Greetings,
Progress has been slow but thought I'd post the kit build so far. What is opinion of build quality?
(please see image attached)
The solder joints are "known" good; been doing that for 40+ years now.
It's a whole lot of fun to build and I'm taking my time enjoying it.
Sometimes taking 2 or 3 minutes to route a wire properly. :-)
One thing I'd suggest adding to the manual is checking the fine / coarse attenuators with
an Ohm meter. I did so after completion of that phase of the kit and know they are wired
fine.
Small error in the manual, page 45, 3'rd paragraph says to solder at C socket but one
should NOT. Building a stereo amp makes life easier since your doing task twice only,
in mirrored.
One thing I find to help is to cut and strip several pieces of wire (4) then continue building.
Seems to go much smoother this was. I also review the instructions for the sub-section
so I see where it's going.

FWIW, I think it looks superb so far...

That is nice, neat work. It looks like you are doing what I did with my Eros build. I did 15-20 minutes of work a night and made it as tidy as possible. My Foreplay and Seduction were not as pretty.

Nice work, It look Great!

Looks great, keep up the good work Tim! :)

Thanks everyone for the encouraging words! Really appreciate it.
I added some more wires and put the PWB's on their standoffs so the kit looks more complete than it actually is.
It took about 25 minutes to install 7 wires. Not a particularly fast pace.
Thanks again,

That sounds like the perfect pace to me!
(You're actually pretty close to completion, based on your pace, I'd say ~2 hours)

Nothing wrong with taking your time ;D I always check and double check my builds, much better to be certain that all steps are correct than rush through a build and then have no idea why it's not working.

If only all the cords behind my system were as neat!

The Mainline build is completed. The amp is super quiet, can't hear any noise.
Touching L/R input channel results in the expected 60 cycle noise in the L/R output channel.
A real stupid question.... Can one interface a low output (2 or 5 mvolt) turntable direct or is a phono preamp required?
Thanks

A phono preamp is required.

(Good job completing the build!)

Hi Paul,
Thanks for the confirm, I was sure one was needed. I have a Welborne Labs phono pre-amp for this.
With so many cables the system will be a bit of a mess as 4krow eludes to.
The build was very straight-forward. One just has to pay close attention, read ahead a bit and quit when tired.
Posting some quick shots of the top / bottom of the chassis plate:
Best Regards,
Tim

Wow, what a CLEAN design... beautifully done... I gotta have one...
