I am currently (as in: the last few months, more intensely this last few weeks, evenings and weekends) working on a Luxman LV-117 amp that, for lack of a better description, is An Utter Mess. Straight from the factory, the wiring is an utter rat&#39;s nest, with at least 30 board-to-board cables going every which way through the amp. The main board alone has _another_ dozen wires on itself, point to point. Mechanically, removing some of the PCBs means disassembling the entire chassis. On...

RE: https://mastodon.social/@zep/116906790195674278 @RefurioAnachro I am sure you could make this a lot more psychedelic and/or fractal :D

WTAF, @Vivaldi ? I thought you were better than this.

I have very conflicting feelings about this :D #electronics #repair #righttorepair

#nowplaying blockhead - Music By Cavelight I always find it hard to classify this. Is it hiphop? Yes, here and there. But also Downtempo, but neither of them exclusively. What it definitely is, is enjoyable. &quot;Good God Almighty, all that other bullshit is here today and gone tomorrow.&quot; #vinyl #vinylrecords

Dear #fedi, I am in the market for a laser cutter. I would mostly use it to cut PMMA. I have some previous experience with a rather large unit at a previous employer, but I have no idea what manufacturers to avoid etc. I don&#39;t need large work area, maybe A3, though A4 might work. Outside size is a bit of a concern as I don&#39;t have a large amount of space. Ability to cut metal would be fantastic, but that can be a later upgrade. #makers #repair #righttorepair

If you&#39;re a graphic designer for the packaging of #vinylrecords and you decide to maximize the difficulty of telling side A from B, or which record is which in a set, you need to stop trying to be so clever. Tiny fonts, not labeling anything, obscuring text by visually noisy backgrounds.... I could go on. Please don&#39;t do it. It&#39;s not clever (it&#39;s annoying), it&#39;s not novel (it&#39;s been done), and it&#39;s not proving anything except that you hate...

I don&#39;t often send my #vinylrecords through the wash, but when I do, it&#39;s usually worth it :blobtonguewink: I don&#39;t use the official Spinclean method/chemistry to wash them, but my method seems to works at least as well --- and is cheaper and less tiring. #vinyl

#nowplaying Fila Brazillia - Maim That Tune One of the first albums by FB that I came across, mostly intrigued by the title. It&#39;s got some excellent grooves and delightful tunes. #vinyl #vinylrecords

Memo to self: if your Bode plots make no sense whatsoever, make sure you&#39;re using the _tracking generator output_ of your scope, not the 1kHz square standard-gen 🤦 #electronics #repair #WerMisstMisstMist

Well, the diff-pair/VAS on this LV-103 is doing some wild stuff. The output of the power transistors (Y) slams first into the negative rail (~7s), then the positive (~7s), while the feedback circuit (R) lazily tries to steer it back to zero. Meanwhile, the protection IC (G, HF-looking noise can be ignored) is just puzzled (as am I) but eventually clicks the relay on. Now the question is: is this amp designed this way? 30s to stabilize seems long... 1/x #electronics #righttorepair #repair #hifi

That moment in the middle of an #electronics #repair when you realize you forgot to order four components, you definitely won&#39;t get them before next week, *and* you will have to pay extra for shipping because the product value is so small *AND* you can&#39;t continue with most of the repair since otherwise you&#39;ll have to take everything apart again once the components arrive. Sigh. I have a _right_ to repair, dammit! ;) #righttorepair

This Matsushita capacitor is ~50 years old, and should be 47µF/25V, as labeled. Its actual capacitance as measured* is almost 78µF. Yay free extra capacitance! And even the ESR is low! * Measuring capacity like this is not the same as &quot;this capacitor can perform like this at the rated voltage and other specs&quot;. In this particular case, due to being out of spec and the reputation of these caps (they are leak-prone), it will have to be replaced and recycled. #electronics #repair...
