Discovery of the day. The $1 special, Lg. sugar free iced coffee from McDonald's becomes a premium drink with the addition of Kirkland Irish Cream. (If maybe not so sugar free anymore)3 points

I bought several options from them for the upcoming furniture. Got to attend a demo at the hardwood dealer and I really liked the end results.2 points

there are many possibilities: for the power supplies first you need to decide if you want to heat the valves up before you apply high voltage. If you do then there are two options. Do you want to implement the delay using a relay (and either switching the ac input to the high voltage transformer or dc output of the high voltage psus) or apply a dc voltage to switch on the high voltage psus? IF you do not want high voltage delay or want to do the entire delay e.g. by timed relay off the psu board then use the golden reference 1.7 series psus if you want to switch on the hv psu by providing timed dc then use the golden reference 1.8 boards. next you need 3 hv rails - two positive (220V and 400V) and one negative (-460V). So you need to look at the options. golden reference Dual boards have a positive and negative rail, headphones bias and a simple low voltages + and - rail on one pcb but are of course wider than a single rail board. or you could go for three single rail separate golden reference boards. boards with left in their name have a negative rail and simple low voltage supplies. boards with right in their name have a positive hv rail and the 580V headphones bias. See https://www.head-case.org/forums/topic/15634-goldenreference-high-voltage-power-supply-grhv/#comment-851207 for board physical sizes. Next for an over kill design you may want to have a high performance low voltage section using a golden reference LV board instead of the basic low voltage section provided on the golden reference hv boards. The low voltage provides power to the dc servo, balance servo and cathodes of the 6922s that the input signal goes into for the delay board you can use https://drive.google.com/drive/folders/1r3g2TAtBUaBdiMorTWX7yYgeJ7maQbYW or use what I use which is taken from a German website: schematic: http://www.high-amp.de/html/reg_pws_v3_add_on_schematics.html gerbers etc http://www.high-amp.de/powersupply_stabil_add_on.rar NOTE the hi amp delay board also provides a dc 6.3V supply capable of powering the 6922s but then requires 2 windings of about 8VAC rms as its input. Or you can just not implement the circuit for the 6Vdc heater supply and run the delay timer and relay off a single 6.6VAC winding without issue - which is what I do (see bellow). If you only implement the delay from the high amp board this is the schematic of what you need: Here is my build with a golden reference HV 1.7 dual and golden reference 1.7 right (modified by me to remove the bias components), and a golden reference lv (the delay board is in the psu box with transformers.). The delay board I designed myself based upon the delay circuit from high-amp. It runs off one of the 6922 heaters and is modified so it switches all three outputs of the HV transformer - which is why there are two relays. It also provides screw terminals so you can attach dropper resistors if your heater voltages are two high. (I like to run the heaters 6922s at 6VAC rms). The delay board I made also provides dc power for the led in the on off switch. Removing the fuse allows you to power up the heaters and low voltages only. The standard hi amp delay board only provides a single relay which can be used to switch the AC input to the high voltage transformer. This mandates the use of two transformers - one for the low voltages, heaters and delay board power and a separate one for the high voltages. My board switches the outputs of the HV transformer and so could be used with a single transformer setup or dual transformers. It also provides terminals for all voltages going to the amp. (I have a build policy that all pcbs and major components e.g. transformers should be removable for servicing with zero disordering - hence the screw terminals added to the delay board.) here is the gerbers for my dual relay pcb with screw terminals: mini t2 delay with screw terminals.zip here are the gerbers for the dual delay with no extra screw terminals for the other voltages: mini t2 dual relay delay no screw terminals.zip2 points

Speaking of finishes, I'm anxious to try Rubio Monocoat. It's a wax oil product that many Youtubers are enamored with. I have to admit that Doug has steered me toward natural finishes. One big benefit being ease of repairing/refinishing such a piece. No need to remove the old finish first. Just reapply and buff. And the dull glow fits my esthetic sensibility.1 point

Yep, though inherent would be closer to bought. Mel's sister gave it to us as she left the country to convert souls to white Jesus. And of course ROI sucks for any other choice when you're comparing to free. Especially during rarely used pandemic times and Mel's Mini is just more fun to buzz around in. #firstworldproblems Grahame, there's actually a children's CD stuck in there, that condenses (shockingly well) the first three Star Wars films down to a softer ~35 minutes using voice actors, half of which seem to have never heard the original actors. The accompanying book is long gone ([ding] "turn the page"], but we switch on every few months, usually at night, for a semi-exciting adventure and laugh. Far worse things to get stuck in a CD player. #firstworldproblems1 point

Was supposed to pick up my new lappy and iPhone yesterday, but an unforscene complication on the other end put the kibosh to that at 9:30 in the morning. Currently everything is up in the air.0 points

RIP to a random person: Krysten Gentile. Krysten died a few days ago, at age 40, of stage 4 metastatic breast cancer. She worked at the same company as my wife Karen; I was able to meet her once when she and Karen had a Zoom call with each other. I poked in and had a brief but very pleasant chat; Krysten's persona - so bright and beautiful - shown through even in that brief moment. A truly beautiful and amazing woman, she fought hard, and was public in her fight and in positive thinking to help others. She created a web site & podcasts with another Philadelphia-area woman with stage 4, "Making The Breast Of It." She touched Karen's life, and even a tiny bit of mine. Obituary: Krysten M. Gentile (nolanfidale.com) And....FUCK cancer!0 points
