Wolf; if you’re bored and want to experiment on the cheap you should look at the 7581As. Fantastic tube in my opinion.

I’m a mere five hours into these. This is an alive and kicking tube. It’s like it had a double espresso before the music starts. I’m hearing big and strong delivery, but that’s so overwhelming that I cannot focus on midrange. It’s clear I need some time with these.

Oh Wolf, $45 from a seller I like. Free ship for matched pair at that price, which is cheaper than a night out. https://www.ebay.com/itm/Tung-Sol-Factory-Platinum-Matched-PAIR-NEW-NIB-7581A-7581-6l6-type-tubes-TW... |
as I'm not sure the cryo process is a good idea for tubes but that's maybe just me It's not, all it does is weaken the tube and cause vacuum leakage. When you freeze especially this cold, different materials, they contract at different rates, then expand back at different rates. And in a tube you have glass, high temp plastic or bakelite if nos, metal pins, different metals inside nickel in nos all sorts of different materials. Cheers George |
