Ghosting? what if it's not the Filter Caps or Grounding?

    Maybe a noob question:hide but all the threads on ghosting talk about Sprague vs F&T's and changing grounding schemes and other fairly invasive measures.

    Can a less than perfect rectifier tube be a suspect? Is using a silicon replacement (temporarily) a good way to check? It seems that NOS rectifier tubes are recommended in many cases to preserve spec'd voltages, is it a good idea to get a batch and weed out the good ones?

    Thanks,

    Andy

    Hi Rosewood, thanks, already checked, all speakers are fine

    Hi Redman, will try that, thanks

    I have 2 amps with this issue; a 4x 6v6 and a 2x6973 cathode bias

    Make sure your guitar is not producing wolf tones, that is an out-
    of- tune vibration in addition to the picked note.
