    • Lamm Industries LP-1 Signature Phono
    The LP1 Signature is a vacuum tube preamplifier that employs a high current pure class A operation from input to output.  No loop feedback is employed.  Other features include:
    • Audibly neutral power supplies (one for each channel) featuring full-wave vacuum rectifiers, choke contained filters, vacuum tube high-voltage regulators, and solid-state low-voltage analogue non-switching regulators used as the heater supplies
    • Three separate inputs for MM and MC (two inputs) cartridges
    • All amplification stages utilize high transconductance super low noise high-current vacuum triodes
    • Very accurate RIAA EQ network

    Each preamplifier is carefully handcrafted of the finest materials and hand selected top quality parts like military-grade DALE metal-film resistors, RCD wire-wound resistors, BOURNS multi-turn potentiometers; ELECTROCUBE, CORNELL DUBILIER and ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER electrolytic capacitors; HAMMOND chokes; gold-plated NEUTRIC connectors; and military-grade low-noise long-life vacuum tubes.

    A custom-designed massive damping panel installed in the preamplifier unit significantly reduces all types of mechanical vibrations which, in turn, leads to a more extended, coherent and natural bass reproduction.
    The LP1 Signature features a custom-designed super-low noise power transformer.

Christian,

My dealer called me to say Graham Elite will be delivered next week! Hope it is true, it has been a long wait.

number_95

Rocketman,
Yep, the 300b tubes lack a position key that locks the tube in the socket. So you do need to observe the thin and thick pins. I mistakenly did this myself and once was enough.
Charles,

H5000 PS repair update:
I heard back from David Beetles. Apparently my diode install was not thee problem. I re-installed the 300B's backwards. I can't stand the pins on them as they are easy to mis-orient. Another lesson learned.

Hi Mribob,

I tried the RCA bullets first. I use them for my tonearm cable into my phono pre. It sounds better with them than without. There is a considerable breakin period required. When I was not listening, I played a cd on repeat through them 24/7 for about a week. The effect is hard to describe. It is really about coherence. The music flows with greater ease and the bass region seems more integrated. The same type of effect occurs with the speaker bullets. They still have a ways to go before they are fully broken in. The best way to hear their effect is to use them for awhile then pull them out. I have not pulled the speaker bullets out yet to see what things sounded like before them. I plan to do so in another week or so and will post my impressions.

rockitman

Any new impressions on the Bybee bullets? Have been curious about them, not sure how they work, or what they help fix.
Nice system by the way....very well thought out and true example do what is possible.

Not yet. I am hoping soon.

rockitman

Hi Christian, have you received your Elite tonearm? I still wait for mine to get delivered. I have no idea why it takes so long?

Currently under audition are Bybee Super Effect Interconnect/Phono Bullets. I have to admit that I was skeptical. While they will need some significant burn in, what I am hearing so far is startling. There is a significant increase in bass to midrange coherence, better defined bass and an increase in extension. The sound stage width and depth has significantly grown. I am using these out of my Allnic HA3000 moving coil headamp. I wanted to try them with my moving coil inputs on the Allnic H5000 phono, but since the rca's are recessed into the back plate, the rca male does not make adequate contact since the tube after the rca is too wide. I am going to see if they can add 1/4" in length to the rca diameter tube. Based on my audition so far, I may be trying the speaker bullets.

Well I think I found my favorite tube. Mullard late 60's O getter, brown base GZ37's. Maybe it has to do with the higher current. You need to have the upgraded heavy duty diodes installed. Something I botched on my last unit. I made the cardinal sin...soldering iron not hot enough and I overheated thee circuit. With these tubes the sound erupts and expands with a voracity I have not heard with this unit before. Everything is more extended, tighter and more dynamic. I now prefer transformer input to head amp/MM input. Rectifier tubes make all the difference.

rockitman

Thank you, I also ordered a 9 inch Elite, hope it get delivered within similar time period you mentioned. I hope the differences between Elite and my Phantom B-44 will be audible. If this is the case, either I will upgrade B-44 to Elite as a second tonearm or will go to a different route like Ikeda IT-407 12" tonearm.

#99,

It will be a few more weeks. No specs. I would imagine they will be very similar to the Supreme, although the Elite arm tube is of a bigger diameter, different wiring and the bearing is also improved. That is all I know.

rockitman

Hello Christian,

When do you get your Graham Phantom Elite tonearm delivered? Do you have the specs for the new Elite?

Regards.

number_95

Outstanding service.

Hi Christian,

That's great news. Allnic is a first class company both with its superb products and great customer service.

Allnic service:

All I can say is unbelievable. I screwed up my unit (mistake of a too cool soldering iron)and they are sending me out a new power supply immediately with the new heavy duty diodes already installed. Once I verify all is well, I will simply return my broken unit. I am much happier now as I will have it by end of week, versus a few weeks waiting for repair. Allnic takes great care of their customers.

WARNING!!!!!!!!!
Change diodes at your own risk. I seemingly de-soldered the stock diodes and soldered in the heavy duty diodes. All seemed well until I reassembled the unit. During reassembly, my finger touched something in the circuitry and shocked the hell out of me. The unit had been unplugged for an hour. My finger was even blistered. So I plug the unit in and the meter on the left channel doesn't even light up. The right channel did light up, but the meter was far to the right. Perhaps the meters need to be re-calibrated for the heavy duty diodes ? In any event it appears the unit needs to go in for repair. Damn !!! I received my GZ37 tubes today, so that motivated me to put in the new diodes so I could check GZ37's out. Back to the Pass XP-25...Damn again. :-(

So I tried NOS late 50's Phillips/Holland made GZ32 big bottle (shape of 300B)rectifiers last night. They have a spacious sound, but are a bit loose on the bass definition. I like the GZ34 F31 Valvo's and F32 Mullards better. The best tube so far is still the German made Tele's (Navy Tubes)from the late 60's with a bottle similar in shape to a GZ34 but is about 1/4" bigger in diameter. It also uses the full octet of 8 pins instead of the usual 5. I suspect the 3 additional pins are dummies and are there to secure the tube in the socket better than the 5 pin. Next week I should get my Mullard GZ37's to try. That will be the end of the rectifier tube test odyssey for this phono pre.

rockitman

Rockitman, at 400v my amp relaxes and sounds a bit more groovy. It sort of breathes more naturally and the leading edges are softer. At 425v, the amp sounds a bit tighter and has a bit more jump and sounds more dynamic. I may have more to report on this subject now that my EML 300bXLS are fully broken in. I havent tried my GZ37s with the EML's yet.

jetrexpro

Owner
Thanks for pointing out the difference in operating voltages Jet. I am not sure what it all means as it relates to change in sound. I need a crash course on electronic circuits.

rockitman

Totally with you on rectifiers. In my system GZ34 yield a B+ of 425 or 430 and GZ37s give a B+ of around 400v. Very different operating points for not just the output tubes but also the driver tube. I like both for the different presenations they offer. Have not rolled in the 37's for some time. Time to do that. I have also found a fairly easy way to reduce the B+ of my phono stage by 15v which also offers interesting results.
Regards Jet.

jetrexpro

Owner
These may be a game changer. First listening session very positive. The bass & midrange seem much stronger, more slam, bolder than any GZ34 I have tried. It almost sounds like I added a well integrated sub. Get them while there hot.
http://www.ebay.com/itm/Telefunken-GZ32-5V4G-CV593-NOS-late-60ies-super-rare-German-Navy-tubes-/201041212057?pt=Vintage_Electronics_R2&hash=item2ecefd7299

I have come to the conclusion that I will probably never settle on a favorite rectifier, although this may be it. It is nice to have the option of such different sound presentations by rolling these tubes. Perhaps GZ37 will be even better ? I plan to solder in the new heavy duty resistors to handle GZ37 current this weekend, just in time for their arrival (Mullards) next week.

The GZ32 Telefunken small bottles arrived today. I also have 1950's big bottle GZ32 tele's made in Holland. First up is the small bottle german made tele's. They are warming up now. :-)

Email sent Albert. Thanks.

rockitman

Christian, I'm already working on that.

KS and David have an idea that they think will provide the flexibility you want without sacrificing performance. They ask if you would provide a diagram showing your EQ interface pathway (along with equipment model and description).

Please send to my email address.
