    I have a Citation XX that I don't use 'yet'. It functions as it should but I have not gotten around to replacing the psu parts Bob here sent me a while ago. I don't need a new boat anchor. I've been told Matti Otala's finger prints are inside this one.

    but this thread is for solid state.

    For those interested this was Don Sachs (Jim McShanes's tech) personal unit. Has every upgrade and then some.

    It's pretty friggin' nice!

    Sweet. Jealous that you have the wood cases. I may have to build my own, though the 16 apparently is a hell of a room heater so I won't be encasing that one.

    New guy here. Love my new to me Citation 22, clean powerful bass, smooth, clear mids and highs. Paired with an Onkyo P306RS, and my much loved and recently re done Altec Lansing 315s the soundstage is amazing. DC offset checked out ok, and the heat it produces while cranked isn't objectionable. The speaker connectors aren't a big problem for me either, they're a little fiddly but not unreasonably so. I haven't had it very long, but so far I'm pretty happy with it.

    I bought the 11 and 12 when they first came out in early 70s.
    they drove JBL Olympus S8R spkr systems.
    After 35 yrs sold both and some yrs later bought another Cit 11 and use it regularly.
    Not been recapped but sounds great as when new IMO.
    Wonderful amps IMO.
    Now I want a 17. Anyone?

    Congratulations, and welcome. I picked up a restored 22 a couple months back, and have really enjoyed it. Easily drives my AR 3's. The only problem is that I also picked up just after that a McIntosh 1700 receiver, and I really like that as well. With only one system in the house, I have a bit of predicament as to what gets playing time. They are very different animals, to say the least. But I'm not complaining.

    Thank you both.This place is waaaaay more friendly than the 370Z forum. Lol. I got bit by the upgrade bug after I replaced the woofers in the old Sonabs and bought an SX750 to run them with in the backyard party hut. I started listening to the house system again and got a little carried away and popped the woofer surround on one of the Altecs(or sparkolansing to the purists). After I got them fixed I was listening to them and told my wife "I've always wanted some more serious power behind those things". I looked at several different amps, and liked what I read about the 22, so I bought one off of Ebay. This thing certainly fits the bill, the faithful Onkyo A-5 I got from my dad is packed away until I decide which kid gets it.

    Just found this thread...awesome!!! Here's my HK Citation systems. They're bunched together because I just bought my first set of tubes, so I'm rearranging and starting to sell off a bunch of gear I've collected over the past 9 months. Bought these back to back within a week of each other. That was a lucky week. Wish the 12's could be bridged just because.;)

    Citation 19.jpg Citation 19 back in the main system, thanks to minor fix by Crispycircuits. Very good match to recently acquired JBL L200t3, punch with clarity!

    Joseph if you're interested in unloading one of those Citations still--let me know! Is there a way to PM on here so we could work something out? I'm coming to this thread as the proud owner of HK 770 which has piqued my interest in the Citations

    I may be a latecomer to this thread, but I'm pretty darned pleased with my modded HK Citation Twelve. I bought it from a fellow AK'er and it's been my main office/workshop testing amp. It is fantastic with a Carver C-1 BillD modded front end.

    It is a 60 WPC MOSFET power amp based on Nelson Pass’ modification of Harman Kardon Citation 12. This was the first power amp Mr. Pass designed.

    The sonic signature of this amp is best characterized by this paragraph from Nelson Pass original article: “The amplifier is sonically a significant improvement over the original, particularly in the high end where the Citation 12's veiled characteristic is replaced by a detailed, somewhat sweet sound. The imaging and midrange definition are also much improved; but the bass response (one of the Citation 12's strongest points) remains much the same…”

    What’s left from the original Citation 12 is chassis, two power transformers, fuse holders and some power wires. Original PCBs were replaced with MF-12C ones purchased from diyaudio member Tazz. Schematic is an improved “complementary version” of Nelson Pass original design and can be found here:https://www.passdiy.com/pdf/citation.pdf

    The last owner, who did the mods, used 1% metal film resistors, mica and polypropylene capacitors and Nichicon Muse and ELNA Silmic II electrolytes. Transistors were matched by HFE as close as possible. Input jacks were upgraded to gold –plated ones and output terminals to heavy-duty 5-was binding posts. Input signal wire is now shielded and output wire is 16 AWG UP-OCC copper.

    Rectifiers in the power supply were replaced with IXYS HEXFREDs and filtering capacity bumped up to 16400 mkF per channel. The original power cord was replaced with IEC socket featuring built-in power switch.

    The original Citation Twelve generated quite a bit of hum which originated from power transformers and from loosely attached top cover. To minimize that hum, he installed an aluminum plate between transformers to provide some electromagnetic isolation and also serve as support for the cover. In addition, several new screws were added to firmly attach cover to the main chassis body and new rubber feet were installed. All these mods greatly diminished hum but not eliminated it completely. However, this hum is not heard in speakers: in my system the amp is dead quiet.

    The replacement MOSFET boards used are Citation 12 complimentary Mosfet version PCB's

    IMG_3061.JPG What an interesting thread. Did not know there was a H/K Citation Owners Thread. Since I'm a newbee Citation owner I thought I'd post some pics of my Citation 16Monoblock amps. Each is conservatively rated at 500wpc @ 8ohm and will handle 1ohm loads @ around 1000w, so my tech tells me. These were extensively modded/upgraded and fully rebuilt a few months ago.
    I'm currently in negotiation trade for my Marantz gear for a Citation I pre so fingers crossed. My intention is to take it to my tech to have it rebuilt as well.
    Well here they are currently mated to my Epi M1000. Have Citation amp dust covers will post pics later I guess when I take some..lol

    Wonder how it sounds. Mine was getting noisey crackleing, I thought it was driver transistors. I re-capped electrolytics in PS, Tone pcp, Driver pcp's, and Phono Preamp.
    Now it's quiet. And sounds GREAT. If you would not mind sharing how much did you have to put out for the Citation receiver? I plan on selling mine soon.

    Which transistors did you replace? With what? I'm very interested.

    After replacing the capacitors, my receiver was back to normal, no noise when powered up. Before it would make noise like a distant thunderstorm on an AM radio, for about 10 to 20 seconds. Also I had some DC to one of the speakers, it would travel in and then come back over a few seconds. I have seen the noisy transistor list and some of the transistors I replaced years ago on other receivers were on the list.
    :D
