I've recently had a few cases of ceramic discs - usually 0.1µF used for HF
smoothing - failing short circuit. They've been generic wax covered beige
coloured types. Any better replacement  - or particular make to go for?

This unit, TEAC PD-D850, is having difficulties playing audio CD-Rs. Not
every CD-R has
problems, only some of them and the problem consists in not locking into the
tracks. The strange thing is that the CD-Rs are all of the same brand, same

My shortwave radio receiver's speaker is dead (Hallicrafters Model
S-38). I can't find an exact physical match to it in the original 16 ohm
impedance but can match it with a 8 ohm one that has the same mounting
pattern.

hey, I've got what appears to be the following, according to windows:
HL-DT-ST DVDRAM GSA-4082B
basically, its a dvd+rw drive.
anyway, the problem I'm having is that every so often, it simply won't

I have a Montgomery Ward model GEN 12394 14" color TV made during
August 1983. Recently, it intermittently fails to stay tuned to the
selected cable channel. During this intermittence, it appears to
switch to either channel 2 or 3 regardless of the selected channel,

I have a monitor here, I've had it for probably about 4 years now.
Great monitor, perfect color, just the right sharpness, everything is

We just got a new Plasma TV last night. We had the TV on for about 5
hrs and then turned off and went to bed. There was a strange glow on
it. I thought it was just the electrons going down the energy levels
and emitting some phospherescence or sthng???

We see a lot of stuff on here from time to time, about crappy Chinese goods.
Well, a couple of days ago, my usual office supplier sent me one of their
regular e-mail fliers, on which was a high-back padded leather swivel chair
with gas lift, castors, arms, rocker action and so on ...

I bought a used Philips 109B.

is black.
What could it be? A condenser?

I have a transistorized Toshiba 19" color TV that I purchased in 1984.
It has worked quite well over the years, but recently has been
exhibiting a symptom which I would describe as a horizontal "bleeding"
of color under certain conditions.

At AU$24.50 including GST, it looks like a closeout price.
Unfortunately for most of the world, you have to purchase it from
existing stock at one of a very small number of  Dick Smith
Electronics stores in Australia.

Got a call on this Sony rear projection TV Model # KP-53XBR25. Most

About two inches on each side
