We are obviously late with this project, so I owe apologies to all. Iíve had to make some changes in PCB design, minor changes in fact, but they meant another round of process. Now I did drew the line, so complete PCB series should be done in about two weeks. Holidays will be over then, which*might complicate things with building, but then again delivery will be probably easier.

Apart from some layout (and layout related) changes, there are two parts changes with respect to the preliminary documents that you received. The first, as some of you noticed, BF245 is obsolete and practically already unavailable, and hence it is abandoned in this project. Just until a few weeks ago Iíve had my own stock, and I was unaware of how quickly it disappeared from major electronics parts stores. In fact, things with JFETs in classic leaded TO-92 package generally got tricky, as industry moved to SOT-23. This is great for automatic assembling, but troublesome for many DIY-ers, so I rather choose to stick with J113 here. The second is I2S / simultaneous mode switch, which is changed to more classic style DIP switch.

Speaking on partsÖ Their availability, possible substitutes etc. might be a huge topic, and I will set another page that will be dedicated to anything related to parts.

According to Pedja, almost all unpopulated PCBs, and unpopulated PCBs with toroidal transformers have been shipped, and the plan is to start sending out unpopulated PCBs*with EI transformers tomorrow. It will take some more days for the complete kits.

Don't want to open a build thread as help will be provided by Audial. I am sourcing the parts and have a question about PS transformers.

Do I have to buy transformers with secondaries marked 9V (which mean they measure with the voltmeter : 9x1.41 (less for a R-core) ?

In the same spirit do you believe the - 16 V shunt could support a 18 V transformer ?

Thank you in advance...
