6922 Issues / Recommendations

I have a pair of Quicksilver Mid-Monos. After shutdown one of the amps produce a static noise through the speaker. Last night while shutting down in the dark I noticed some arcing inside the 6922 driver tube. I am assuming that this is the source of my problem.

My output tube are EH-KT88 and are about one year old. Based on past experience these tubes tend to last 2 years. The 6922 are the originals that came with the amp when I bought them new more than 4 years ago, they are Sovtek.

I guess I should swap tubes between amps to be sure to find the culprit. One more note, the amps play fine when on the problem only occurs after shutting off the power.

If my assumption is correct and I need to replace the 6922, what tubes do you recommend. Budget would be up to 100$.

Hi Nick_Sr

I would contact the tube seller Jim McShane asap for help. The guy great with tube recommendations for gear. He handles new and old stock tubes. He's help me a bunch with preamp and power tubes for my gear.

If you can find them try Ediswan 6922 tubes from Upscale Audio. When I had a 6922 based tube preamp these Ediswan 6922 tubes added some nice sparkle and detail in the mids and highs in my system.
