Does anyone have manuals for these cards? I'm looking for the 16530A/
16531A Front Panel Operation Guide and 16531A service manual,
preferably in PDF format. If anyone has these they can send to me, or
know of a site I can get them from or a dealer I can buy them from,
I'd appreciate it. Thanks.

Hi,
my Aristona VHS recorder (model 2SB42/03) is broken. I already bought a new
one but I would like to repair the old one myself.
Is there anyone who can tell me where I can download schematics etc. or

Thanks,
Marc

I've acquired an older Sears brand VCR. Model 934.53520650 The
cassette door says LXI series. There's a silver "Digital" badge on the
L side of the front.

I'm guessing it's 15 - 20 years old or so.

What I'm running into is that thought there are RCA connections for In/
Out L/R audo & Video - in addition to coax In/Out, I can't see to get
it to pick up devices such as another VCR, A digital converter box,
DVD player into the RCA jacks, only through the coax connector. It
will output through the Out-RCA's but so far haven't gotten it to
receive anything through the IN RCA's.

I've fiddled with the Std/CATV switch on the back, the VCR/TV switch
on the front, nothing seems to have an effect. On newer VCR's I've
had, going in to the RCA's is accomplished by selecting "Line" on the
channel selector, but this old Sears doesn't have a "Line" channel,
only 2 - 13.

Hi all,

I bought 3 'used' TEK 2445 scopes ($60 for all) from a local company that
just wanted to clear some space in their warehouse. I was able to get two
of them up and running by swapping some of the components that were damaged.
The third was obviously dropped against the HIGH voltage board that drives
the CRT. Both power up fine now, and one seems to be working just fine.
The second one gives a strange output with nothing connected to it. The
trace seems Ok near 0 on the vertical scale, but if I adjust the vertical
position, the trace get wide, and will trigger a sawtooth profile. The
amplitude for this profile gets larger the further away form 0 I get. It is
too repeatable for noise. Is there an adjustment for this? Or is it a bad
component/board? Any help would be appreciated.

Need information on Ferris Instruments Model 22-D signal generator.
Would like a manual, but specs and schematic would help.

Dear All,

I am looking to get hold of 2 data projectors and screens for a training day
for some students. If anyone know where I might find these, it would be a
great help.
