Nice case! They look nicer in your picture than on the website. Hopefully I can find a decent enclosure locally.

luvdunhill and I will be spicing them up with wood panels in the recesses. Probably a nice Rosewood for me, and Pine for luvdunhill.

Just kidding Marc.

dude you totally blew your cover.. anyways, just give them a call and order on your own, or go with the case that DigiPete is proposing.

one brief update... after a small embarrassing mistake, I stuffed 6 boards this weekend with the required resistors... according to Mikhail's math, this should be perfect for a Quadraphonic setup. Anyways, couldn't help myself...

The plan at this point is to work on matching the Toshiba transistors and then if I haven't heard anything from Digikey by Wednesday, just go with the slightly higher tolerance capacitors and be done with it. I hope to get the parts by Saturday, if I play my cards correctly.

I'm hoping you'll have your kits by sometime next week.

oh yea, I kind of forgot..

Thank you for your suggestion. I'm talking with a local DIYer and he might be able to reccomend me some local stores with enclosures that could work. Building a stereo phono preamp requires precisely matched parts so I should be fine with the kit you're putting together right?

What table are you going to be using Nenso?

Ping pong.

I'm working on it, still don't have a vinyl rig yet.

A Pro-ject Debut or something else like a Music Hall MMF 2.2 might work for me, I'm not sure/not there yet.

Ah the old cart before the horse trick. I've been there.

so, the 1% TH parts are being discontinued by Panasonic in favor of some 5% SMT parts... lame.. so, the substitute for P3884-ND was P3931-ND which are 2% parts and I added an extra 50% to the quantity to give me a few to match with. The order is being filled at the moment and I hope to have the parts and the kits shipped by the end of the weekend.

To answer Nenso's question, I'm probably not the best person to ask if the parts chosen are high quality and well matched, as I'm putting the kits together. Of course I think this is the case

I will say that this project should out-class everyone's table/arm/cartridge on this thread, mine included, and I can let you know how it compares to my Xono.

UPS is estimating Monday for delivery of the parts, so I may be a bit later in sending them out. I'm not sure what I did to anger the gods, as Digikey has always basically been "next day" to my house, no matter the shipping method...

The Gods are a fickle bunch my friend.

they indeed are... today the parts arrived.... a lot of parts... then I figured, screw you guys I'm going to go work on my own projects and pack this stuff later... then my heating element went out in my soldering iron

But they seem to have a sense of justice. Maybe not. At least they have a sense of humor.

Yes, God sent you a message after the 'screw your buddies' thought came into your head

problem is I was working on moving my JFET matching jig from breadboard to perfboard, and making it where I could match 4 devices at a time... so, kinda bad for you guys too

Darn the sword cuts both ways

I hope you guys can take some pictures of your building progress.

sure, I'll try and document things...

I'm done counting out most of the parts. The caps larger items are proving quite bulky to pack. I'm going to go to the post office and get some flat rate boxes tomorrow, as these kits definitely have some heft to them.

Awesome Thanks again for doing the group buy.

Does anyone know if the gain is adjustable on this phono stage?

Also what are the 9v inputs for (battery powered mode?)

Nope, not without doing some serious recalculation of most of the resistor and capacitor values.

The 9v battery inputs look to me like an optional replacement of the 1n4739 zener diode, for if you have objections to these parts. This is used as a voltage reference for the regulator. That said, this is just my guess looking at the schematic, which doesnt make it clear.

yup, the battery is used as a reference.

Anyone doing dual transformers in the PSU?

Or any other trick mods?

yes, there are 2 people doing dual transformers.. me with the ghetto ones from surplus sales that are posted in this thread (still haven't figured out which set of wires is the primary and which is the secondary) and swt61, assuming he can shoe-horn 2 donuts in the case somewhere

trick mods? hm.. you could look at lowering the JFET degeneration resistors and playing with bias points... perhaps add a choke in the power supply somewhere... uh, I dunno...

I opened up the CIAudio VPP1 phono.... two opamps.... still sounds pretty good.

I hope this one sounds much better
