They still come up on ebay from time to time.  The tier 1 tubes are silly money, and over rated IMO.  Buy a Sylvania Gold brand or Valvo 6080, or a Russian 6H13C and your 90% there for $20.

Welcome to my world. Before you talk something up on the Internet make sure you own most of them. When we started Tape Project a Technics RS1500 was worth about $250. A year later you could sell them all day long for $1200. I wasn't smart enough to buy every one I could find before we started.

Compared to many hobbies a tube here and there really isn't to bad. Finding a 60 year old tube that still works and sounds great is also lot of fun for relatively small beer.

I don't want to think about how much the other half spends getting her hair done!

Hi guys,

How does the Chatham 6AS7G sound with the Crack? Also, thinking about getting the Mullard ECC82 Re-issue from Tube Store dot com or the Valvo ECC82 on eBay. Do these two tubes go well together? Your thoughts are much appreciated. Thanks

picked up pair of Bendix 6080WB's, one of them has an audible "tick" sound inside of it that happens every 2-5 seconds (keeps ticking until it cools off after i take it out too) and it's driving me nuts. is it a bad tube? anything that can be done?

oh good and the other one i can't even type on my keyboard without getting microphonics through the right channel.

gotta love ebay.

I have had a brought a few nos graphite plate tubes in the past most have suffered from pops and ticks. I left mine running for a couple of days straight with a old pair of phones I use for testing and they have settle down with running in. I also brought a bunch of used ones from equipment pulls they all tested at nos level and all of them ran nice and quiet.

The ticking sound could be the glass heating up.  On tubes with very thick glass, this can take a long time (an hour or so on 6C33' in my experience).

Yes, it is.  That is a pretty reasonable price as well.

Thanks Paul,

Also,

I've read up on 12BH7's as being superior to 12AU7's. I'd like to try them both to compare the two tubes. Can anyone recommend a good 12BH7 tube? I'm looking at the Vintage CBS 12BH7 Black Plates on eBay right now for around $30. Is this a good deal?

Btw, I have Crack+Speedball and running on HD650's.

Man, I am out of touch. I remember when they were more like $15. Of course I also remember when guys used to drive to my house with truckloads of tubes and ask me to take them.

It appears that the 12BH7 will need to run more current than a 12AU7 to properly bias the output stage in the Crack.

Just bought some Svetlana Winged C 6h13c tubes from Russia on eBay and I'm stunned and amazed.  I have the Chatham 5998 and Western Electric 421A and I think I've just struck gold and at $10 a pop I just don't think anyone can go wrong.  They are a tad brighter than 5598 Chatham and WE421A but I like bright.

I'm buying a stash of these things.

I'm going to somewhat retract this statement.  Left the Crack on all night and started listening again and it sounds flat now. A good tube but not a great tube.  Lots of things are bright and airy when new and then settle in.  This settled in a lot.
