Tangent's PIMETA Breadboard
-Socketed IC's, resistor block, bandwidth and cascode resistors.
-Molex KK pins - tin for PS, switch and LED; 20um gold plated for the signal pins.
-Soldered - caps, pot, R1/R2 divider, LED resistor
Pls notice that cascode resistor sockets are mounted low with respect to the OPALR socket and transitors are firmly pressed to the board so there's enough clearance for a resistor to fit below (dual) BrownDog.
And same PIMETA - mounted in a wooden box
Here's the final configuration (for the relatively blant Sennies 580)
-AD8620/8610
-Diamond buffers (MJR243)
-4x1000uF Panasonic FM + 2x3.3uF Illinois Capacitor film caps
-Gain is 6.78
-Class A casscode
-10K pot/100K ground res
-24V regulated PSU (30V/400mA wallwart + "drop-in" LM7824)
