Sorry to post in here.


Does somebody still have the documentation for the drip72 project? Can't find it elsewhere.

What do you need?  I'm still struggling to get the noise down in mine but I do have the manual, etc.

The roll off is due to the caps and resistor in the gain setting part, which form a RC-filter.

Actually that is good. Only -1.5 at 20k. I typically roll of stuff that goes that high depending on what it is. :)

Well, the original goes higher... I wonder why? The Lundahl should probably be better than the 40 year old iron?

I have an unpopulated Drip V72 v2 PCB that I may or may not sell.  I just ordered parts to see if I can successfully do the 55dB mod (bring the gain from 34 to 55).  If successful, I'll keep the 2nd board.  If not, I'll have the board + new parts available.  Will know in a couple weeks.

That would be great. I'm curious what these cost? I guess with Drip he does a single run of every board he designs and that's it?

I think they were around $125 if memory serves.
It used to be a legit company with regular product runs but the customer service is now intermittent at best and straight answers are few and far between.  Really unfortunate that it went south.

That's a shame. I've been getting really excited about done of his boards, particularly this pre. Most diy preamp builds I've seen are 500 series designs and I don't have or need a lunchbox. Can you recommend anything similar to the v72?

There was mention of a different V72 pcb run in the black market here recently.  The V72 is not a complex circuit but is highly recommended.  There's really something special about the sense of depth and the smooth, airy top end response.
