Not entirely true. Sitting it on the heat mostly spoils the taste
by burning oily resins that don't get extracted in a cold brew.

Yes. And it reheats better too.

What does that have to do with anything? Those components are only a
problem when overheated. In fact, some people don't care for cold
brewed coffee because it loses some of the taste they are used to. They
*like* the taste of hot brewed coffee when fresh. Cold brewed coffee
tastes almost like chocolate to me... not that I mind that... :)
 
I tried cold brewing a batch here where my water is from a well and full
of various things. It didn't turn out so well. I guess I could use
bottled water. The water isn't an issue with hot brewing.

If you say so.

We did taste tests today.
 
Drinking it black, cold brew was clearly better.
 
But none of us drink it black. My family adds huge amounts of creamer, and I put a tablespoon each of butter and coconut oil in every cup.
 
One advantage of concentrate is not having to wash the pot daily.

It's called "bulletproof coffee", probably because you need a
bulletproof stomach. ;)
 
Popular with the keto diet crowd.

Bought new 2 years ago, now died totally.
Date? 2007 on the pcb overlays but Schuko mainland Europe mains plug
with a 2014 moulding date.
Firstly that line-plug set in an "clamshell" adaptor for the UK , with L
& N swapped over, sprung brass earth used for "earth bond" continuity .
A break in the intended neutral wire somewhere, I originally suspected a
dodgey adaptor. I have removed the cable and break is not at the
so-called "strain relief" grommet. I'll hack into the cable , to
find&inspect the break before replacing the cable, anyone seen the
likes? PbF soldering to the "euro" plug pins or tin-pest "tinning" failure ?
No obvious overheating of the pins in the adaptor or casing or cable sleeve.
 
The internal 20mm 10 amp fuse & holder surprisingly looked healthy
considering the yokes of the holder were only just making contact.
Is it asking too much for 20mm format to carry 10 amps reliably?

Theckhhhmah, you retarded dumbfuck! You're one of usenet's village
idiots, and you just cannot stop flogging the rotted corpse of your
DST hobbyhorse (that's DST; look it up if you have to). But it's dead.
It's bleeding demised.
 
Maybe you can get a grownup to adjust your clocks twice a year, if
you're just too stupid to do it yourself. You keep telling people when
they should wake up and when they should go to sleep. Maybe you should
just worry about your own pathetic life, and stop being so fucking
lazy. Nobody wants to live their lives according to some retarded
schedule dreamed up by a microcephalic dumbfuck like you. Just live on
TDT (Theckmahhh Dumbfuck Time), that's fine, as long as you're ready
and wearing your hockey helmet when the short bus comes to take you to
your job at the hire-the-retard used crap store.

Even better, put the last four digits of the SN on the receipt which they must bring in to get warranty service. In some cases it is on a sticker, in which case you can etch it into something inside the cabinet.

Different market. My shop fixes coin operated amusement machines, hourly
rate is good, and people appreciate us as we are one ot he few
professional shops around that deals with these games.

Other than our customers are mostly private we seem to get a lot of

We keep a wait list (285 folks on the list = bigger shop needed, so
moving this week and next, and have to hire more people) - too many jobs!

I don't think too rare. Much of my repair work is SMD components.
 
Your not going to find too many through-hole components in professional video cameras these days...
 
The same goes for high end touring gear as well. While there are "standard" components, much is SMD these days.

I just hate dealing with customers machines after they use WD-40 as a
'lubricant'. In all cases, after a few years, the gear systems are
frozen with some sort of glue like substance that take soaking in
mineral spirits/paint thinner overnight to soften enough to take apart.

Indeed. WD40 never sets 'hard'..

Anecdote:
 
I bought one of the very first CD players available for purchase in Australia ( Sony CDP101 ) in May of 1983.
 
I still have it and it works perfectly.
 
But after about 15 years, the drawer mechanism became VERY slow and eventually would not allow a CD to be played. The reason was the white grease applied to all the nylon gears had turned into brown glue.
 
I found that some WD-40 instantly softened the grease and operation returned to normal - but not for that long. After another couple of years the same problem returned.
 
So I bit the bullet, pulled the mechanism apart and cleaned all the nylon parts thoroughly - in WD-40. Then re-lubed with Valvoline "X-All Grease", a product intended mainly for marine use.
 
No problem since.

I have an AIWA turntable, model PX-E850U.
 
It needs a stylus. On the label, it says "Replacement Stylus AN-11".
 
I'm sure I can locate a replacement stylus, but how the heck does it
come off? This has me very puzzled.
 
The good turntables I had over the years always had a removable head,
and the cartridge was held in place with tiny screws.
 
I see no way to remove this head, and there are no screws for the
cartridge. I know some of the stylus had a plastic piece that slid into
the cartridge. This looks like it might work that way, but it did not
pull off using light pressure. I know better than to force things, until
I know exactly how to remove it.
 
To make matters worse, I cant lift the tone arm more than an inch or so,
so I cant really get a good look under it.
 
Anyone know how to remove this stylus?
 
Thanks

**Easy-peasy. The cartridge fitted is a standard Audio Technica type.
You will probably find a you-tube instructions somewhere, but the stylus
does not pull out like most. It kinda pivots at the rear and 'clicks'
into place at the front. You just need to pull down on the stylus and it
will come out easily.

My first magnetic PU was an AT66, "induced magnet" type.
 
Bought it at Mike Sheridan's old store in Redfern in 1972.

**Most AT MM carts have two teeny tiny magnets in a 'V' formation. I've
seen a few induced magnet types from a variety of manufacturers over the
years. I think Nagaoka still make a few. Dunno if AT still do them. I
doubt it.
