Re: [Drakelist] TR7A Knobs
Good Morning Garey. My wife Muriel thinks you are a Miracle Man! I had told her of my unsuccessful struggles with the knobs. Immediately after reading your email last night I went into my Radio Room, performed the Handkerchief Trick and both knobs came off smoothly and without undue effort! Thank you.

No hidden tricks. I use a couple of thicknesses of cardboard over the bottom trim strip as a fulcrum for a screwdriver blade. The trick is to pry slowly and under control. The cardboard is to spread out the force against the aluminum trim strip so as not to damage it. Another old time trick is to work the edge of a handkerchief behind the knob and gather in such a way as to give you a bigger handle to pull on. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com John Stringer wrote: I have tried to pull off the Aux7 and Mode knobs without success!

[Drakelist] L4 PS
Hello, Just acquired an L4B plus L4PS. 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.

Re: [Drakelist] L4 PS
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 --- On Sun, 8/10/08, David Chris Drake [EMAIL PROTECTED] wrote: From: David Chris Drake [EMAIL PROTECTED] Subject: [Drakelist] L4 PS To: drakelist@zerobeat.net Date: Sunday, August 10, 2008, 5:09 PM Hello, Just acquired an L4B plus L4PS.

Re: [Drakelist] FS: Unique Drake Service Supplement CDs
Hi all, I just wanted to say that I ordered a CD for B line recently and used it to help locate parts in the premix circuit (it' quite a mess in there). It saved me a lot of time (trying to locate parts and test points) and as a result, I finally got one of my T4XB's running, and got it on the air. The CD's are worth it (much like the AC4 upgrade from Mike Bryce), and should be required if you have one of these radio's. I will be getting the TR-4 one soon as that will be my next project. Thanks Garey for your time on this! 73, Ryan, N7QJ -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Garey Barrell Sent: Saturday, August 09, 2008 6:56 AM To: Drakelist Subject: [Drakelist] FS: Unique Drake Service Supplement CDs Unique supplemental service information CDs available for the Drake TR-4, TR-4C/Cw/CwRIT, B and C Lines and the 2-B receiver. These CDs are NOT just scans of the original manuals that were included with the equipment when new. While high resolution scans of the original manuals ARE on the CDs, what they really offer is high resolution color photos of the under chassis and individual PC boards of each unit with all parts identified and keyed to a parts list. This information is not available elsewhere and really makes a difference in servicing these units.
