Spent the entire day moving houses. Another day or so tomorrow and we'll be set (other than a fridge where I screwed up and ordered one that was too large) Sent from my SAMSUNG-SM-G890A using Tapatalk

suggest you build the kgsshv-carbon first. do it as 2 chassis leave extra room in the power supply for a filament transformer and extra pins in the connector then you can build the GG as a second amplifier and use the existing power supply then even later you can upgrade the GG to DHT tubes simple

Happy birthday Graig! May your foils last longer

Royal Blood -- How Did We Get So Dark?

Happy birthday Greg of the Snakes and Sauv Blancs! Cheers!

Thanks everyone, I feel the love! Spent the day tuning up Lance's gear and weapons in preparation for the Salt Lake City rumble. Later we will go out to a club in Culver City to hear some friends playing in their band.

I never had troubles with the HV900's, and haven't had any that blew, so the following is based on what I've found useful troubleshooting/checking the regular Golden Reference HV. Often it can be helpful to work at lower voltages when trouble shooting. Paralleling the high resistor (is it 2x 450kohm in the HV900?) in the probe string to get the circuit in action at a lower output DC. If regulation doesn't work for some reason and things go bad it usually isn't really bad. Parallel the R8(2x 450k) with one ~100k (one across both) will provide some ~100VDC. Initial check: The CCS's Use a lab supply at some ~15-20V, through a DMM at mA: put the (+) at the drain (middle leg) of the 10m90, and the (-) at the bottom of the CSS where R2(100) and R1(4k5) meets ...you should get ~2mA ....if you see much more, try replace the DN2540. Do the same at the other CSS: (+) to drain (middle leg) at the 10m90, and (-) at the bottom (pin 6 at the voltage reference) ...you should get ~1.3mA ...if not the 10m90 is probably damaged. Check the current limiting CSS you added (your drawing) the same way (Kevin suggested 50mA for this) When powering up the supply, hold the variac when you reach some ~40-50VDC output, and check: the pin6 of lt1021 against "ground" (pin4) ....you should see 10V ...if not, the lt1021 has probably gone south Before raising the VARIAC further: Attach a DMM across the 2k at the bottom of the cascoded CSS ... you should see ~0V (when at ~50VDC output) and only before regulation kicks in, the voltage jumps to some ~4V; it happens just before you reach the desired output voltage Attach a DMM across the 3k at the source leg of the output CSS (right most leg) ...should be some steady ~4V

better to move your counters than to have a too small fridge

I love mine. Don't know about the earlier pre-production models but the one I have exhibits only a slight "closed chamber" soundstage, what I mean by that is that you will immediately notice you're listening to a closed headphone if you came from living with a great open one like I did, or you compare side by side. It is, imho, not distracting once you get used to it. That is a huge praise for a closed can, as I've never heard one I even really liked before. But just like Tyll put it, with the foam inserts these are darn well balanced with controlled bass and no immediate annoyances anywhere even as you go up in the treble. Just a very nice, "right" sounding headphone that also happens to be really solid and lighweight. It doesn't resolve quite like my STAX but because it isolates well, it brings out details in low-level ambient noise that would easily be obscured with the STAX. It's nice to sit on the balcony in the summer and get some sweet tunes. Not that we get much of summer in Sweden...

The filling is decidedly un-empanada like. Lamb and potatoes, and so much the better for it. cf https://www.thespruce.com/empanadas-and-cornish-pasties-3980188

That looks suspiciously like an empanada. You're not going native on us are you G?

Ok Donald

The whole thing somehow looks much better to me with the tubes in. Pictured are the fat bottle EH 6CA7.

A box arrived, today. The case work is gorgeous.

Well I've reflowed a bunch of joints (probably more than was needed). Since then I haven't had problems with oscillation, excessive offset, etc. The sporadic noise seems to have gone as well, but of course just as I say that it'll come back to spite me. Anyway, thanks for the help. I think I can stop fucking with it and just use it to listen to music.

Round a Brit friend, so roast beef Joanne provided the veggies And there were proper roast potatoes and homemade Yorkshire puddings Followed by a familiar dessert
