Always thought that it was the pins making contact with the sockets.
No that's the cause of crackling and static, eroded pins, hum comes from 6SN7 tubes, usually on the left side. I had one tube with hum go away in 4 hours, others after 48 and the longest a week later. All part of the fun with the Darkvoice. Slam in some nice tubes and you get rewarded though! All mentioned on the Original Post of this thread..Always thought that it was the pins making contact with the sockets.
Kinda just mentioned that above..Hum is normal in other otl amps I've tried - it's an indication that your tube is in fact, genuine new old stock and hasn't been used. If the hum stays - that's another thing entirely!
Thanks for the tip, as some NOS 6SN7's are fetching crazy prices now. I lucked out on a 1954 Sylvania 6SN7GTA chrome top recently to pair with an RCA 6AS7 (black plates). Any power tube recommendations for the 6c8g's?Also worth noting, the 6f8g adapter will also work with a 6c8g. These tubes are even cheaper. Look for the national union JAN version (I just picked up a NOS for $15 shipped that sounds better than the NU grey glass in my photo above that cost me $70 for NOS). Another great 6c8g is the RCA round plates (also just got that NOS for $20 shipped).
I'm so tempted with the 7236, rave reviews from everyone here so far. And congrats on the HD6XX.I snagged a chrome top sylvania off ebay for 8 bucks that sounds freakin amazing. Paired it with a ge 6as7ga that was 15 shipped. Such a good combo. I dont know if its a chrome dome or not. The chrome top almost reaches the bottom on one side, very uneven chrome job on it. What ever it is, it was a steal. Its by far my best sounding 6sn7. i also got a phillips jan 6080wc and a tung sol 7236 coming in. My HD6xx will be here monday. So much fun these tube amps are.

I got my 7236 for 30 bucks. Date code is worn off on the 6sn7. It is a gt and it’s has the same vintage 50’s writing on it
