there seems to be quite the niche market for enthusiasts who make custom amps and sell them with high profit margins. this leads me to some questions…
- do any of them sell their schematics for the DiY’er to try?
- are there any DiY tube amps designs that are open source / royalty free and are they any good?
- these enthusiasts…where are they sourcing the parts? I’ve heard that some of them are quite expensive.
I haven’t seen anything about niche enthusiasts making custom R2R DAC, so if there are, ejumicate me. at the same time, same questions as above. can you buy schematics or are there any good royalty free designs that when done right can challenge what you can buy? I’ll gess you likely get the parts for these from the same places as the amp parts…but if not, where do you go?
