I received my replacement ZDT Jr, and it has a hum/static in one channel. I switched the smaller/front tubes around and the noise switched to the other channel. So I think I have a bad tube. I want to replace it but I don't know which tubes are compatible. I think the smaller tubes are the 66Z1P, which seem hard to find. Does anyone know where I can purchase replacement 66Z1P tubes or their equivalent?

Analogues very much: 6J1 (China), E95F, EF95, EF905, 6F32 "Tesla", 6AK5(WA), 5654 (USA), 6096, DP61, PM05, M8100 These tubes are very common. Often have a low price. EBay may have a name: 6Z1P 6ZH1P 6J1P

I recommend trying to find a matched pair of non Russian 5654. If you read this thread that's what they recommend and though the Russian tubes are not bad I find better quality tubes make a difference. "Yeah, get rid of those Russian tubes. Some are gems, but most of them suck, i.e. dry aggressive and dull." https://www.superbestaudiofriends.org/index.php?threads/massdrop-x-eddie-current-zdt-jr-official-thread.5408/page-5

Try places like thetubestore or tubedepot, they are reliable and have various selections for different tube types.
