How to Put Subminis on Board, Plus PCB Software
Posted: 13 May 2011, 15:35
I'm building a "Powerman" amp with 2 6021 subminiature tubes. I need advice on fastening it to the board.
I've read that people use op amp sockets for this, because the fancy sockets that are made for submini tubes are expensive. I got some op amp sockets, and the leads from the tubes will go in, but they don't seem very tight. Is this a stupid idea? Is there a better way to attach the tubes, apart from blowing a wad of loot on special sockets?
If possible, I would like them attached in a way that won't require soldering when they need to be replaced.
Also, if anyone has advice on cheap (or free) PCB layout software, I would like to know about it. I have the old free versions of Multisim and Ultiboard, but it looks like they won't do a whole lot unless you spend thousands on the full versions. I installed PCB Artist, but it's so counterintuitive, I can't make any sense of it.
I'm considering making an eyelet board instead, like the guy who designed the amp: http://www.harmonicappliances.com/power ... erman.html
