I have a working Eddystone 640 and also a Marine Rx by Eddystone that uses dual gate mosfets. It used to belong to an elmer vu2ja Joe who I knew in the 60's. His xyl gave me his Rx and I have preserved it! Raj At 01/09/2017, you wrote:
Thanks for that, Arv! and valid points from Jerry, too - fond memory of brief acquaintance with an Eddystone 640 :) Now to investigate the junkbox ... For *really* fine tuning, try taking the 10k dual to a 100k dual, and the 1k (now really fine) can then be what you have up to 10k (original effect). Ratio gives you the 'gearing'. Could be a bit of exposed wiring - bypass the 'fine' wiper? |
