Is it still possible to get boards for The Wire?
I am waiting sooo long without a hope to receive the answer.
Regards.

Hi Guys!
Well, it has been a bit of a hiatus, but I have had a much needed break to focus on family, work, travel and a few other fun projects, many of which are audio related.
I'm still trying to find a way to share these projects in a more consistent way with the community at large, without tying up all my time managing the orders, packing and shipping things. It's still a work in progress, but I'm getting there. Until then, I'll keep running the order system as-is.
It all boils down to the fact that I love making new designs, I love testing them, and I like sharing and making the boards available. I've been thoroughly enjoying a few of my latest projects, and I figure it's time to start getting them posted here so others can as well.
Here's the update, and the order of events:
1. I will send out payment requests for all new SE-SE, BAL-BAL, PSU, LPUHP and LME AMP order this evening. These are in stock, and ready to ship. My apologies for letting the orders pile up!
2. I have all the NTD1 V3 and NTD1 V3 PSU boards ready to ship. Some of the orders for these boards are very old indeed, but I'll send everyone a payment request, and if you no longer want these boards, then please delete your order on the order page. Expect a PM tonight or tomorrow. Details (BOM and schematics) for this project will be posted over the next few days.
3. I have four really fun new projects to share over the next few days, and the boards for these are already in-house, so orders can be accepted and filled immediately. I will introduce each project here, and create a separate thread for each. They are (in order of my excitement about them):
- A very high power, very low noise, regulated power supply for almost any power amplifier based on 4 parallel LT3081 regulators per rail. It provides a very robust 8A RMS of continuous output current at up to +/-34VDC. The outputs can also be tied in series to provide up to 68VDC @ 8A. I've used this to power all sorts of amplifiers including a pair of F5 amps I still had around. The performance improvement over an unregulated supply is amazing.
- A fully balanced 3-stage ultra high performance phono preamplifier. This is an all-in-one PCB with an ultra low noise supply based on the LT3042, and using LME49990 op-amps with a very accurate passive RIAA filter. I use mine with a Denon DL102 and 68dB of gain.
- An ultra low noise bipolar power supply based on 4 parallel LT3042 regulators per rail. This is intended to power the headphone amps, but could be used for anything requiring up to +/-19V at 800mA. It's "performance first" approach to power supplies 😉
- My take on a bridged "composite" amplifier using a pair of LM3886s per channel nested in the feedback loop of an OPA1632. The original version using the OPA549 was a total flop, so I went back to the drawing board and tried with the LM3886. This time it's definitely a success, and a pair of these provides a lot of output power (140W @ 8R) with very good performance and extremely low noise. I designed the above mentioned high power regulated supply just for these amps, and they work very well together as an easy to build system with exceptional performance.
More details to follow, and keep your eyes open for a PM tomorrow if you've been waiting on the NTD1 boards!
Hope everyone is well, and thanks for the happy birthday wishes! I spent a very fun day driving several exotic cars around the Niagara Region with my Dad 🙂

Hello Owen!
The price for NTD1(20$) and NTD1 PSU(20$) is for the bare boards or fully assembled ?
Some time ago you were talking about Reidon Thin Film parts from the PFS35 series of resistors which I want to order from you too. Are they available?
Thank You
Please do not forget about me, I want a set of those boards too!

cool! i have also been waiting a time for this.
so i wrote my name in the spreadsheet linked to in this thread:
The Wire - All Boards and Kits Explained Here! - diyAudio
is that it? or do i need to do something else?
btw, does anyone know how to get a parts kit in europe (austria)? all i know is conrad, and it is quite bad...
thanks owen!

Hi tituman,
For parts look at Elektronik und Technik bei reichelt elektronik günstig bestellen or Mouser Electronics - Distributor elektronischer Bauteile
Here in Germany they are very reliable.

Hi! Owen,
Any tip on selecting the MOSFETs for NTD1 V3?
I am interested in passive RIAA also.
Thanks!

Im having an issue with the BOM - NTD1 V3
Reidon
PFS35-390RF1-ND
696-1281-1-ND
They only come in 500pc rolls.
whats plan B?

Hey Damuffin!
Hope all is well with you!
I believe OPC was going to offer them to buyers of the V3. I would ask him if it is still the plan.
Let me know how you like V3 once completed. I'm still running V2 and really like it.
Ciao!

Hi Guys,
For the Reidon resistors, there are many equivalents. I'm out of town today, but I can post a more comprehensive list tomorrow afternoon.
Look for DPAK parts from:
Reidon
Caddock
Bourns
Ohmite
Vishay
Here are a few part numbers:
PWR263S-35-2000F
PWR263S-20-2000F
PWR163S-25-2000FE
MP725-200-1%
WSMHP35-200RF
WSMHP25-200RF
TDH35P200RJE
PWR263S-35-4000F
MP725-400-1%
I used the Caddock MP725 in 200 and 400 ohm in my build. Both are in stock at Mouser
I would love to organize a GB for the Reidon parts as they are the best suited, but we need enough interest to get at least 200 parts.

Owen

I guess there is always the direct approach.

Digikey has:
Ohmite TDH35P200RJE for $8.30
Bournes PWR263S-35-R500F-ND for $3.65
Thanks pinnochio, all is well. It looks like you've been busy collecting some new toys. I am watching.
