I have a Sony VCR model SLV-EZ8 which is about 6 years old. Its a 6 head
hi-fi unit.  Recently, the sound on recordings made with the unit, have a
strong phasing effect during playback. It seems to be worse until it tracks
and at times the phasing is only slight but there is an ...

   I recived a JVC XL-V250BK CD Player for free but the person said it was
not working so I opened it up and the first thing I found was it was missing
the fuse. I was wondering if anyone could tell me what size fuse this player

I have a fair background in resurrecting VCRs, TVs and computers, but I
have never really tried my hand at DVD players.
My friend gave me a DVD player to repair, and I thought I would bring
this by you all for some hints, and maybe even a diagnosis.

supplies.  After soft shutdown it won't boot again unless the PSUs are

How do I enter the service mode on Panasonic TX-32PK25D TV?

I have a truck repair manual on  CDR which I've used only a dozen times.  I
didn't make a back up as I use this infrequently.  No visible defects except
for possibly a small "bubble" next to the spindel hole and well inside the
data area.  Otherwise, seems clean as a whistle.   ...

This question pertains to a Sony GRX560 notebook computer with a defective
SODIMM socket.
The condition only affects chip select (chip present?) at boot time.
Specifically, in order for the system BIOS to scan the installed memory

need a low noise op amp similar to the TL082. It must have similar
