craig Pro Gold probably also from them or directly from the Craig webside. (Am not sure now, if it is CAIG or CRAIG ) Cheers,
