not quite what you were looking for, but it has a bill of materials in addition to users manual stuff. File is too big to upload. send me a message and I can send you a copy by email.

you can also go there directly to this link:

I took the liberty of rearranging the title. Perhaps that will help.

I am looking for all informations, mainly photos and a schematic diagram, so as a high resolution pic of the attached pdf from post #1.

Thank you very much for this URL - I have download the pdf Owner's Manual (Operating Manual). It is like a real service manual, but unfortunately without schematic.

About the there mentioned output power devices "H43019955" (factory number from Harman Kardon) there are no informations. Funny is, that by the part lists also the price information are listed ("H43019955" for $31,90).
Perhaps this amp was the first commercial solid state power amp from Harman Kardon, maybe not OTL and still germanium instead the later introduced silicon power devices.

The associated pre amp "Citation A" you will find about Ebay Item number: 250653508448

Thank you for your effort.

check additional keywords to get more information about google:
1) "ハーマンカードン Citation" (of special interest for Google Image search to get various pics of the "Citation" series in general)
2) Harman Kardon "CitationB" (instead "Citation B")

Now I have found this japan URL with interesting informations:
ƒJ�[ƒI�[ƒfƒBƒI�@harman / kardon(ƒn�[ƒ}ƒ“ ƒJ�[ƒhƒ“)�@�»•i�î•ñ
(http_www.groove-int.jp/maker/harman/index_html)

the translation claim about the year 1962, that is world's first (from Harman) developed pre- and power solid state amplifier "Citation A" and "Citation B".
If this is true, I can good understand the rare informations on the web. Perhaps only few hundred devices was go in production.

But Cervin Vega claims also this, (however already 1957) go to post #10 about
Overview of Brands and Models from first Solid State Audio Amplifier Components want.

However - the power amp "Citation B" seems to be a very interesting vintage device maybe even equipped with germanium power devices.

the informations about
ƒJ�[ƒI�[ƒfƒBƒI�@harman / kardon(ƒn�[ƒ}ƒ“ ƒJ�[ƒhƒ“)�@�»•i�î•ñ
seems to be right - go to
http://www.harmankardon.com/resource...03BROCHURE.pdf
but except the owner's manual (operating manual) about
Harman Kardon
I discover no additional informations. Today I have send an e-mail to Harman Kardon. If I get the wanted informations from there, I will report.

about
High Fidelity Magazine Reviews Part 1
(High Fidelity November 1964 Volume 14)
I read, this was no commercial amplifier. Instead this it was an amplifier kit.

from "HCGcustomersupport1@harman.com"
I get today the information, that no schematic is to find.

It might be, that there are a model from JBL/Lansing/Altec-Lansing with identical PCB's in use than Harman's "Citation B".
Is my estimate right?
