I reported to Scott and Grayson that I had finally gotten around to changing the three aging 6U8 tubes in my Mate for the Mighty Midget receiver. I replaced them with three more youthful 6EA8s. This switch really seemed to perk up the old receiver. I’m listening to 75 meters on it right now. <\/i><\/b><\/span><\/p>\n

Speaking of 75 meters, Scott sent me this picture of his latest effort: re-building a Heathkit HW-12. FB. This is a way of experiencing (or re-experiencing) the construction of a Heathkit. I did something similar, but much less complicated) with a Heathkit VF-1. Scott did a wonderful job taking this old rig apart. That PC board looks great (see photo below). <\/i><\/b><\/span><\/p>\n

Scott’s e-mail: <\/b><\/span><\/p>\n

Hi Bill and Grayson, I\u2019m glad to hear of your good results with the 6EA8\u2019s in your MMMrx! I had similar results when I finally got rid of the 6U8\u2019s with their iffy performance and went with the 6EA8\u2019s. I did put a set of 6GH8A\u2019s and tried it out, it worked, but I don\u2019t have any data on performance improvements. After completing the outboard power supply and audio amplifier, I\u2019ve taken a break from my MMMRx and it\u2019s sitting there on the bench. I\u2019ll get back to it in a while. <\/b><\/span><\/p>\n

In the meantime I\u2019ve started a new project where I\u2019m re-kitting a Heathkit HW-12 eighty meter transceiver. I have completed the disassembly process including the pcb. I bought a Hakko vacuum desoldering iron for taking all (ALL) parts off of the pcb, and it\u2019s bare now. I\u2019m planning to start rebuilding this coming week. 73 Scott WA9WFA <\/span><\/u><\/u><\/b><\/p>\n
