Hi Nelson

Such lovely work thank you so much... I have just one concern. Your chosen resistor values are from the E48 / E96 series which is a somewhat uncommon range in South Africa. (values as 332 Ohm and 33200 Ohm in the design) I remember hunting for these series resistors 20+ years ago and nobody had them in South Africa, still today they are not easy to find here and they are not well stocked.. with 48 and 96 values per decade, when found just popular values are kept. I have been surprised on occasion in the last few years when requesting E24 ranges, to be given an E96 range component, however somewhat of a needle in a haystack finding the values one needs. (Thick film SMD seems common, maybe even leadless face, but thin film lead that we need here is going to be a challenge to find) Most common are the E24 series with 24 values per decade.

Do you possibly have a version of the circuit using the E24 range which is well stocked in SA and easy to get anywhere here should we need to stuff the board ? I tried looking through the 85+ pages in the DiyAudio thread but may have missed any substitution guide for the resistors. This would also allow the use of carbon film instead of metal film for those who love carbons.

Ps..I know that I can easily build a series combination of E24 components to make up the value needed, I did that 20 years ago, hoping to avoid doing that if possible.

Thank you once again for your contribution to the Audio world.
Marantz123.

I have access to a lot of components, and if not specific values, I do have excellent skills in making very elegant bodges - and have the tools for perfect matching. If you can't manage to get any, let me know. I can send you some over with letterpost 🙂

Do not worry too much. IMHO in this case 332 and 330 are equivalent. The 2 Ohms are well below 1% for a 332 Ohm, or 330 Ohm resistor.
But if I was into RIAA correction networks I would be more careful.

I haven't published the latest circuit, but most of these are ball park numbers.
Just use something similar. Only one to try to get right is the 221 (or 220) ohm
Drain resistor - the distortion calibration voltage is only accurate for this value.

Will this new Zen H2 circuit allow adjustment of the amount of 2H? 0.5%, 1.0%, 1.5%? Will phase be adjustable from positive to negative 2H?
I would like to build a balanced version to restore the 2H in so many DIY preamps which I build in balanced versions. The balanced BA2018 nulls 2H and is predominantly 3H, I would like to restore that aspect of the preamp, if possible.
