This is a CTech Electronics Exclusive.Note: We also sell the 140014001000 50V can 50505050 350v separately in our store.These caps are all low esr. The soun...d improvement is substantial. Bass is now tight instead of a mushy mess. This results in better mid-range tone and feeling of cleaner upper mid-range and extended highs. INSTRUCTIONS WITH PICTURES AND SERVICE MANUAL INCLUDED AS WELL AS FREE TECHNICAL SUPPORT WITH KIT PURCHASE. If you have purchased a Marantz 7 7C Preamplifier and have not changed the power supply, audio bypass Electrolytic capacitors and Selenium rectifiers, you have a time bomb on your hands. The preamplifier is not performing to its full capability as well. In fact stock, it sounds very inferior to even an ARC SP3A-1.Don't fool around with NOS capacitors unless you are looking for trouble. Don't modify your chassis to accept capacitors that need clamps and devalue your amplifier. These are direct fit cans. Brand new. Please read the Disclaimer below before purchasing.

Supplied as well are the five power supply series dropping resistors.We supply a replacements for the 220uf and 100uf discrete cathode Bypass capacitors as well. These are high temperature axial electrolytic capacitors. We also supply a bridge rectifier and silicon diode to replace the Selenium parts. Also supplied is a Zener diode for the high voltage supply and 3 extra diodes for the filament supply to compensate for lower voltage drop of the silicon parts.Terminal strips are provided for mounting.This kit also includes all (12) audio coupling capacitors on the turret board and on the top side on the tube sockets. These are high quality metalized Poly Caps such as Mallory 150 M andOr Illinois Capacitor.We also supply a service manual and installation tips document. Disclaimer:Please note that this kit is not to be used by inexperienced users. There are high, potentially lethal voltages inside the Citation II and other tube amplifiers.

For Sale is One Lafayette KT-600 Preamplifier "Master Stereo Audio Control Center" If you are reading this, you probably know the KT-600 is widely considered one of the finest tube preamplifiers ever made. It was designed in the late 50's by Stewart Hegeman for Lafayette, and has been a widely sought after classic ever-since -- famous for its bold, authoritative sound. In its Winter 1998 Review of vintage tube preamplifiers, The Absolute Sound gave the Lafayette Kt-600 their highest vintage rati...ng, and said it possessed "...Out of this world accuracy, solid imaging, and a certain odd allure akin to the Marantz 1." In addition to sounding incredible, this preamplifier is unique for several reasons: First, it can play back any record properly by virtue of its 28 combinations of roll-off and equalization settings. Second, it employs a stereo balancing circuit based the null principle, allowing you to perfectly balance each stage of the preamp. Third, and crucially, its frequency response is flat from 5Hz to 40kHz for unconstrained, clean playback. It represents one of the first implementations of Hegeman's wide bandwidth approach to audio design, the principle that served as the foundation for all his later work: the KT-550 amplifier, Citation I and IV pre-amps, and Citation II and V amplifiers. (Note to other sellers: stop stealing my descriptions. Write your own) Condition Aesthetically, the preamp is stunning. It is probably the cleanest example you will ever see. Use the photos to judge for yourself. Please note: some of the knobs were cracked and have been repaired. They are all stable, perfectly functional, and show well. But they are not flawless. Electrically, this preamplifier has been subject to judicious electrical restoration. It is in excellent working condition. And while the KT-600 was never the quietest preamp, this one outperforms the original specification.The restoration work was done by me, as follows: Power Supply Work All the electrolytic "can" capacitors were re-stuffed with premium modern electrolytics: (1) Mundorf MLytic AG MLGO, (2) Mundorf MLytic HV MLAL, (1) JJ C-EC47-385, and (1) Nichicon CY series capacitor. On photo shows one of the Mundorf caps with its "can" removed so you can see it. The selenium bridge in the filament supply was replaced with (4) MUR860 diodes The selenium rectifier in the B supply was replaced with (1) UF5608 rectifier All lt1 watt resistors in the PSU were replaced with Takman Rey metal film resistors The 2 watt 10K resistor in the power supply was replaced with a NOS Mills MRA-5 non-inductive wire-wound resistor The 0.1uF heater supply bypass capacitor was replaced with a high quality polypropylene capacitor Some of the red B wiring, which was damaged, was replaced with silver plated copper wiring with Teflon insulation The Nichicon CY capacitor was used in the reservoir position because it can handle tremendous stress (it's rated at 12000 hours) and the cap in the reservoir position sees a lot of it, especially at startup. The JJ capacitor was used as the filter capacitor for V7, which is active only when calibrating the channels, or when using the "blended" output jack. The Mundorf HV MLAL caps were used as the filter capacitors for tubes V1, V2, V3, and V4 (the tubes that are in the audio circuit during normal use). The Mundorf AC MLGO was used as the filter capacitor for the filament supply. Takman Rey resistors are subject to exceptionally high quality control standards, are extremely quiet, and are considered great sounding by those who believe resistors have a tone. I used matched pairs for each position in each channel. I used an oversize Mills wire-wound (not the Vishay version, an original Mills) in the highest current spot to make sure the supply is as quiet as possible. Audio Circuit Work All the original carbon composition anode and cathode resistors (4 per tube) -- which carry the most current and, therefore, produce the most noise -- were replaced with Takma

Marantz 7C Pre-Amp Excellent Condition. Condition is "Used". I took my uncle to our local Marantz dealer in the early sixties and bought a Marantz 7C pre-amp and a 8B power amp along with a JBL Ranger Metrogon stereo speaker system. He used the Marantz units for about 10 years and then put them in storage, a warm dry area.I recently hooked them up and they worked perfectly. The covers have never been off and they have the original tubes. No hum at all indicating the power supply caps are in good... working order. All controls, switches, and inputs work flawlessly. This listing is for the pre-amp only. See my other listing for the 8B power amp.On Oct-30-20 at 20:53:44 PDT, seller added the following information:I do accept returns. I just don't know how to revise it on my listing.It was something I overlooked when it was posted.
