This listing covers a complete Restoration for your Harman Kardon Citation II  or Citation V (699.00) Tube Amplifier; a  complete power supply rebuild, and replacement of all Audio capacitors.  The price does not include return shipping (or packing if a new box is required.)
If you have just purchased an amplifier, have it sent to us for a complete restoration. Here is what the restoration covers, there are (2) inspection  groups included in the price:
Inspection Part 1
Visual inspection of the top and bottom of amplifier, bottom cover off. Look for burnt resistors, leaking capacitors, blown fuses, defective tubes, defective rectifier diodes and other defective components etc.
Power the amplifier up in slow stages, with a Variac, to avoid shocking older electrolytic in the power supply, and to allow them to reform.
Check all power supply voltages at the specified operating line voltage, according to manufacturer specifications
Check all resistances at tube pins (when specified by manufacturer)
Check All Electrolytic Capacitors for ESR (Quality) using an 88A Capacitor Analyzer, leakge and value
Check audio coupling capacitors for leakage, quality and value
Check all vacuum tubes on an Amplitrex AT-1000 Lab Tester
Check bias current for all output tubes to ensure it is within normal operating range
Check condition of input jacks and output terminal strips
Check condition of switches and tube sockets
Check for signal throughput and condition of output transformers - inject  1Khz signal at each channel input and check for output at each channel's speaker terminals (loaded at 8 ohms). Check output transformers for continuity and winding shorts.
If anything above is found  NOT correctable by simple means (no significant additional labor and no parts), issue Initial Report to customer by email or call.  If customer decides not to move forward, only a .00 bench fee + return shipping is charged.
At this point the Power Supply is completely rebuilt using our German made capacitor refurbish kit (See Picture- sold separately for you do it yourself types in our Ebay Store).  These are all direct fit capacitor cans.  No brackets, clamps or chassis modifications. This is unlike other restorations which diminish the value of your amplifier. We also replace all other discrete Electrolytic capacitors with high temperature, high quality types. The power supply main and bias diodes are replaced with high quality types.
In addition, all audio path capacitors are replaced with high quality Illinois Capacitor MPW polypropylene types, 600 V rated.  Power supply resistors are replaced as well.
Inspection Part II
Re-check Power Supply and operating voltages
Clean tube sockets and switches with Deoxit 5, re-tension tube socket pins as required
Measure Output Power into 8 Ohm Loads
Measure sensitivity for full power output
Measure Channel Balance
Measure distortion (THD) @1Khz, half and full power output
Measure frequency response (20Hz,40hz, 100h,250Hz,500Hz,1Khz,5Khz,10Khz,15Khz,20Khz,25Khz 30Khz)
System listening test - Assess quality of sound
Light cleaning of chassis
Issue Final Report to customer by Email or Call
If we find anything seriously wrong in the Inspection Part 1, we will call you or email you an initial report, so you can decide if you want to repair things or not and upgrade the power supply. If you decide NOT to go ahead, or your amplifier cannot be repaired, you only pay a .00 bench fee and return shipping charges.
After completion of Inspection Part II, we will provide you final a written report, by email (or USPS if desired), of you amplifier's health. A copy will be returned with your amplifier. This report will list recommendations for improvements as well as potential problems found, with costs for possible repair or upgrade. No further work will be performed without your consent. All you pay at this point is the listed price plus return shipping.
This restoration does not include return shipping or any additional costs for labor and parts/tubes to repair defects found above and beyond those stated in the listing. These will be billed separately should you agree to go forward.
Our pricing is introductory pricing, so take advantage of the low pricing now, and have your amplifier checked thoroughly. Please double box it and ship it to us insured. We will return it to you in your packaging. If your packaging is damaged, there will be a nominal charge for packing materials, so make sure you packing is rugged..
