Another Grounded Grid lives. Have been listening to it for about a week. Powered by the same GRHV/GRLV PSU I use to power my KGSSHV, Carbon and Blue Hawaii. 400VDC rails and 20mA plate current. Using EH 6CA7 - the true beam tetrode not pentode. Runs much cooler than the Blue Hawaii. A tough job remains to drill the holes on the top plate. This is one fine sounding amp!

Some progress. The terrible unbalance was due to an unconnected small tube pin. During the milling process the CNC machine drilled a couple of unauthorized holes which I completely forgot when soldering the board. When corrected the amplifier works. The offset is done by opto servo and it works as supposed. Balance control is also done by servo and I've no trimmer. I've same balance servo here as in my amplifiers with LSK389 input and there it works without any problem. With the tube input you can probably expect more differences between the sides. First tube I tried gave 260 V unbalance (offset worked, so +130V and -130V) and the second tube gave 30V unbalance. The balance servo (in current version) is not capable to make it balanced if the tube isn't enough matched. The input is supplied by +100V/-15 and all components there are surface mounted. Current source is 01N100D/LT1021. GG to the left and tube input GG to the right.

Fired up the vinyl rig after two years - damn I forgot just how great vinyl can be Sent from my iPhone using Tapatalk

Put on the shim and FSA seatpost. Now this bike rides as nicely as I remember the DeSalvo rolling. Shaved a few ounces off from the tree trunk of the seat post I took off as well. Somehow managed to shave 8 seconds off my PR on my neighborhood climb so those few ounces must have been some really heavy ounces. Sent from my iPhone using Tapatalk

happy it works. now for a version with tubes as the constant current sources And a cherub has just informed me a t8000 is headed my way I like retirement. going to a hamfest tomorrow to see what I can find to update some of my very antique test gear

YMMV but me experience with using the Metic Halo UNL - 8 was positive compared to analog phono pre amps in that sub $2k range. Not that some units like Eddie Current's or some vintage units didn't have their appeal but on the whole the MetricHalo held it's ground and then some. I'd like to get back to a tube based phono pre at some stage of my life but for now digital RIAA the mic pre amps in the MH unit are fine. Be careful getting into the rabbit hole of needle drops as I lost countless saturdays to recording, tick and pop erasing, track separation and tagging. Fun but time consuming

Hah. Just realized the easiest way to get Jeff to buy new wheels: "Hey Jeff, I have those Shimano R500 wheels on my bike too!" On another​ note, been a bike heavy day today. Had a swap meet and bought 40$ of stuff for 30$, then went and ride with Xavier and one of good friends and their family. **BRENT**

i also went to tokyo recently, and the used record shopping was even better then i had hoped for! so many shops everywhere! well stocked, organized and best of all, properly graded! surprisingly, i didn't find much (old) japanese music though, which was a shame, as i really wanted some Taeko Ohnuki records (i already have them on cd, but i want vinyl too!) i also bought a AT33 mono, as it was so cheap down there.

Summer time...

Life was getting too easy and comfortable, so i decided to go full retard - tossed the minidsp in the bin and bought an Audiolense license and a lynx aurora 8 channel dac. The Audiolense speaker XO and TTD room correction really rocks, but getting my old surface pro 2 to do live convolution of vinyl playback turned out to be a bit much. so now i need to build a powerful (but silent) media computer to do the maths, if i want to listen to my records... looking forward to trying out digital RIIA conversion as well. (Dac and computer haphazardly strewn about)

Test Tone @ Home is live on the internets right now! http://mixlr.com/illuminator/

This is a timely thread for me too so thanks Posty! I've just sold my duplex in San Jose and I'm heading up to Oregon. I don't have a ton of money (it was a 50/50 split with my sister for the duplex) but I will have enough to buy a small house or plenty for a condo/townhouse. Just like Posty, I was wondering about the noise from and to the neighbors and other "hidden" issues of living one of these. So thanks to all who've posted. These first hand account are fantastic!

Bought a 2 bed/1.5 bath in September. 5 unit building from 1940, full brick exterior. Half our basement is finished and that's where the rig is at. Next door neighbor said she has never heard us, apparently these walls are some kind of magic because we've never heard anyone else either. Most unique thing for us - there's no association at all. Typical HOA would've been $5-700 around here, nice to pocket that instead to use it for what we need it for. The general agreement seems to be that for all our shared spaces, we try to stick together. All of us are using the same landscaper in front, $10 per unit a week and we all pay separately. Two of the units got their roof sections done late fall last year, so we'll just go with the same roofer when it's our turn. One neighbor seems keen on getting everyone involved when doing things like windows to get us all discounts. So overall we have more risk with the big fixes but everyone has been great and we'll just go with the flow. I don't have much negative to say on the building overall. Our only issues are within our space, particularly a crap kitchen but we've plans to remodel within a year or so. Had to drop the coin for all brand new HVAC and washer/dryer but it's been worth it. Best of luck posty, it sounds like a good move!

Crumbs, Aracacha (or peruvian parsnip) pure, Tzatziki, capers and leek deglaze, and a cunk of meat

Marched in the Knoxville pride parade with my family and some local libertarians.

Oh snap, new KSIA.

Very nice Michael!

Beautiful work!

i had no luck in my quest for used carts. i guess they trade them back in for a discount when they are done with them or something like that. lots of other fun stuff though

IKEA bamboo butcher block isolation platform!

Thanks! the chassis is BZ3608A I purchased from TaoBao. Also available on eBay. It should fit the Megatron fine except you don't need heatsinks for the Megatron.

Every time the brisket fairy sheds a tear someone wants to use it to boil a brisket. It's a self-fulfilling abomination. Sorry you had to see this brisket fairy!

What chassis is this ? very nice the chassis look to be fitting Megatron just fine ?

155F/24hr/lots of salt and pepper, oven at 300F for 2 hours on a wire rack.

I love the groove of this one:

Fuck it. This. Is. HEAD-CASE! Maxxed out it is.

My general advice to anyone is to get the highest end model, whether you need it or not.

Sounds like work.

Open baffles do things box speakers don't. Of course they need extensive EQ, but one of the things you notice if you are used to box speakers is they can sound bass-shy. If you are used to open baffles, or electrostatics, of planar magnetics (Like Magnaplanar) there are no surpises. The bass is there in the right proportion to the rest of the music with no overhang, and sounds tight and fast. And open baffles interact with the room in a completely different way, exciting far fewer resonances. Well you can buy a kit, or even buy one already built. Or you can do what I did - buy two sheets of Baltic Birch and build them from scratch. Then hot hide glue veneer them, and French polish them. Parts which are not veneered I made from a Rosewood called Cocobolo, and the feet were made from Goncalo Alves.
