Hi from izzy wizzy

I've enjoyed hanging round here for a bit and enjoy this section very much so here goes.

Came across hifihaven as about every year or so I go scouring the net to see who is building phono stages; my obsession. Came across a build thread with @Salectric and his version of something similar to mine developed over the years being built by some round here. Love a build thread and got hooked.

So here's the room I'm lucky to have pretty much to myself unless we're elsewhere and then young humans invade to watch TV.

Speakers are Tannoy monitor gold 15s in corner York enclosures that were only meant as a trial and here we are 15 years later. Amps next to them a GM70 4P1L push pull.

More to follow.

The rest of it here is Teres TT, Tonearm is a Triplanar, cartridge is a Hana sl.

To its right is phono stage, line stage then phono PSU. Some records here with a double layer IKEA expedit on another wall for records. Tucked behind is a rpi used as a streamer.

More to follow after dinner.

Teres TT was a kit of parts I picked up when in Boulder years ago. It runs with a modified motor and mylar streamer belt. All sitting on a sandbox. Triplanar was once in a lifetime buy for me. Used to make my own arms but then this came along. Cartridge, Hana SL is a recent purchase as had Denon 103 in panzerholz body for years.

More to follow.

Next Round Is On Me
Welcome again and love the wood/casework on all your units! Beautiful And very inviting room.
 
I'm not very good at cases. Mainly because things rarely get beyond advanced prototypes on wood; breadboard. So I just stick them in boxes in complicated ways so I can get them out again whole to fiddle with. This is going to change in the coming year as all the cases are going to be upgraded. Current boxes are things I found at a DIY store.

I'll start at the neatest one; the phono stage which slides out with everything ready to go. It's mc step up d3a passive eq 5687 tx balanced out. Everything is balanced differential from here.

This one is the most embarrassing. I have no idea how it is so quiet.

It started life as a passive line with Sowter TVC. Then made a headphone amplifier on another breadboard based on Lynn Olson's raven using 6N6P so a single differential stage. It all worked out so then jammed the whole lot into here, an IKEA box. It now is the line stage too with the TVC as auto formers on the output.
 
Amplifier is PP 4P1L GM70. Inspiration was Lynn Olson's Karna/Amity.

Again, it's breadboards but it's so heavy, it's built in two halves. Top is all audio and filament supplies. Bottom is separate supplies for finals and front end with plug and sockets to connect together. To keep everyone safe, vented ply panels screwed to the sides keep fingers out. It is of course on casters. Aim is to make it much slimmer on its rebuild.
 
Man, I love this thread! Great system, @izzy wizzy !! I love the mad scientist look of your circuits, but its obvious that there is nothing haphazard about your implementation -- it's all very tidy looking on the whole!
Thanks. Funny you should mention the mad scientist thing. A musician friend of mine calls it the WSP - weird science project :)

Gotta be the pink clip lead! :)
Well spotted and yes, it hums like mad without it as it earths the streamer input. Gotta have a clip lead somewhere otherwise I'm done and then what?

Very nice Izzy! Yes, it does have the "mad scientist look" but at the same time it is practical, logical, functional, adaptable and safe.

I gather this is a more mature version of the amplifiers that you once described to me as lying all over the floor where you literally would step into the amplifier to make changes.

Thanks and yes, an early stereo version is on Lynn's site down the page Grand Aurora
