It can cause an oscillation if there are issues with the tube.In your preamp you emailed me about,the biggest issue I had on the Suprateks are broken wire connections on the function switch..Look closely and you may see a solder connection that came loose on the switch..I meant to email you back but I just got back.
You need to do this as well.Go up to the 5881 regulator tubes and see if you have 305vdc in pin 3..If you don't,readjust the pots in the regulator until you get 305vdc.
