[Drakelist] L4B Question
*Hello, as you will be able to tell I'm not a tech, just a broke down Old Vietnam Vet who loves Drakes and am lucky enough to have a good collection.* *My question is I am in the process of redoing a L4B, using the Harbach Mods, soft start, soft key and power supply kit. I am having problems finding a place to mount the soft start, there is a alu. box mounted under the bottom, this is where the soft start needs too mount, can I remove this without any problems? I was told it was a low pass filter,And also where can I get the 10 mtr tuned input so that it could be used on 10 if I ever wanted to? It doesn't have the tuned input for 10, and the band sw has blue dots in that position. Sorry for being so dumb.* *Thanks* *Woody (KO4BG)* ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] L4B Question
Hi Woody, I added a Harbach Soft Start board to my L-4B about a year ago and I mounted it exactly where the soft start instructions suggested and it works very well. You will need to adjust slightly the binding post where the small electrolytic cap is mounted, but that is all. Good luck with your project and it is a very worthwhile mod to make. 73, Tom, W1CC On Wed, Mar 23, 2011 at 8:55 AM, Woody ko4...@gmail.com wrote: *Hello, as you will be able to tell I'm not a tech, just a broke down Old Vietnam Vet who loves Drakes and am lucky enough to have a good collection. * *My question is I am in the process of redoing a L4B, using the Harbach Mods, soft start, soft key and power supply kit.

Re: [Drakelist] L4B Question
Woody - Well, it's been 32 years since I did the 10m mod on my new L-4B but as I recall you should be able to simply replace the LP filter with a straight piece of coax (can't help with the 10m input coil/cap procurement). Once that's done you should have no problem putting the Soft-Start PCB in placeI just did it a couple of weeks ago. Contrary to the instructions my amp actually had the terminal strip oriented such that I didn't have to move it...I THINK it was built that way to accommodate the LP filter box and thus no moving required. Am sure one of the guys will chime in with info about the input components. If you look at the front panel you'll probably see that there's a small spot of gray paint in the place where the 10 should be on the plate tuning and band switch. Back in the day I took an eraser and gently removed that paint to reveal the numeralsYMMV. Good luck! 73 - Dino KL0S On Mar232011, at 0855 AM, Woody wrote: Hello, as you will be able to tell I'm not a tech, just a broke down Old Vietnam Vet who loves Drakes and am lucky enough to have a good collection.

[Drakelist] TR7 refurb
Greetings to all, I just purchased a TR7 that needs some TLC. Need recommendations on paint for the cabinet, source for plastic end caps (watching some on Ebay currently), microphones (yes, I realize a lot of personal preference is involved here). Wondering if anyone has adapted a computer/cell phone headset to the TR7? Thanks for the help. Looking forward to getting this on the air. 73, Randy K4EZM ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Re: [Drakelist] t4x cw problem
Bill - Yes, a dried out (high ESR) electrolytic at C132 allows the SIDETONE from V9a AROUND the D8 keyer diode, and send it on to V11 via the B+ bus. Nice when they're easy! :-) 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs www.k4oah.com Bill Hendrickson wrote: Garey...I think it was you who said c132 was giving me a sidetone problem on my t4you were right...replaced it and no more errant sidetone 73 Bill ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] TR7 refurb
Randy, I hope someone will chime in on the paint, but Mike March, K4QU,makes the plastic end caps FAR cheaper than I have seen them on Ebay. He has three sizes, as I remember, to cover the TR7, accessories and the L7 amps. Email him at mikek...@gmail.com . No connection other than a VERY satisfied customer. Google March Magnetic Paddles and see some of his handywork!! 73, Don, WB5HAKI ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

MY R4C HYBRID #27948 HAS LOST ABOUT 20DB OF SIGNAL STRENGTH. IT SEEMS TO HEAR OK BUT THE S METER SHOWS ~20DB LOWER ALL THE TIME. IT HAS 4 SOLID STATE TUBE REPLACEMENTS FOR 6EJ6 TUBES. I HAVE SWAPPED THE TUBE REPLACEMENTS AROUND A FEW TIMES WITH NO CHANGE IN SIGNAL STRENGTH. IS THEIR A WAY TO CHECK THESE SOLID STATE REPLACEMENTS?
