I’ve been working on a KW-4077 reel to reel. This thing tried to win and remain dead but it seems to be finally working. Not quiet the same level of gort’s 650 rescue but it is a Kenwood.
Picked it up from a buddy. He got it from a musician “It doesn’t work.”
Removed the face plate and found some of the reel belt. Ordered new belts from Bob at Vintage-electronics.net, cleaned up all the dried out grease, added fresh grease and oiled the capstan and reel spindles and got the mechanical linkages working. Record latching cam wouldn’t catch but studying how it worked found more dried grease.
Cleaned the record and gain pots. Cleaned heads and tape transport. All lights work.
Played ok but right channel sound muddy when compared to the left channel. Replaced the coupling caps and other electrolytics with fresh caps. Got better. Finally lost right channel after about 1 hour of recording. Traced it down to a failed 2SC-871. Subb’d in a KSC1845 and channel works and sound much better.
This is my 3rd reel to reel. Had my Dad’s Sony in college and traded a TEAC for Fisher X101-B. I restored the Fisher and is our ‘living room’ system.
My Raspberry Pi music server is so much easier to listen to music but nothing like spinning reels and the analog sound. Plus it is a good match for my 9400.
