Hi, Aksaphiles,
In terms of building time I have taken over six months! When I did not understand something I went out and got a book to explain it all. I was also limited by lack of money to buy things like the toroids, wire etc.
However, I looked at it as a learning journey. Consequently the time meant nothing but the enjoyment and pride I have got out of building my Aksa 55 watt Nirvana and TLP Nirvana has been enormous

. I would encourage all newbies to take this attitude and you will be well rewarded.
I have said this before on the old HD forum but for newbies just starting out, go and get a pack of cheap resistors and a board with stacks of holes in it and solder them all on (they only cost a couple of dollars, peso's, pounds whatever). Secondly, get one of those helping hands thingies, they help enormously.
Thirdly, and most importantly, do not put your coffee cup next to the soldering iron. I still do! And I still get burnt reaching for the cup and getting the iron because I don't look at what I'm reaching for!
I am now building interconnects and power cables (they look great!) and looking forward to more projects. I originally started out trying to save money but I have now found a new interest that is fascinating, fun and really not too expensive. I have alo found, without exception, that everyone I have dealt with has been really helpful, and only too happy to share their their knowledge with me.
Cheers,
Bluesky
