I've got my Szekeres amplifier on breadboard right now. It's the standard configuration except that I do not have the diodes in place. C2 is 2200uF. R3 is about 500k. I am using Rg = 220 with the leads of the resistor right next to the gate. The amplifier sounds fine for just over one minute...

I'm working on the Szekeres amp right now and I'm trying to determine a good guess for how much resistance I should dial in for R3 so that Vds is half my power supply voltage. To do this, I figured I could dust off the circuits book I never thought I'd use and plug in some values for the DC...

I have mild tinnitus that, under normal circumstances where I haven't abused my ears, I cannot hear unless it is very quiet. If you have a similar malady and use Etymotic earphones, does the increased isolation combined with the mild tinnitus make listening to music annoying?

Classical experts -- got any recommendations for works that remind you of heroism? I'd like to try some out at the local library, so nothing too obscure. Thanks.

I bought my Grado SR80s 20 months ago and I still enjoy them. I doubt I'll buy new headphones for a while. Anyone else found a nice headphone and stuck with it?

I hate to post a "what's the best.." question, but I'm looking for a good cheap used CD player that I can rip open and tweak for the hell of it. If I can find it on Ebay for about $100, it's perfect. Videoshielded suggested the Samsung DVD-709 but I don't think DVD players support CDRs...

Well, that settles it.
