Yes it looks good but unfortunately it's a crapshoot when compliance spec is not based on a 10Hz test record. At least the European manufacturers follow that spec. The C100Hz x1.5=C10Hz assumption is just a middle of the road necessary number. Depending on many factors it can prove from x1.2 to x2.4 for various cartridges. That would range our calculated example between 8-11Hz.
What C10Hz exactly is can only be revealed by reading a cart+arm system's F on FFT then solving the formula backwards for C via known F and M.
The cover just arrived, so I finished the Ultra.
I'm not really satisfied with the color of the cover, and since I didn't draw the cover in vector cad, there are no marks, so I decided to make a new one with the Salas project mark and draw everything in a vector program.
Stay tuned ;-)

FFT is more secure and precise. Also it doesn't need specific test frequencies because the resonance hill is always there to see even without modulation. Need not even be real time. Can post analyse a needle drop file in Audacity. But yes, a test record is a handy tool for a check.
I suddenly got a good offer for a Hana EH/EL. Anyone have tried it with this RIAA or know if it is any good?
reading along, curious about those Hana's. I hear good things about them.
I currently have a Ortofon 2m bronze under my player at the moment. But was looking at a Hana or Denon 103 as well for a next cart.

Can imagine they favor that one, it is also 3 times the price of the EH/EL ;-) The SH/SL are in between if im right. Didnt even know they had a Umami red and blue. But thats out of my league. I think 500-600,- or so is already more then enough for a cartridge really... But maybe over time my upinion on that will change.
The SL which is as the EL but with longer wearing Shibata stylus, also looks like good value. Light at 5g body mass with enough turns (30Ω) vs a possibly smaller magnet than the ML etc. they should be good at >300Ω loading. They are specified in the 100Hz Japanese way for compliance (10) and they just give an approximate number for 10Hz (16).
Hana ML is worth the expense IMHO. Ultra or FSP, dealers choice. If I came upon a used pickup higher up the line like the red or blue (nut$)... I could be tempted.
My FSP is configured for MM, so I have 2 SUTs to bounce off of that—one with Cinemags and one with Lundahls. The Ultra is... Ultra! It's all good. We also rotate out a Soundsmith Zephyr MIMC Star, and AT33PGT/II, and OC9....I hear good things about several of the lower end ATs, specifically on the SP-10MKII setup we have. It's all very fun....We do keep coming back to the Hana... The rest of the set up downstream of the Salas phono buffet is the DCG3 (more Salas) and ZM's J2 Babelfish monoblocks... into OSMC. De Light Full.

Very interesting. For now my ortofon bronze will do fine for a while. First build my UFSP, then upgrade my speakers and then we will see about a new cartridge perhaps haha. The money tree in my backyard still isnt growing very well.....
About to order all the stuff at mouser. Just to be sure; When using a 2x30v 50VA transformer, the RD/LINK resistor can be just 1ohm right?
There were some 20ohms in my basket, but i think that was from the time i was planning on using two 2x18v transformers.

I got the Hana EL and done some testing with it. With this pickup all work flawlessly and no hum even in the 62dB low MC range. So Salas you where right about the higher gain issue with the combination with the super low 0,07mV output from MC20. But the sound from the Hana ML is not as good as from the Ortofon MC20 mkII. Bass is better from Hana EL but i want to try a better MC. May be the DL-301 II? Or any other suggestions? I dont live far away from the Lundahl transformer factory either, and are temted to get a better general stepup and a suitable pickup for it.
I will do some moret settings and testing with the Hana, but are now spoiled to know better sound quality.

Nice to know that your build is fine and it was all about the cart and SUT adequacy.
I don't trust that the DL-301mkII will make a pronounced difference vs your Hana EL. Maybe in tone but not in real resolution. They're both comparably priced aluminum cantilever elliptical. You have been irreversibly bitten by a cleaner Ortofon LMC classic by now I am afraid. It also has a fine line stylus. Ultimately look for something with boron cantilever and line contact stylus or Shibata, 0.4-0.5mV output.
Meantime adjust your EL cart's geometry including VTA & antiskating in the best way you can. Don't forget to experiment with the input load value. Also allow it some run in time to open up further. Max 50 hours will do that. Don't invest further in step up transformers IMHO. Maybe also try sell the super low output Ortofon and its matching vintage super high gain transformer to have more budget towards a newly built healthy output >1k€ cart connecting directly.
Even try that special low MM gain modification I devised for you before deciding on the fate of the Ortofon set. This mod will not eliminate but will reduce the set's excess and hum pick up by a good 6dB.

Thanks Salas. Always helpful. I will try all suggestions. But at the same time I want some advice in real carts suggestions too. To be able to pick good stuff on occasion.
