I've been looking for the service manuals for the BK Precision 1590a.  I can find the schematic/parts manual and the owner's manual, but the service manual is very hard to find. (I do know that it exists though!)

I have gone through every website listed here and more. Any help is appreciated!


There is also a B&K 1570A which may be very close, or nearly identical, have you looked for that one, I think I once found that SM, it may have stated 1570A/1590A I don’t exactly recall.

I am given to understand the Kenwood/Trio CS–2100a Oscilloscope is electrically the same as the BK 1590A, and you can download a full 194 page S.M. for the Trio CS–2100A from Elektrotanya!

It's an enigma that's what it is!! This thing's not fixed because it doesn't want to be fixed!!

I have found a Yokogawa CRO which has extensive rat damage. The model number is 3663. Couldn't find anything in the internet about the existence of such a model :-//
All the PCBs inside look OK, non of the capacitors seem to have leaked at least from a visual inspection. However rats have chewed on almost all the inter-board wires.

If anyone has any information on this specific model or something similar, That would be highly appreciated. A repair manual or a schematic would be a godsend. Thanks in advance.

IT's a Yokogawa 3663 CRT oscilloscope, 100MHz 2Channels

I cant find any Hitachi markings. Back says "Yokogawa Electric Corporation"
It's indeed possible similar products exist from Hitachi, maybe OEM

Edit: This scope does indeed look very similar to Hitachi V-1050F. atleast from the front panel

Confirmed, This is Hitachi V-1050 scope. Schematics match 100% and even the wire colors are the same. Maybe Hitachi made these and Yokogawa rebranded them? because the V-1050 has lots of resources online and seems quite well known.

Anyways, looks like its time to get wiring some crusty connectors...

Hello,
I can't find the service manual or the schematics of the spectrum analyzer HAMEG HMS1000 (or Rohde & Schwarz HMS-X, it's the same device).
I have checked on most of the links listed here.

Thanks !

Artek manuals sad news
« Reply #107 on: April 29, 2023, 04:12:45 pm »
Artek has long been a good source for high quality scans of manuals. I ordered a download two weeks ago and it did not arrive so I called and was shocked to hear that Dave, the guy behind it has died over Easter. His wife, Linda, is trying to keep everything up but she was never shown through the operation of the web site. For now, do not expect to get downloads. She is fulfilling CD orders. She is hoping to get the downloads working but is not sure how long that will take. For now do not expect to get a download from them.  Just order CD's.
