Pcgab, what amp will you be driving with the Aksa Lender preamp? The ALPHA 20 has enough gain on board (and an Aksa Lender front end built in) already.
F5/F5T primarily. Maybe vhex when I get around to building it as well.
I'll most likely build two sets of daughterboards, one with less gain, one with 'standard' gain.
I've been listening to the Alpha 20w with my B1 clone in front of it and that combo has been working very well. Source selection, volume control and fantastic fidelity.
Hi Pcgab,
I use a high gain DB set with 12K in R10 for my MoFo and a low gain DB set with 4.7K in R10 for a tube amp that has 20dB of gain and my ALPHA 20. Works out very well 🙂

Perhaps you guys (Vunce and Pcgab) can offer some "subjective" assessments of your preamp to PJN, in the preamp thread?

In case anyone needs miniMELF resistors for the SMT daughterboards, JPs64 has a GB for the resistors in the other thread.

Finally got my parts orders together, still need a few details. Spent a few minutes this afternoon confirming parts, fitment, etc. Hopefully I'll sling some more solder on Sunday.
I got mostly Takman REY for the resistors, and some upgraded caps. I also ordered the RCA's from HifiCollective, I'm really impressed with the quality of these, they are ~$9 USD/each, but they are very well made, and seem quite robust.

Nice parts! Those RCA jacks indeed look very posh and well built. I see JP was designing a high end Preamp.
Good luck on the build. I am about to install the final output MOSFETs on the B.B. running into a high voltage dropout issue on my PSU though. The MUR880 full wave bridge appears to be losing 5v instead of usual 0.6v.
