Hey guys. I got a pair of Tungsol/Chatham 6080WAs in. I like it better than what the EL3N + 7236 so far. After going back to the 7236, the treble seemed a little sharp to my ears. The first listen I thought the 7236 + EL3N combo not overly bright and good sounding to my ears, but last night, I think my ears have had too much time with headphones, because it was a little painful to listen to - but again I am pretty sensitive to treble frequencies. I think I should wait until I listen for a few days before I give impressions on these tubes as well, as I don't want to mislead anyone.
Also, a question -- does anyone know what a faded metallic portion overlaying the glass on the top of the tube means? I noticed that most new tubes have the silver metallic deposit completely covering the top portion of the tube. I'm under the impression that it means that it is an old used tube that has been used frequently. I bought these 6080WA's and I think it's possible the Tungsol version that I received may be used and at the end of its' life and just want to make sure... Thanks
Hi r89.
Do your 7236s have many hours on them yet? Are your TS/Chathams used, with many more hours on 'em?...more time should indeed clarify things a bit further...
I used to wonder (worry) about such discolouration of the flashing...until I read that it can in fact be a good sign, in that it has done/is still doing its job of absorbing unwanted gases. My own examples have always been just as 'strong' as those with perfect silvering. My NOS QTL-branded Mullard ECC31 also has a small patch on the glass (inside) above one of the heaters, even though the flashing is actually on the bottom...and it performs brilliantly LOL...
