*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
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
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
All,
I was working the CQ WW DX Friday night (C line and L4B) on 40,
picking up a couple new ones, cndx here were just so,so. All was
well, shut down. Resumed Saturday morning,
20 sounded in great shape. Tuned up the twins on the new band,
kicked in the L4B, and nothing. Amp turns on,
4 matches
