Audio Note Amplifier Kits

@johnah5 - I own a lot of bikes (I own an e-commerce cycling business), but the one in the photo is one of my oldest - a Serotta ti with S&S couplers, SRAM red etap. This is the one I usually take to Europe since it fits in a small 24"x24"x10" case so it's easy to travel with. 

Audigon seems to have a lot of bugs with their website. Here's a direct link to my system page - jaytor's system. You can try in incognito mode if a direct click doesn't work. It works fine for me, but I've run into lots of quirky problems on this site.

I don't have any experience with the Bottlehead kits, but they look pretty nice and I've heard a lot of good feedback on them. 

I'm in Portland, OR, so a long way from Indy. But if you ever get out to Portland, I'm always happy to show off my system 😁

Thank you for the invite!  I started reading your thread and love the idea of upgrading a kit but was lost quickly. 

I just got a Frame from Independent Fabrication in steel that I built up.  I have a Giant TCR with the integrated seat post that weighs in at 16.5lbs in size XL with pedals attached. IN is perfect for biking in the wind.  The always blowing as a headwind no matter how you turn flat hot.....anyway.

Nice bikes. IF makes an excellent steel frame. I don't own any steel frame bikes at the moment - mostly high-end carbon road race bikes and a couple gravel bikes. I've got to pare down my stable at some point. 

Here's a decent book to start with. It introduces basic electronics concepts before going into vacuum tube amp info. 

Vacuum Tube Amplifier Basics by EJ Jurich

A more advanced book that covers vacuum tube amps in much greater detail is

Valve Amplifiers by Morgan Jones

This one requires a bit more basic electronics understanding though, and has a lot more detail than you will probably ever need. It's also several times the price of the first one I listed. 

Moots Routt 45 for a bike here 😁

More relevant to this thread, I built an AN Kits EL34 integrated amp a few years back. Great amp and I am still using it. I got the version with the upgraded C core transformers. I love the sound of this amp. The kit was well thought out with good documentation for the build process. I changed out the binding posts for some pure copper Cardas ones, but the supplied Audio Note ones are pretty good quality as well. I happened to have the Cardas ones left from a different project.

I previously owned an Audio Note P3 300B amp and loved it but never got to compare it to one of the ANK versions.

I wouldn't hesitate to go with Audio Note Kits again.

@davej  thank you for the positive feed back on the ANK products. I have built two amps from schematics and I sourced all of the parts. The first was a JE Labs 2A3 and the second Gordon Rankins Bugle 45. I had fun building both of the amps. I want to save a step and get everything required in one box at the same time.
