Don't worry Torpedo. :) The spreadsheet it's ok for me. I want 2 Sigma 22 with his components and 4 Dynafet transistors sets. -- o -- Rodrigo

I'm not sure, but I think the spanish gang will use the same output voltage as the rest of the group. Is it possible to use Nuvotem Talema transformers in the S22?, because they are very easy to us get it in Spain and they have a good price. This is the datasheet of the 2x30v 225VA. Are Piltron or SumR transformers a better choice than Nuvotem? Sorry for repeating the question, but for me it is very important to know if we can use these transformers. -- o -- Rodrigo

I could not talk to them, it's only my opinion. These days were public holidays in Spain (carnivals) and I have been away from home. OK, thank you very much. I'm very busy with my work and I haven't thought about how to configure the I/O of my Dynafet. -- o -- Rodrigo

I don't want Sowters at this moment. -- o -- Rodrigo

I think it's a good option too, I haven't any problems to mount this controller boards. -- o -- Rodrigo

Hi guys Since my friend Torpedo spoke to me of the existence of this group, I have followed with great interest everything that happens here. I have always liked the designs of Kevin and I see that you are working hard on a proyect with a high-level desing. There are people with very good ideas in this group, but I think we should go step by step for doesn't confuse the non-DIY members. I think we should know the approximate price of a basic configuration of Dynafet with 2 ch and 4 ch to determine how many units are to be built, if a user wants more quality components, or a more complicated desing (microcontroller, I2C-bus, input transformers, etc)... he already know that have to pay more. Like we live in Spain (Torpedo, Hitoridekimasu, and me), it's likely to be interesting to us buy directly the "heavy" materials (boxes, toroidal transformers), because the dispatch from US may be more expensive than the money that we can save buying with the group. We will not have any problem to make the machining of the boxes. I don't have many problems to understand your comments in english, but for me it's difficult to write in this language , and the google "translator/language destroyer tool" doesn't help much :) -- o -- Rodrigo
