I have Sony KV-27EXR25 TV. Relay clicks but it is dead. When I made some
search on this model and symptom, I followed all the troubleshooting steps
which did not change anything.  First I have replaced IC651 (STRS6301); did
not make any changes. Then took it to a TV repair shop for

Can the group recommend an internet based supplier of small quantities
of electronic components for hobby/project use?
I don't generally need anything very exotic;  most of my stuff is
audio frequency processing.

I've got a tube of  41HU and 41HW ICs.  The date codes are 1178 but I can't
find them in either my 1976 or 1980 WE data books.  I assume they are TTL
SSI.  Any old Bell shaped heads know what they are exactly?

 For those of you interested in collecting vintage transistors, I have a
Raytheon CK722 for auction on eBay.
Here's the link for those who are interested:

What is JM38510/06001BEA? Is it line driver?
how can i get datasheet?
Please help me.
Thanks.

I bought a bag of 12 Amidon ferrite Beads, # FB-77-6301 so I could
make some more inductors for my V boost circuits.  I wound about ten
turns of 24 gauge telephone wire on one, which is a toroidal sleeve
.375" OD, .194" ID, and .41" long.  I measured the inductance at 405

Hello Group,
not be a repairer, but trying to do some research..
i am trying to locate 2 chips for a monitor
for a repairers in bristol Uk

If so, by how much? Can anyone point me to any info on the subject or pass
on any personal experience?
We can re-layout a board to use an OMRON G5V-2-H-24VDC relay in a normally
de-energized position but I wonder if it's worth the effort.

are there any substitutes for non inductive resistors in the 2watt range

I am having problem finding out if this is possible:
A battery dependent device (5V) containing a microprocessor
and a pyroelectric sensor, in one mode of operation is to use
close to zero (idealy zero) current untill light hits the sensor, at

I have a bunch of thes PLAs. I'd like to access some datasheets, but I just
couldn't find the PLC product family on AMDs website!? Could anyone help me
find the way to the datasheets?
Thanks a lot.

Trying to fix this Sony STR-D550Z AV receiver.
All of a sudden the left channel sounds "buzzy".
Not a hum, but the audio is broken up... sounds like a bad cap.
But in tracing the signal I came across this IC STK350-030 that is running

I'm looking for a manufacturer with experience from the mechanical
parts of turnable fold-out videocam displays or similar. Please
contact me if you know of anyone.

The first thing (don't remember where it come from or it's age) looks very
similat to an regular transistor. The cap is almost an TO-202 but some
smaller. The front side is marked: "c106n RCA HH 8419".
Another one has a TO-202 case, and is stamped "f2r5g"

Over the last few years I've acquired quite a few consumer electronincs pcbs
including TVs, VCRs, stereos, etc, so when I discovered that I needed a
tantalum to repair some test equipment I was going to salvage a tantalum.  I
couldn't find one anywhere, so I assume they're too ...
