Leaving the amp on 24/7 Is it ok?

astroglide59: Ever looked at what Audio Note charges for repairs? -
I prefer the K389.

So, if anyone is interested in some of these micro 11-turn trimmers I have decided to go with a different value and have a kings' ransom of 50 ohm left over
-
I suppose calling them "eneimas" might be close of a trademark violation to the reality of Mikhails's "enigma" cable design.
-
I failed at cutting a round hole. But it works well enough.
-
Actually I will get these made for me, but need to validate a few values. It was a pretty quick job, much faster than doing it by hand. a plate wasn't viable because there are parts on both sides.

(makeshift board heater) Then there were three. Now need a jig to be able to apply the paste to the bottom side - perhaps a piece of plywood with a cutout? As you can see, the middle pin of the transistors and the tabs wouldn't flow. These are multilayer boards with that large copper area exposed. I also had to "reheat" the boards during the process. I am not confident I really got good contact on the j-hook trimmers. I will just apply hand solder to these parts likely.

Torture Devices - Do as I say not as I do

Interestingly, the unit came from Japan and they don't connect the earth pin at all. I figured I would do that at some point. -
Looking to buy a used pair. If you have any leads, please let me know!

... Need to catch back up

Ever made something real quick, going against your feeling that it might be a bad idea? Here is one I did today. It isn't as bad as it could be - it was plugged into a fused variac - but still...

I believe the old thread is gone, so starting a new one. A retrofitted power supply for a JDM Esoteric SACD player

Yeah, there are a few cracks that I would like some advise on dealing with. I am thinking maybe a thin epoxy? I watched a few videos on fine woodworking about the approach for knots and other types of checks, but should consult real expert on the matter. There are four checks in this picture.

Still playing Shogi. Need to talk to Dr. Wood though about some repair though - certain wood probably belongs in a more humid Japanese climate.

I am not a big chronograph guy and definitely wouldn't strap anything on the size of 45mm (hey now).
-
That stuff is awesome compared to the barium (sp?) contrast stuff. Plus the one I used has a punny name - GoLytely.

It doesn't make the decision for you, it helps you arrive at a decision.

Larry, what are more well-known GPS watches out there? I am interested in what you have found.
-
It's quite simple. Look at all the values in the schematic and look at the wattage rating. Is 300v across a resistor even possible?

I like the Omni* stuff for Mac. -
It's not needed if you sell and rebuy at a sufficient rate.
-
Very nice. The dimensions are "close". I will try and order some and then if needed incorporate them into my board respin. Thanks! Edit: and bought them all
-
Looks like these Toshiba MOSFETs won't fit a #6-32 screw (I had to drill them out slightly). Is there an equivalent part to these Aavid heatsinks that accepts a metric screw? Any other ideas or similarly sized heatsinks?

The new pre-aged Cubans are rather legit. Perhaps we should organize a box-split
