Dave, Ask Jeff Weinberg W8CQ, He jusr went through my L4B power supply with a fine tooth comb and fixed it and is sending it back. He can tell you and sell you what you need! 73 Bill K9BuB

First question: PS has a sn of 142X. This sn does not seem to match up to the ones on wb4hfn's site. Any history? The last Drake rig I ever saw with an X was a TR-6 prototype that I used back in the 70's. Second question: The caps in the power supply are blue sprague atoms with both leads on top of the cap and not axial. There also seems to be a skinny board at the base of these caps. I have'nt taken it apart to better understand the connections or modifications as yet. I'm assuming this is not original, since I understand Drake used axial capacitors. Am I correct here? And did Drake ever do any of the mod's outlined above? Looks like a pro job from looking at the tops of the capacitors and the little long skinny boards at the bottom? Before I picked this up, I had it in my head I'd need to get a upgrade board from the Heathkit Shop, but now I'm not sure that will be necessary, at least in the short run. Oh, I have'nt fired it up yet, so I cannot comment on the smell or anything else. I'm planning on bringing it up slowly on a variac. I was told it had been in storage for around 8 years. Thanks, David Wd9cmd_______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
