Lafayette KT - 600 Stereo Preamplifier Preamp With Telefunken 12ax7 Tubes
Item History & Price
| Reference Number: Avaluer:7024847 | Brand: Lafayette |
| Model: KT-600 | UPC: Does not apply |
This very rare preamplifier made by Lafayette is one of the early stereo preamps and is very sought after now because it is said to sound like the Marantz 7c preamplifier which costs many times more. This is a Stuart Hegeman designed preamplifier that shipped with 7 telefunken 12ax7 tubes as part of the original kit.
This is an amazing specimen and with a bit of tender care can become the centerpiece of an audiophile collection for decades to come.
It is in amazing cosmetic shape... with a few small flaws.
I inherited this piece and always planned to restore it but life circumstances have changed and I'm ready to see it go to a good home. Below is a complete description of its history to my knowledge and from what I could find in the original owner's notes:
Condition:Cosmetic condition is very good. The faceplate is nearly flawless. The preamplifier has all of its knobs, although you can see the front volume knob has some damage and is missing the metal accent. The scratch filter knob has a crack in it and should be glued back together.
There are some minor chips in the metal housing (pictured) and some slight discoloration on the top near the venting holes.There was some lettering written in permanent marker above the jacks on the rear that was removed - it is evident that the lettering was removed - the metal reflects differently at these points on the rear plating. The preamp includes all of its original tube covers.
Functional condition:The preamplifier appears to have had the large transformer replaced - judging from the original owner's notes, this happened sometime around 1999. See the photos for detail. I believe it was in active use around that time.
The preamplifier was briefly powered on within the last year to test for audio channels - the light works and I was able to get stereo sound from both channels, but one channel crackled a lot when wiggling the "stereo function" knob.I can't comment on the functionality beyond that brief test. The test was nearly a year ago - this is sold with no guarantees, as-is. It likely will need work from a qualified technician to be fully functional.
The preamp appears to have all 7 original telefunken tubes, I pulled them all and confirmed that they each have the diamond symbol on the bottom, but I left the tube covers intact to protect the lettering.
This piece will ship with the following documentation:
Pictoral 2, 4, 6, 10, and 11Mounting templateA few photocopies of the schematicPhotocopy of the photofact folderOriginal owner notes describing the new transformer
Will ship packed securely with direct signature required and insured.
