DIY Amp Preamp building


I just popped on a Dodd Audio preamp . He is a one man operation . From reviews his preamp is comparable to really expensive gear for a fraction of the price . It makes me wonder about what's inside all the gear i have owned/own. What am i paying for . How much is going to the marketing ,dealers,ect... .Anyone in MN build tube amps ? If so let's talk about building me one .

DIY means Do It Yourself, not "building me one".

You can get kits like Transcendant and Bottlehead and start to learn what you're paying for, except for design, which is significant and costly.

Ralph, is Atmasphere still offering kits?
I believe the M-60 is available as a kit again. Other sources for kits are Hagerman and K&K Audio.
