I need something for work: the guy next to me has a "tic" cough/ hack, slurps soup every day, and has horrible volume control on phone calls. Its literally driving me nuts! So, do I need 'noise cancelling' (active/passive) or just an isolating closed back? (Edit: updated per post below, and I...

No, not that one. The other one. j/k I didn’t really look at it. I just got the message it was ending soon and stared blankly at my computer screen, questioning reality and the difference between 421A and 7236.

And Bcowen ^^ pretty much nailed the eBay deal...

I just intentionally turned my back on a 421A ending now on eBay. This has to stop! At least for like a week or two... :L3000: Don't I get a chip or something? "My name is Joe and I'm a tuboholic. I just made it 24 hours without buying a lightbulb."

eBay has some arrangement with their favorite sellers. They can get to a point where there's a waiting period before posting a negative review, and they make every effort to make sure you don't leave on. I bought tubes last year from someone who I read all over the 'net was a great seller...

Jesus. I just bought 3 tubes from Fng2u.

That's what I figured. It's hard to know what kind of difference long vs short tubes, angled vs flat or ring vs square getters will make.

Yeah I went with relatively cheap tubes just to try manufacturer’s “flavors”. Once I have combos I like maybe I’ll spring for the best 12AU7. But I made sure to get strong measuring Blackburn and Heerlen made tubes at least.

I don't know what the hell is happening here, I can't stop buying tubes :triportsad: lol I just got IBM/TS 5998 and now have on the way a TS 7236, along with Mullard, Amperex, Philips 12AU7. I really need to upgrade my Crack to better caps, volume pot, etc before buying more tubes but can't...

If you Google the 3213999 number you get a bunch of hits for a Cetron 7236. As above, that tube usually has a metal base in the online photos. I also think the getter looks a little different, but I'm not that familiar with any changes that may have happened. I didn't see where it said Bangy...

I hear you. The 5998 is nice. There aren’t many, I’ve only got one, and I’ve got a lead on a 7236 so I’m wondering if I should buy it.

Hey guys, what about the 7236? Do you like them?

I got this 5998 in the mail today (can’t say thank you enough to who I got it from!). It hasn’t been on long, but... 5998 + Valvo = Holy Schiiiiiiiiiiiitttttttt

Great, you had to make me go look for this. Now this is a thing of beauty! https://cdn11.bigcommerce.com/s-dfccaj35/images/stencil/640w/products/45220/47128/BMISC367_1__82013.1531421623.JPG?c=2
