One thing it has is a Medival Soft Start. A BIG Brown resistor (of unkown Value) is in the AC line until the contacter shorts it out. Think the kind found in the Harbach or W7RY would be a better idea. So I am starting to design the control circuitry. It could be done with an ARDUINO, but it would require a MEGA or an I/O Port extender! An LCD readout would be pretty, but I am thinking of a Remote Readout and control panel similar to what I did with the SB-226, which was a Masterpiece in Over-Engineering! So far I Have about 12 LEDs that have to be lit for various functions of an Amplifier Cycle. AC ON Led, HV Led, SCREEN Led, Bias Led, Filament Led, FAN Led, WARMUP Led, COOLDOWN Led, RX, Led, TX Led, READY Led and maybe some more! He who has the most LEDs on their Project WINS!!! The Warmup Led will run while the Filaments are lit before the HV and SCREENS are enabled. The Cooldown Led will run for a few minutes with the fans on after the amp is shutdown from operating. Ready Led lights at the end of the Warmup Cylcle showing the Amp is ready for Transmit. IF an LED is NOT LIT in the particular Cycle Step: "HOUSTON WE HAVE A PROBLEM!!!!' (or there is a problem with the LED as happens frequently in the SB-226! As said, it could be done with and Arduino, but the programming on those is really tough (I sure have torn my hair out trying) and I am an OLD SCHOOL Guy who likes 4011 Nand Gates and RS FlipFlops! In the famous (and still in DAILY SERVICE) is the Famous Rotator Controller I built for the Twin Roof tower rotors. It has somewhere around 40 CD4000 series ICs in it. That also could be replaced with an Arduino, but the programming would require a Computer Genius!! So the Amp, Once tuned for the SSB Section of the band, shouldn't need to be Retuned unless I decide to run a KW to Access my local Repeater. Not sure where in the already Full Radio shack I am going to put this amp, but it will Go Somewhere. One location that would have worked good was under the bench. The problem came when it turned out the blower interfered with cabinet enclosure. I have a perfect 16 inch high cabinet sitting on the front porch (where it is been in the rain and sun for the past 20 years!) Probably full of Black Widow Spiders!
