Heh..got way too many of those and my tax return just came in..

AM gunning for a coupleof those 12AU7s hard now !

I'm just waiting for my CTH kit to come in from spruce canyon and I'll start building my amp.

I found out that a guy I work with is into ham radio stuff and he said he had a whole bunch of old tubes at his house. Well yesterday I was finally able to get over to his place and sort through one of his boxes and found a bunch of goodies for tube rolling.

13 - 6CG7
17 - 12AT7
5 - 12BH7
7 - 12AU7
6 - 12AX7

The gems of the bunch were 2 mullard 12AU7 and 1 Mullard 12AX7.
They were mostly unboxed of unknown condition, but the price was right, free!
I may need to invest in a tube tester one of these days.
I don't know if the CTH can use a 12AT7, if not they are still useful to me since my SE speaker amp uses a 12AT7 for the input tube. Can the CTH use the 12AX7? the pinout is the same as the 12AU7.

Also one of the 12BH7A has gold pins, the brand logo is pretty worn but it looks like a Realistic Lifetime made in Gt Britain.

holy crap, nice score!!

let's hope most of them are still in good working order, youll have enough tubes to keep you busy for a very long time

 

[sachu]

Wow..taht is one nice haul...you are gonna be good to roll for a while now

Hopefully one of those mullards is a long plate. That gold pin 12BH7A sounds interesting. Make sure the wife bakes this guy a cake or something.

Well if your CTH kit is on the way, you just invested in a pretty good one in my book.

Plug it in. If it sounds good - it's a good tube.

Nice find.

Re the 12AT7 & 12AX7, no they will not work in the CTH, several prototypers tried them with no luck. Even if you could get them to work the gain would be far to high anyway.

I'm listening to David Crosby - If Only I Could Remember My Name ~ Tamilpais High (At About 3) on a 12" 45 through this NOS 6189 from '58 and it sounds pretty fing amazing... Triple mica with black plates and a bit of dust.

maybe i'll get it if i end up getting this amp

Just wanted to say sachu, really appreciate you gathering the russian tubes for us (61NPs) ...a beer awaits if ever you're in Toronto

Btw, interested to hear any impressions on these tubes.

Listening to 6p1n-ev right now. I have four (rocket logos) and have had some stability issues with a couple of them and the e12 circuit, although fine at the moment. They sound quite good. Really nice bass extension. Thick, warmish--maybe a little loss of top treble. I have also noticed that the four seem to have different amounts of gain, if that's possible--although my memory may be suspect on this.

 

[adamus]

wow, complete opposite to the effect of the 6n1ps in the bijou.

 

[tacitapproval]

I should add that this is through HD650s, so my results may skew in that direction.

I will trade you for a pair of RCA black plate 5687's. Telefunken ECC82 Ribbed plate is just as nice if not nicer, easier to find too.
