'A High Accuracy Inverse RIAA Network' by Stanley Lipshitz and Walt Jung
http://waltjung.org/PDFs/A_High_Accuracy_Inverse_RIAA_Network.pdf

A great paper if you're interested in designing an IRIAA network, my circuits are based on this design...

how much do you want for it? i got one of those that gib broke, i bet with the two of them i could make a functional one again.. those sound a little brighter than a presto head.. PM me if your serious..

sometimes you dream something, and it appears.. thanks flo..

if such an indispensable tool existed, how did it ever get lost like this, and whats more why are the manufacturers of these tools refusing to produce them?.. it can't be a numbers thing, i can't see a ton of these being sold in the 80's either...

why the sudden interest in listening to stampers?

yes, i know.. but there are no 6800BPS-M or R's around.. but there are 6800EEE's... so maybe make a mother of the stamper you wish to play, or start doing 3 step metal again when the order first comes in..

I figured, but i've never seen yah

and in case anyone wants to know eq points for various curves used before 1964 check this out: http://midimagic.sgc-hosting.com/mixcurve.htm

there are a few 6800EEE's on ebay, if you got mothers to play...

i bet if the coil and spring are strong enough you could cut with this pick up, has a VERY similar design to old presto and RCA heads...

the process is kinna cool, since it's making a pseudo stamper :) reminds me how they split the stamper off the master during the metal process.. never tried it yet, but it definitely should work.. the theory makes sense to me.. just got to make sure the glue will not stick to hard, or chemically rea...

it does help, a lot.. mind if i ask what your cutting system is? if you want amps and preamps (all tube) you should check out tubes4hifi.com, it's a rebirth of the old dynaco stuff.. everything is super affordable for what it is, and superb quality... they keep the prices low by requiring you to ass...

Jay Try looking on this website this page may be of use there are others under schematics http://www.preservationsound.com/?p=1875 you can download the pdf and this circuit will do NAB or whatever you want it to do. I think if memory recalls the RCA curve is mentioned which I believe is the same as...

ok, cool.. i have most of these setting stored in my daw, from using your older plug-in that doesn't compensate.... now to find a tube pEQ, if they even exist..

I use a 6n.. I'm modding it, making it sweet... Technics SP10 motor mounted to the drive shaft of the original platter, so it uses the origibnal body.. the sp10 drives the overhead as well.. CUSTOM vta sp12 tube pre with iriaa and a phono/monitor channel.. vta m-125 mono block amnps.. right now I pl...

mark,

what if you are using a "hardware" iriaa device in the preamp to the amp to the 1-C/D... how would you make this correction in reality, as opposed to virtually?..

I think the head on that overhead is that 1-B that was on fleebay a few weeks ago... Some kids probably bought it thinking he could "ghetto" rig it to that tech12mk2....


just look at the mount for the head, looks non-standard to me, and i believe 6n where NEVER shipped with a 1-B...

I found this on youtube, and figured I'd pass it along... https://www.youtube.com/watch?feature=player_embedded&v=_gyvipBs6Vs some notes I discovered while debunking this method: --Do not use Titebond I !!! It dries crystal hard. --Use Titebond II or Elmers. They dry leathery. --When you peel it you...

I agree..

mark,

have you tried PLA (polylactic acid) as a material?

wow... didn't realize you used "the lathe", do you cut dubs as well? I'd like to hear what that lathe sounds like...
