Title: Ranger Mult/Driver Post by: N8ETQ on January 28, 2017, 07:07:52 PM Voltages Ok. Tube OK. Hit the Band sw. with DEOXIT pretty gud today. Spent 3 hrs. at the "Joint" waiting for my XYL and still can't figure it out..Sad.. Gonna "Skip" church tomorrow and hit it harder in the AM... What am I missing? Low grid drive pulls the clamp in.. It appears to be working. PA Escr 15V.. SB 225.. As usual these days it's a highly modified example of a ranger with the keying sequencer board added in. Appears to have been "Factory" assembled by virtue of the rivets for the tube sockets... The sequencer was "added" judging from all the "Black Tape" splices...

Turns out R12, a 470 ohm 1 watt. on the front of the band switch (Under that shield) went to 7.5 K...
