Inverse RIAA filter (have some extra PCBs, if anyone is interested)

Just Vf - it’s a voltage reference.

I think there is a place for something like this, but for me it would be an active crossover which would have a lot more flexibility.

Thanks. So, the trade value is a good bit less than that, say $200. Ok; will do some thinking

They would be part of a trade deal, so having to put a price on them. What would you expect for example a Samaroli Caol Ila 1998 Vintage (“Singles Collection") to go for? I could use that to tease out the street value of the rum. I haven’t tried any non HC Cuban rums, both Samaroli and Cadenhead seem to have some.

Mikey, any experience with the Samaroli rum series?

The AppleTV update is similarly fun. Posting, or un-posting?

Re-reflowing a part is very hard. Sadly, I have thrown out more than a few of those same regulator packages. Once the board isn’t completely flat it’s very hard to get things rectified.

I will defend this one as I do it a lot. Picking JFETs that don’t need degeneration is optimal. It’s done in more than one commercial design as well, such as the First Watt J2. Now, the other shit I can’t defend

Not exactly sure. He said it real quick in passing. I should investigate!

Actually; the new production Silmics are crap. As mentioned by Wayne at Burning Amp this year

I am using 2SJ106/2SK208, BCM61/BCM62, PHPT610030-series. The 2SJ106 is the SMT version of the 2SJ103. The 2SK208 is the SMT version of 2SK246.

I did fix the silk screen on the new ones

cspirou: I would add an input resistor to ground as well. You can match Q1 to Q3 and Q5 to Q7, but I don’t think matching is all that useful here. If you want to try another small SMD buffer, let me know. I have just ordered some boards now that I have verified their performance versus sims. I can include matched Toshiba JFETs and the other dual package BJTs are available at Mouser.

My Intel NUC also has USB-C video output, so all would be good if someone made a switcher

Recently bought an LG Ultrafine 4K Monitor which uses USB-C (one input and three output). I am curious if anyone makes a KVM with -C output (can’t find any) or what the options are to do input switching on this monitor?

So, what do you guys think of my front panel layout? I would like to loose the indicator mark on the knob, but it functions in four positions alternating between the four options on/off for gain (high and low (MC/MM) and rumble filter (on/off). The LEDs are bi color green/red, green is on/MC and red is off/MM. The power LED is always green. Just using the same value resistor for both colors, they seem to be matched somewhat. The LEDs are from Bivar and the circuit uses one common-anode and one common-cathode. Just for Nate, I avoided blue

I can’t unlock my phone without my prescription glasses. Not the answer you are looking for, but I would assume if you train two faces, with and without, it will work just fine.

Happened to me as well. Took a week longer than the original delivery date but it arrived.

Man I hate casework. I cut this one just a little two close.

Listening is over rated. You need more test gear!!

HC Approved cables FTW!

It’s a good thing Al. Case in point: Old Cohiba band sans holograms - old and antiquated.
