6AS7 getting rare? - Page 2

thevoice · 12th November 2009, 12:54 AM

Judging by how often I've found them in people's junk boxes for next to no money, they are certainly not getting expensive or rare.

You're lucky... I had 6 from a power supply, tested matched (all 12 sections), had them as a lot of 6 for $1.99 and they never sold in three relistings.

Ended up getting more by trading them for sockets in stuff with forum members.

I have collected about 50 or 75 of them over the years. I tried to Ebay some of the known good ones a year or so ago. Same results, no bids.

I seperated them into 2 batches. Those that are cosmetically OK, and those that are ugly, or have loose bases. Of course I have more ugly ones than pretty ones, so there will be some "tube testing" experiments on some of the ugly ones at a later date.

20 some years ago I managed to generate a controlled plasma ball inside a 6AS7. This used up all of the vacuum in the tube and when I got the tube hot enough to melt the glass, it bulged outward indicating a positive pressure inside the tube! I lost that example long ago, but I now have a power supply big enough to repeat the experiment, and I still remember the technique.

Didn't look to closely.
They were out of America - which is very economical at the moment what with the economy been in the toilet.
I like Winged C 6H10's (I think thats the number), very smooth.

Europa Ebay, about 14 euro

I have tried Mullard 6080's and they were the brightest of the lot.
I have tried RCA 6080's and they were clean deep and detailed - very good.
I have tried the Winged C 6H13 and they had that lovely smooth sound with strong deep and detailed bass response. and they are in the lovely ST bottle.
For me the 6H13 wins on all counts for my system.

6H13C is good

looking at some resources from Russian sellers thread , they can be found even cheaper than 14 EGreenies

Hmmm, sounds worth checking out. Thanks guys!

But 14 euros is like... $750 CAD

Cheers!
