Awaiting delivery
Tea-bag,
I am still awaiting delivery of the boards and bits for this group buy. Am I being impatient or should the package have been delivered to me in Aus already?

Update: package arrived in today's mail. This confirms that I was impatient!
Thanks Tea-bag for the service.
Just wondering which R<number> these resistors belong to in Salas' design; I can't seem to make sense of it 🙂 thanks in advance

The 6.754K 25ppm is for R5 and then you skip R6 in parallel. Its a special custom value to avoid producing it through parallelism. So you solder it for R5 and you use no R6.
The 47k resistors for R14s,best quality resistor you have here, your second best for R1s i think. Someone please correct me if i`m wrong.

Ah OK 🙂 Thank you!
So I have an Audio Technica AT440MLa Dual-MM cartridge. It has a recommended load impedance of 47kOhm, and outputs in the range 4.0 (mV, 1 kHz, 5 cm/sec). Based on this, I have the following values:
- R2 - 91 Ohm
- R3 - Do not use
- R4 - 1.8 kOhm
- R5 - 6.754 kOhm
- R6 - Do not use
- R13 - 5.6 kOhm
Is my interpretation of the guide correct for my chosen cartridge? Also, I am opting not to install R1x - R4x as I won't be changing the input impedance for a while (at least until I have a new cartridge). Will this work?
Correct
*graemed from Canberra very recently built what looks like the same configuration you seek and he has Audio Technica 150MLX 4mV MM. He reported they worked fine together in the phono thread and has posted a few photos. They show no R1x-R4x or DIP switch also. Using R1 only for fixed loading certainly works. Maybe you can ask him for details there. http://www.diyaudio.com/forums/analogue-source/129126-simplistic-njfet-riaa-1644.html#post4807630

I guess I missed the group buy on this? Tea Bags's signature has a spot for boards, but it seems to be dead, no links. Will there be another group buy? Or, could I possibly get the copy of the artwork to have some boards made? Thanks, Andy
Hi guys,
Yes I’ve missed the boat too!
Is there any chance of another one (Group buy I mean) coming along in the not too distant future?
Kind regards
Royville,

Royville,
There will be another GB. I will put both you down on the spreadsheet.
Hi Tea-Bag,
Thats great news thanks.
Whats the best way to know when a new GB is starting? Shall I just keep watching this thread?
Thanks Roy.

Yes, but I also send private messages to those who have signed up. Giving further instructions.
