We're going to go thinner with the Hammer!

A tonearm board.

Not to mention the resident Mather...

Still need to run them rough the sander. Goal was to have them be 1/32 when finished. I’m sure I could go thinner but wanted to err on being thicker until I’m really good at resawing them.

Marc sent me a really nice piece of figured walnut to turn into record player parts. Part is going to be 1.35” thick but board was 2.5”. Seemed to be a waste to machine/plane it down to the correct thickness. Nice finally having the right tools for the job.

time to get out the dca75 and dy294. Your photos look consistent with my known good from mouser. If they are fakes they are extremely good.

I was wondering what you meant by that. Figured it was something personal, but clearly lost on this camper. Good stuff, ER. Enjoy it in good health! HS

starcat THE EBAY TRANSISTORS LOOK FAKE the sellers negative feedback is also full of warnings of fake transistors, not as described, measured and out of spec, arrived not working etc etc. and many many cases of just not shipping anything at all. My known genuine have: 1. numbers and letters inside the circular indents. there should be left circular indent moulded words china and a single letter code, right circular indent a three digit code again moulded in my case 1 letter followed by 2 numbers. 2. all text should be moulded not printed or etched 3. the manufacturers logo is different 4. the main writing on the lower half of the body should be inside a indented rectangle. All of which agrees with the photos in the posting from John just above and is significantly different from the ebay listing you link to. Production may have changed over the years but I highly doubt the ebay devices are even cree. To attempt to determine if genuine. least reliable visual inspection of case, markings, <- some what reliable but production markings change over the years and some are easier to fake than others. However some fakers are so lazy simple things like the length of the pins, shape of the case are wrong. But the more practiced fakes will take another device with the same case and legs and rub off any markings and print new markings or laser etch new markings. I don't think many if any fakes would go as far as to remould cases. better visual inspection and then transistor identifier like a peak dca75. can identify pin out and type but not breakdown voltage which is important for power supplies and valve amps etc. I have received fakes that don't even have the correct pin out or are not even the correct type e.g. npn when they should be pnp etc etc. But again the more experienced and more prolific fakers will at least provide a fake with the correct type and pinout even if the breakdown voltages, wattages etc are very different. even better a device capable of testing breakdown voltages like a DY294... can provide breakdown voltages but not characteristic curves but this would not necessarily spot a fake that has similar pin out and breakdown voltages but wildly different characteristic curves. even better proper high voltage curve tracer and measure against spec sheet curves and or a known genuine parts P.S. I have reported multiple serial transistor fakes to ebay and ebay do not give a damn. I have tried explaining that not only is it fraud but the voltages involve constitute a potential risk to life and fire hazard... ebay don't give a damn. I went to pay pal... don't give a damn. The issue is many people don't realise about fakes and if they buy and don't test or use them they will probably leave good feedback about the transaction reinforcing the sellers reputation.... I fell into this trap myself when I first started I just did not know about fakes. As an experiment I even purchased over a period of more than a year a few transistors of the same type from the same seller and every time they were fakes. I used ebay returns each time providing evidence from the DCA and DY294 that they where fakes and the seller continued to sell the same fakes year in year out with no problems. I bet they even resold the ones I returned.

Teehee... I was kind of thinking this was completely out of character for James. Meanwhile I bought some C2M1000170Ds from eBay and kind of resigned them to be fakes... They’re looking a bit beat up from being jumbled around, but I think the gamble paid off.

Flippin' awesome! That is such a game changer to be able to resaw to that thickness!

If the rest of those shows cost $200M and flop like Jupiter did that universe will be DOA.

You are not supposed to drink the motor oil, Steve.

If you check the revision number and file properties, the datasheet from Mouser is from September 2020, and the one from GeneSiC direct is May 2021. It also seems that in the new datasheet, current has been de-rated. Whether it was a mistake on the datasheet, or a change in the part...? Either way, I certainly wouldn't put it in a board without testing it first! [EDIT] ninja'ed by jamesmking's edit!

I thought I was going insane. Here's the data sheet from mouser: source and drain are reversed compared to your datasheet for the same product also the current ratings are different WTF GeneSic..... https://www.mouser.co.uk/datasheet/2/169/G3R450MT17D-1919148.pdf

Spent the day on the bike followed by a little kayaking. Went to copperhill, tn on the bike.

The rules of Spoiler Avoidance may be mankind’s greatest mystery. On the subject of mysteries, watched a bunch of these this morning...

Kind of spooky or a lot of spooky? Looks interesting but sometimes I would rather torture myself with racing vehicles that are far to heavy and illogical vs scaring the crap out of myself....LOL HS
