Default LF 41Hz AMP10 Basic assembly instructions

Hi all

I ordered and received an AMP10BASIC (41Hz Audio:AMP10-BASIC kit) from 41Hz Audio. It arrived in good time, but the forums are STILL down and I can't access the build instructions.

Several emails to the store owner have gone unanswered (but that seems to be the norm having done some searching).

Can anybody help out with instructions? I'm not confident enough to solder it based solely on the schematic.

Many thanks!

Here You go.
I strongly suggest You modify the 5V according to the included circuit.
Also change c60 to a larger value (I used 470uF) and I recommend You use a input gain of 1.0 (22K for R3, R4, R43 & R44).
Good luck with Your build!

You're welcome

The reason for increasing c60 is to avoid turn-on "pops".

Replacing R100 with the above circuit avoids turn-off "pops" and gives a better regulated 5V.

Hey xrayspex: do you happen to have the assembly instructions for the regular Amp10 or Amp32 ? REALLY wish I'd copied those from the main page when I bought the amps last year...

Sorry, nope.
Hope Jan gets the 41Hz-forum online again soon...

Okay, well thanks anyway. The Amp10B ai you sent will give me something to work from for Amp10 so it's certainly better than nothing.

Yeah, I'm starting to wonder if the 41hz site will ever go back online...

Alrighty, am almost done with the board stuffing, just a few of the larger caps and 2 resistors to go.

The assembly instructions say 47k for R43 and R44 if using a passive volume pot (which is what I'm doing). However, the kit came with 56k resistors for these locations. Will they still be okay?

Personally I think you should aim for a lower input-gain since this amps input-protection is very sensitive. In my experience -1.0 is perfect even with a passive volume-pot. The chip-manufacturer recommends 20K/20K.

Alright, almost time to power up

However, there are no polarity indicators on the PCB for the power wiring, nor do the instructions mention it. Any advice?
