Drake L7 linear amplifier RF Deck #2 only, unpowered walkthru, this 1 is clean, I Likkie.

Drake L7 RF deck. This one looked great but had some internal issues. The band switch was bad and is a known problem with the L7's. The L4's used a much more robust band switch. Since I had deck number 1 going with a good band switch and all the Ham bands active and working, I decided this was going to be my sacrificial lamb and it has been modded up a bit. Since the band switch was bad, this one has been monobanded. It has been mono'd on both the Input and Output side. 1 variable Input coil set to 10-15 meters with variable tune and load on the variable input coil, 1 output fixed tank coil with variable tune and load caps for the output. Also, the obsolete 120v bias scheme for cutoff has been replaced with cathode resistance for cutoff, and last the operating bias is using a variable Bias PCB bought off Ebay. The Bias can be adjusted from 3-30v and normal class AB1 bias is about 9.5v with stock plate voltage. Can't wait to play with this one.
