Gauging interest for 600ohm (pultec clone) LCR RIAA modules. Lundahl has 45mH and 1.8 H chokes on catalog and they are selling for 130euro/pair and you need to add a couple capacitors and few resistors. We can also run a short PCB batch to make things prettier and easier to build. I believe a target price would be 300euro/pair but maybe we can work on that if volumes go up.

Note, Dave Slagle Intactaudio/forum is the LCR-guru. He will tailor LCRs to suit anyones needs.
I have a pair of Lundahls and they have below acceptable tolerances. To be of use they need to be matched. They might have solved the problems now as it was a quite a few years since I bought them. I have a source who, anyway earlier, had matced units to sell.
The Tangos I had earlier had extremely tight tolerances.

Jacmusic sells matched LL chokes (3% tolerance) and as far as I know a new model is now available. I know about the many discussions on Dave's forum and i am pretty sure his irons would be' bullett proof but not sure that would be a proper andlarge group buy. I need to recheck what's the story with that 7.5k RIAA he was developing
Hello Gluca,
I guess Jacmusic has some connection with Diyparadiso in Belgium from where I have bought Lundahl. I think Lundahl made the LCRs for Diyparadiso at special order.
Do your really think 3% is good enough? Off course you can optimize with the caps and Rs but I would opt for 1%.

Guys
for 500$ we can buy the set of 4 chokes (80% nickel with taps for fine tuning) from Dave Slagle to build a 7380ohm RIAA. I will order from him. It is a bit more than LL but the higher impedance, the cores, the 2% taps are worth the extra money imho.
I asked if he could offer a special price for the group buy, i will keep you posted

Did you buy the inductors at the end?
What inductors? I had Tango before, and Lundahl now. About Dave, I use his transformers and love them.
About Daves file, please mail it to me. Must check if it is the same I have. I found a pentodedriven(D3a) 7,3k sim yesterday.
