Question about my 12AY7?
Re: EH pre racked
Hey McKay,
Would the innards of the 12AY7 have worked in a 2U enclosure, or is it simply too big to fit in a smaller enclosure? I'd like to rack my two 12AY7s up, but I don't have 4U of space to spare in my rack. Also, I don't know how hard it would be, but if you ever find yourself with some free time, I'd love to see how you handled the back and the inside of the rack.
Thanks for posting that pic!

I left room on the other side for another pre or a compressor. I bought the rack case at a thrift store for $10 (was a video relay before). I bought the knobs at an electronics store. I'll post some pics of the inside next with the ribbon cable extension I put in...I used the pre this past weekend on a drum session with a band. I used the EH on one of the room mics...
Cheers...

Actually yeah. I've noticed this too, but only in one instance. When I use my Oktava MKL 2500 (tube mic) with the 12AY7 on a distorted electric, or cranked treble amp. I thought it was pretty strange too, but couldn't duplicate it with any other mics. For a few things I tried it on, I liked it. For others it wasn't that cool. As soon as I swap out the preamp, or mic itself the wierd fuzz goes away. I would explain it the same as you, sounds like a wierd clipping, but the overload light does not light. Only with the MKL 2500 though and only on electric guitar.?buschfsu wrote:ok ive tried various mics tubes etc. it seems that mine does have some noisy pots and i cant go past 10 oclock without getting a fuzz that i would call subtle but not musical. its almost like a clipping at the transients but the overload light is not on. anyone else?
Have you tried another mic? Maybe this is just truly showing the lower(ed) headroom of some of our microphones?
Although I don't have much to offer regarding an answer, I just wanted to let you know you weren't the only one.

slowly panning across something kind of crappy...
I noticed the same thing on mine last night recording mandolin. To me it sounds more like a fizz and I particularly noticed it on the low notes. I had also noticed it on bass but thought it was my crappy bass setup. I checked the mics on my martin and noticed it was there too. Fizzing like a can of soda pop. I tried a couple of different crappy mics-the 603s and kel 1 and they all did it. All my condensers also have the problem where the power light goes dim. I'm bummed- I was loving this thing but now wish I had bitten the bullet and gotten a hamptone kit. Woulda been halfway there for what I spent on this.nlmd311 wrote:Actually yeah.

Wanted to avoid starting yet another thread on this... I've got an SCA complete kit coming and will have room in the SCA chassis and was thinking about using some of the open space to mount my EH 12AY7, then get fancy and use front panel express to fabricate a new face for the whole thing.
I'm good with soldering cables, patchbays, etc. - the easy stuff, but my question is with the EH 12AY7 -- does this thing need to be discharged or do I need to worry about the voltage or anything like that? I'd like to stay alive past this project and if I have to leave the EH out to stick to that plan, I will.
Thanks.

Anyone have any insight on whether or not this must be discharged? Thanks.
