Great guys, thanks. I had been getting lots of mail about them and have a list of folks that wanted them so I am getting a batch or 75 whipped up !! Cool

They will be shipping definitely by April 15. I will announce it anyway.

Very excited for this! Having missed out the last time. I'm almost sure my name should be in the email list.

The NEW SN Voice boards have been ordered and will begin shipping earlier than expected. Shipments can begin as early as April 6, 2009. I have made some improvements to the board such as wider traces and a large ground plane over the entire solder side of the PCB.

Anyone interested can order now.

Thanks
Bill

um... I want one. Can never have two many SN voices... I was just thinking I'd like another.

Whilst waiting for the board I've ordered to arrive, I've been chasing down the components for this project (Yes, yet another project - why have four projects when you can have five Wink

).

I have identified that one of the key components to source for this project is the 2K 3500ppm tempco. There are quite a few comments in the forums about tempco's, including making your own from SMD's, but I would personally prefer to go down the route of buying ready made components for now.

The first source (which has been mentioned in the forums before), if a little expensive, is at the MFOS site, here:

http://www.musicfromouterspace.com/analogsynth/TEMPCOS/TEMPCOS.php

Next is from the "Others" section of the Elby Designs shop, here:

http://www.elby-designs.com/shopping/index1.html

And last but actually least is the the Magic Smoke Electronic site, here:

http://www.magsmoke.com/tempco-resistors.asp

I don't know if its just me, but the last one tends to keep it in the Thomas Henry family in a small way.

Now the only thing I have to avoid is collecting more projects as I visit these sites (If you're paying postage anyway....). Very Happy

Regards

Thanks for posting the list of sites that sell the TEMCO. Another question I get often is "where can I get the LM394 matched transistor pair?". Futurlec does sell these for $1.80 each:

http://futurlec.com/cgi-bin/search/search.cgi

Remember to that you can match up two discreet transistors and insert those into the PCB where the LM394 would go according to the diagram below. Just put some thermal compound between them so the temperature equalizes better and then place the TEMCO over those and add a bit more compound.

I'm partway through an order with Futerlec already for some LM394's (I always try to buy at least 1 spare, just in case).

They also have XR2206's at a good price as well as CA3080E's I need for another project. Shame that they've got no 566's in stock, or I would have these as well.

Anyone would think I was stocking up for some more TH designs. Smile

I had already spotted a guy selling 566's for $8.50 a piece, but the postage was horrendous to the UK (over $150 for one chip Shocked

), though admittedly this was for airfreight but still ridiculous.

As luck would have it, I spotted a 566 for sale with a UK vendor on eBay today and picked a single chip up for the grand total of £2.05 (less than $3), they're also checking for me to see if they have any more. Very Happy

My order to Futurlec is also on its way, so that should give me most of the key components for my SN Voice as well as adding some XR2206's to my stock. Add to this the ICL8038 and NE570 I've already got an in my stock of components and I'm likely to be playing with quite a few of Thomas Henry's designs on my bench in the not too distant future.

I've just spotted yet another source of 2k 3500ppm tempco's at Bridechamber's site here:

http://www.bridechamber.com/bridechamber.com/Hard%202%20Find%20ICs.html

They also have a interesting looking front panel available in MOTM format here:

http://www.bridechamber.com/bridechamber.com/SN%20Voice.html

Damn, should have paid more attention to the first post in this thread - panel was already mentioned. Embarassed

As I'm tempted to go down the MOTM format route for my modular systems, this is especially attractive for me. Smile

Board arrived today, looks to be a quality item.

Just need to get my order into Bridechamber now for a tempco, a front panel and some jacks and I'll have everything I need to get this built. I can start stuffing the board with the other bits I've already got this week though.

Thanks for the excellent service.

Regards
