Hi All,
I've just bought a Lafayette LR-4000 with a bad channel and I need schematic or service manual to repair it.
I've checked the usual places like HiFi engine but it seems to be Unobtainium. Would anyone here have a copy.
I need only the amplifier section.

Thanks,

Techfixer

Hi Techfixer, I also have a Lafayette LR4000. I picked it up from ebay around 2006. I lucked out. The ad said it was used in the guys garage for years, bought it off his brother, and now had scratchy controls with dead spots in the volume, and a power cord shortened to about 6 inches to fit on a shelf with a plug right behind it. I won it cheap. There was a thick layer of "felt" like dust that smelled of stale cigarettes. After a couple of cleanings and replaced the cord, I had a nice working unit for years. the AM and FM section was a little jacked with the alignment being off, but not too bad. It did sound great playing records, quad, stereo, and mono on the various setting options. About 4-5 years ago, I started getting intermittent "pops" or "crackles" in one of the channels and the sound wasn't as good as it used to be. I found a place not too far that worked on vintage tube radios, and solid state gear. I took my stereo in for a "check up, alignment, and find out what else might be needed". Unfortunately, they did a poor alignment, and replaced the 2 main filter caps, that's it. It still had some issues I described, and the AM alignment was for crap. About 2 years ago, There was a small pop, and I lost one of the rear channels. No fuses were blown. I replaced the unit with a Yamaha natural sound of the same era. It sounds good with most records and FM listening, but nothing as good as my LR4000, which I still have on a shelf. For about 10-12 years I have learned to work on old tube radios, but am a bit intimmidated with the solid state stuff of the 70's. However, after researching over the past year, I think I will attempt a recap, and repair of my Lafayette. Sorry for the long post. I've been a "lurcker" on the forum since aorund 2008. This might be my first post? I am interested in how your repair turns out, and if you have any tips.
