There‘s plenty information around (here and outside in the web), for all of us beginners -> gurus. Hard part is finding it. (I‘ll post some when I‘m done with my day-job)

I was a noob once. Actually, not too long ago. A bigger noob than now. Building a kit (like the ACA) is a great start, but if you keep on assembling kits you will never learn the stuff you are wondering or asking about. What 6L6 is doing is already amazing. Problem is – these precise instructions (and BOMs) quickly get outdated. Just have a look at the “ACA with Premium Parts” thread and how far this is from the original ACA.

Decide on your next amp and just get started. Ask questions on the relevant thread – that’s why there are discussion threads and members that are willing to help. It's a forum and all the answers are here.

We were all Noobs once.

What you need is to adopt the right attitude and join FAB

-- FEARLESS AMPLIFIER BUILDERS --



(and use 6L6 build guides)

I believe the only thing that could be improved on the forums is a better search function. I read the entire thread and then forget where the bit about bias adjustment is. A better search would make things WAY easier, but sometimes you find other things while going back through. I'm hooked and not giving up, LOL.

I'm usually lost both in space and time

it even happened recently that I did construction (luckily just in simulator) of same amplifier, twice in 10 days (being distracted with 3 different ones in meantime)......

why anyone should be lost in lesser amount than I am?

I learned a lot from this forum and from the articles by Nelson Pass and Michael Rothacher.

In fact, I also learned a lot from LTSpice emulation.

I think it would be very helpful for us if we can download LTSpice emulations of various schematics published here. Most of designers here seem to use LTSpice, but it's rare to find downloadable LTSpice data here for some reasons. Maybe I can't just find them... DO we have ACA or Aleph J emulation?

I once ended up with some parts for some far-out pneumatic stuff when I was sourcing parts for my B1 Mesmerize, and once I had > 1 million resistors. (luckily realized it before buying it )

I usually just add diyaudio after the keywords, then click "More results from www.diyaudio.com".
