Which direction for the BOM?

I forgot something:
Blame Pa
now I can't remember did I post appropriate sketch "how to AVC in Iron Pre SE"
if there is no one and if you need it, just buzz

I was looking for the easy way out. Like a project manager Mouser has. It all goodit's right there, in center of small white circle!!

Easiest way out is to wait for the parts kits to be in the store...
Didn't know, within 2 months???wait for the parts kits
I'm patient but not that patientEasiest way out is to wait for the parts kits to be in the store...
I kinda laugh because I know some folks out there that are waiting years, to have an amplifier built for them. Not my way of thinking that's for sure. For this project, I am just buying some here and there as I can afford it. Reminds of saving pop bottles back in the day to go to the movie on Friday. 2 cents a bottle, and the movie was 35 cents.
Those who wait might wait forever. That's why we are here. I've only put together 2 Pass units, both Alephs. Some need more handholding than others.

Luckily for me ....... Pa's hands are soft, but still guided with Devilish head

Hello IPA-builders,
I would call my IPA-project finished. Listening to it at the moment. Very nice preamp!
Cinemags have been caged (although not necessary). I have started it - I finished it.
Input - switcher and LEDs work properly.

I think you have made them all, right Dirk?
Did you do a comparison and if yes, care to share your observations? 🙂

Hello Robin,
I will report back. I have not listened to the IPA in comparison to many other pres I have built.
What I can say imediately is its 'infatuation' to details and super low noise. It sounds well balanced.
I have built Waynes line stage (and many derivates of the WLS with different active devices), ACP+, KORG B1 NUTUBE, Aleph P1.7,
Son of Zen; BOSOZ and a few others.
All these preamps are more than good! The question is - How good does any of these preamps meet the requirement of the rest of your system?
IPA plays on a very high level - for sure.
Cheers

You have everything to be proud of here. I would like to an in focus shot of the back panel with enough light to make out the details better. Cameras love to expose the lighter background surfaces that are actually not the subject of the photo, making the subject way too dark, or light in some cases. Also, having an LED on will likely skew the exposure in the wrong direction. Just some friendly advice. Your product is very well worthy of being seen how it actually is. I even use a tripod to steady the camera for much better focus. Ok, I will shut up now.
FWIW, I really like that you caged the transformers. I will do the same.

Hello Ixnay,
thanks for the advise. I am not a good photographer.
Have you seen post #2310 in this thread?
