The KT-550 was legendary engineer Stu Hegeman’s last work for Lafayette before he moved to Harmon Kardon. The circuit of the KT-550 is the direct predecessor of the HK Citation II, and is extremely similar. I have had this example for about 1 1/2 years now. I found it in original and very dusty condition at a neighbor’s garage sale, gave it a very thorough cleaning, and performed a full electrical restoration with the parts and values recommended by Jim McShane. The only passive components that have not been replaced are six of the wire wound resistors that measured in spec. The power supply now uses 1000 PIV fast/low noise UF5408 diodes for rectification and higher value capacitors from JJ, F&T, and Nichicon. Film capacitors are Solen PPE, Russain paper-in-oil K40Y-P, Cornell Dubillier “orange drops”, and Panasonic. Small-value caps are Cornell Dubillier silver mica. Resistors are all very high quality units from of Precisions Resistive Products, Vishay-Dale, Mills, KOA Speer, Allen Bradley, etc. 221 screen stopper resistors were also added on the power tubes. A full parts list is available on request. The 6CL6s and 6BR8As are the strong-testing vintage units that were in the amp when I got it. The 7027As are reissue Tung Sols with approximately 100 hrs on them. Input jacks have been replaced with modern gold-plated jacks, and a three-prong power cord was installed in place of the original non-polarized cord, with earth ground tied to the chassis for safety. The bias meter works perfectly, meaning that setting it to the indicated mark does in fact result in the correct current through the power tubes. The AC balance setting does not work. However this is moot since the original method of measurement didn’t reliably have better results than just setting the pots in the center. The AC balance has been set for the current tubes, however, by matching the signals at the power tube grids of each section as closely as possible with a dual channel oscilloscope. Actual power output at the onset of clipping is around 40wpc. I can provide 1kH and 10kHZ square wave samples as well if that tickles your fancy. The paint on the transformers and chassis has its share of scrapes and scratches, as seen in the photos, but it’s still a very handsome piece with a nice patina. Internally, some of the potting material from the power transformer has liquified and oozed down through the hole in the chassis. This doesn’t affect anything, but in case you’re curious what the black blob above the choke in the 5th photo is, there’s your answer. The amp will come with a copy of the original assembly and operating manual as well as all of the original components that were replaced. The amplifier works as expected, and sounds incredible. It’s been a labor of love and I’ve enjoyed it thoroughly, but I’ve found I prefer the sound of other topologies, so I’ve decided it’s time to pass this along to someone who will use it. Please let me know if you have any questions or would like additional pictures of anything.

You are looking at a Vintage 1960′s Lafayette by Univox U-320 2×12 All Tube Combo Amp. Univox was the builder on Lafayette amps. They are virtually a clone of Univox. These amps are real sleepers. They have great Tone. Lafayette was a budget economy amp back in the 1960′s, but just like Valco they are appreciated for their Tone. We have upgraded this amp with 2 Jensen C12R speakers. These speakers provide warm low and mid response with smooth/bright highs. When presented with overdrive distortion, it presents smooth crunch with low-end focus. If you are after that mid sixties trashy rock tone, this amp will do the trick. Our Amp Tech just serviced this amp. You won’t have to spend any additional monies on it. Gig Ready on Arrival!
