Gentlemen,
I am hoping someone can shed some light on my issues, the primary one being distortion and some "frying egg" noise. The distortion is more pronounced on lower notes especially with multiple notes played together. This occurs only when reverb is on. All tubes are fine as tested in another PR 40 and I replaced the RCA cable from necklace to amp. Two other minor issues, the reverb is switchable using the chorale/tremolo switch. The console is outfitted with the Trek II SS1 preamp if I remember the model correctly, the Trek folks asked me some questions then said it was a very early model, and lastly, the bass isn't as strong as on my other PR 40. Tomorrow, with assistance I will try to confirm both 15"s are working. In summary the unit plays clean with reverb off but gets ugly when the reverb is on.
Thank You one and all,
?John
