    I see the tables have turned...i just put down my water before opening this and if i had hesitated for even 2 more seconds, my screen would need wiping. LOL!!...That picture is F'n hilarious!!

    What BH products are you two whining about? Now I'm curious as I've a couple of them also.
    Which ones do you have? I really liked putting together the reduction kit (in integration upgrade....yet) and look forward to the Crack. I really want to put together something else from them but don't want to go too deep down the tube hole.

    I am in countdown for an Eros! Aarons Reduction/Integration upgrade sounds wunnerful here with my diy SUT.

    Man, you got some strange looking cats there! ;) Looks like a shaggy Lemur in a fur coat....lol
    That Eros looks like a fun little kit. I think i like soldering to pcb's better than p2p. Cleaner, faster, easier...

    I've read some extreme exchanges at audio asylum in reagrds to circuit boards/ground plane design and proponents of p2p. They even have books on the subject.

    No doubt, p2p has both a circuit designer and a builder. The builder can make or break the design with poor wiring/routing choices. Just to give props, Aaron is a great builder. Matter of fact I'd use one of his builds without changing anything. His Reduction/Integration is quiet, and I love me a low noise floor.

    Now long ago I built a Coronet 2. One thing common with many builders was a system hum, even with impedance to pre amp respected. My ModWright 70dB MC phono stage was quieter than the Hagerman build. And it was a nice build. I wash my boards after assembly with 99% iso. No flux bridge is going to cause a low level circuit bleed over time. I even used the latest grounding scheme, which was to extend the tranny ground to the star ground.

    So IMO proper p2p can be as quiet as a well designed circuit board. Time wise, you can build these things pretty quick. As you know, they have pictures in the manual which speeds the process versus looking and connecting per a schematic.

    The big issue with a PCB, to me, is that there's really no way to shield a signal carrying trace on a PCB... one may always make twisted pairs of a signal carrying wire and a grounded wire to provide some isolation from hum and noise.

    Shipping date for the Cracks is now up to the 12th! One day to go and mine should be on the way.(hopefully it will ship to the correct address and have all the leads the correct length!)

    Thanks Rich for the props! I think the secret is in the alcohol level during build.

    As a Personal Weather Station Owner PWS (KFLMELBO17) I had to comment on your Budgies shot.

    This is a big problem especially when mounted above your rain bucket.

    That said wish I had gotten in on the Bottlehead Crack deal...love the Sennheiser sound.

    After its winter hiatus this year, our rain gauge has decided it doesn't want to talk to the rest of the system... I've tried various and sundry variations on the myriad "re-establish communications" options sans success. I am going to have to do the nuclear option (factory reset)... but I need to download the weather history info... sometime...

    well...yes - but I cheat. My brother cuts new ones for me from cherry or walnut. I guess my Crack is in oak. This one goes stock. So - I might use some darker stain on it to try and bring out some grain and then at least 4 or more layers of Tung Oil.

    Nice!
    What's the white under the plate at the recess of the wood box?
    Are you going to stick with the stock tubes or do you have ones in mind to immediately swap out?
    What's your SS#?
    Sorry for all the questions :D

    LOL 111-22-3333. You know what's odd...my phone number is 111-222-3333 and my address is 111 222 Street - zip code is 33333...good luck with that!

    This was my brothers first attempt and he cut the recess too deep. That's just some white insulating foam strips to raise it up a bit. Since then I've changed the white out to grey and it's not so obvious.

    The purpose of this Crack is for me to get some stock voltages and wave forms from for comparison to my current Crack that is fairly well modded. The last modds made some definite improvements and I'm curious as to what the original is. Once I'm done with the testing I'm hoping to build what I want to call a BAC - Big **** Crack with a top plate of 10" x 12" so that there is room to stuff all the mods in without stacking them so close.

    Current tubes are a Tung Sol 5998 in place of the 6080 and an RCA 5963 in place of the 12AU7.

    I'll keep the stock tubes in or at least stick with 6080's and 12AU7's for testing.

    Gotcha now!!! Your FICO score is going to tank in the next 3 days. At least i'm giving you a heads up unlike most credit card scammers.

    I'd love to see the pics of your big @ss crack. :D Also, are those tubes that you found on your own or did you grab the idea from the BH forums? Those guys seem to really like only a few different tubes and are quite specific. I've never tube rolled so i need a starting point.

    At this point, my starting point is STOCK!

    @mrbiron Build stock and use the stock tubes. Sometimes you'll get an off balance one but until you listen to stock you don't know how much better (or worse) switching tubes around will be. There are a bunch of 12AU7 variants and some very nice 12AU7's. Just make sure you're using 12AU7 variants and don't use those from the other 12a series (12aT's, 12aX's, etc...). I have some favorites but I will never claim to have heard all of them. Bottlehead has a thread on rolling tubes in the Crack - 79 pages to date. Also recently a review of tubes with graphs here: bottlehead.com/smf/index.php?topic=7853.0

    @voltz Metal Base 7236? Those are nice!

    Video of a recent Crack build - very well done.

    the 7236 is metal base. And It may find a home in the Crack after I try it out with the stock 6080 1st, and I have some Psvane 12au7's & genalex golden lion & Telefunken black diamond.

    I'm hoping he will attempt an Eros enclosure! Not too complicated but I want some artsy arches between the four corners.

    Hows come they ship the tape Eros before the phono Eros? They pro tape? ;)

    Sounds like a real tattoo opportunity there, paisan! ;- )

    As an amusing aside -- some years ago we took a family trip "out west" with my wife's college alumna association (she went to one of them snooty women's college out near a certain Massachusetts mountain from which the school took its name). The tour guide was a woman who, it turned out, was a retired school teacher from Reveah or Meffa or one of the other, similarly quaint and charming suburbs of Bahsten.

    To this day, I cannot see photographs of a certain well known National Park (National Monument) located in Utah without hearing her voice - and accent. That place, of course, is called Aaaaaches National Monument.

    Utah even has it on their license plates!
