Today, Kenwood KC-209 preamp $20.

Nice weekend!

My eyes poped out when I saw this HP 339a recently from a flea market. It had a few bloken / missing buttons but otherwise clean. The guy asked for $40 and I just couldn't resist.

The signal from the generator looked like crap at initial power up but it cleaned up up after some contact cleaning.

Loop back measurement shows around 95db THD for the singnal generator.

I also measured THDs for sine and triangle waves form HP 3311a against hand calculated results from output of a spectrum analyzer and they are closed enough (like within 0.5 db)

The only issue now is that the frequency scaling on the generator side is off by up to 15% in some ranges, but at least the signal is stable.

Needness to say I really happy with this new addition to my rack. Will clean-up/fix more when I have more time.

Happy, happy, joy, joy
I also have these speakers and found that they have very flat freq response apart from a massive suckout @ 3Khz which I presume is caused by lack of phase coherance between drivers at the crossover point. Also nothing much <80Hz. Also they are a pretty nasty load for an amp with 4ohm nominal impedance. Apart from that they are quite nice by the side of my monitor.

Hi Jim;

I made a nice hybrid amp from a similar thingy. I used MOSFET source followers to drive an output transformer, and a tube preamp/phase splitter. A nice bass guitar amp, as the result.

What I bought today:
16 bags of a concrete mix. No, not for speaker boxes. For my garden. I plan to build concrete boxes on top of a concrete floor on my backyard, and plant flowers and some vegetables there.
Nothing in the universe is perfect. The ideal things are the ones that are most optimal. Optimization criteria, what matters. When I hear "No Compromise Design", I want to take a sledgehammer and test how impact-proof it is.
