Today, the Smoldering HULK of a SB-200 came in from Ebay. I paid DEARLY for it, almost $200, which is considerably more than I paid for a perfect working SB-200 that I got at a swapmeet. That one went for only $125 and is my backup HF kilowatt. But this one is just for playing and experimenting with. The good news is that more of the amp is there than expected. It had a line cord, the original Relay, the Power switch and many other parts. Of course, the final circuit has been ZAPPED, no tubes and the power supply PCB has been BRUTALIZED! That's OK, I am replacing all that! As mentioned in the thread on Vaccuum relays, I will use the Jennings RFID-26S relay along with the Mitrek relay as suggested by Jim W7RY. The good news is the Transformer is GOOD!!! That was my greatest worry on this! The Meter has been wasted, but I got it to work enough to measure it's parameters. It seems to be a 200uA movement with .28VDC across it at full scale, so that comes out to be a 1400 ohm impedance. I have a Heathkit HM-102 wattmeter that uses a 200 uA meter and is the same size, so will see if I can just trade out the meter plates and use that one. I have a surplus of HM-102s so I can sacrafice one. Time to order all the replacement parts from Mouser! And start building! I have a pair of Cetron 572Bs n the house SOMEWHERE, but couldn't find them this morning. I hid them someplace SECURE where they wouldn't get broken. Of course I have FORGOTTEN where that was, so alotta looking to do. But the project is underway. yes, I KNOW SB-200s won't work on 6, but alotta people have done it successfully, so it CAN be done! And I will do it!
