content: I came across this projecthttp://www.hpmemory.org/news/barney_ampl/barney_page_00.htmby the founder and director of Hewlett Packard (HP) laboratorieshttp://en.wikipedia.org/wiki/Bernard_M._Oliver.One of the interesting things is that the documentation is said to be at the level that was supplied with HP test equipment of the time. Circuits are included. The manual is amazing (I thought)http://www.hparchive.com/Manuals/Barney_Oliver_Amplifier_Manual.pdf.I did a quick search on this site and couldn't find anything about this - thought it might be interesting to someone. (The article that I saw that mentioned this amplifier washttp://www.mondaynote.com/2013/12/02/sound-holiday-thoughts/).These amps were only to be sold to HP staff members, there was no warranty as any repairs were expected to be done by the owners, which is understandable I guess. They were also designed specifically to suit a certain model of speaker and of phono cartridge.Perhaps an excellent tear down candidate (however I imagine quite hard to procure).

content: @c4757pI had to look up Rule no 34 on the urban dictionary to understand what you were getting at.And yes, I concur.For others, like me, who are not urban lingo savvyhttp://www.urbandictionary.com/define.php?term=Rule%2034@c4757pPS : I never really understood the reference to your screen name,The best I can come up with is a pair of BC547 and BC557.If you dont mind my asking, what does it stand for?

content: I'm pretty introverted in real life. Quite happy being known as 'c4757p' (it being unpronounceable in real life is just a bonus) and looking like a yellow octagon labeled Praseodymium. (Do I even know what praseodymium is? Not a chance.)Quote from: envisionelec on December 13, 2013, 02:42:18 amNowI'm frightened. I used to be a lot more active on the Internet when I was a high school student. Oh god, ahigh school student.
