George,

I sent the payment, please check your e-mail, as I think that paypal omitted one line of my address.

Best Regards,

Davide

P.S. Great job !

I got it. The email that I received from Paypal is complete and in English. I don't know what happened to yours. The boards will go out tomorrow morning.

It would be nice if the more general threads that are of wide interest could stay in the general tubes forum. Things like the discussions of your experiments, how much power can you extract from a pari of 6L6's, that kind of thing, are of great general interest and will get more views and discussion in the general forum.

Even a lot of the discussion of your development process for products, which you will end up supporting in this forum, interests a lot of people who probably have a lesser interest in the end product.

I don't plan on moving any of the "experiments" or development threads here. I have forwarded the lists of threads posted above to the forum operators. I looked through each one to make sure that it deals with the Simple SE, the Tubelab SE, or the Simple P-P. This forum will be the place to look for assistance or discussion of the boards that I sell. I am trying to get all of the board related threads in one place so that they can be easilly found by someone with a question.

The existing and future experiments will remain in the Tubes / Valves forum where they belong. Those that lead to the development of a worthwhile idea, concept or circuit may get documented on my web site as well. If one of those ideas gets developed into a new PC board, the original thread will still remain in its original place. A new thread will start here when it becomes a product.

I am adding my list here so that everything is in one place. I believe these lists cover most of the Tubelab related threads. I am emailing a link to this thread to the forum operators tomorrow. They will move the threads here and leave a note directing people to their new location.

George,

The boards arrived, thank you very much ! I have some of questions:

1) For the simpleSe, my transformer does not have a 6.3V 5A secondary, but two 6.3V 3A. Can I connect them in parallel in the board socket ?

2) I saw in the schematic of the PSU of the SimpleSE that you do something that I would like to understand, connecting the B+ to the heater. What's the theory behind that ?

3) Did I understand correctly that the SimpleSE uses hybrid rectification ? What are the advantages and disadvantages of this approach ?

4) Why not using different rectifiers to tune the voltage ? I saw you can change it of 50V, this can be useful for the tubelabSE to run the 45 a bit cooler.


Thanks,

Davide

You may want to start a separate thread specific to your questions.
