Dear Mr. Szabolcs,
I see and I would to buy your pantograph servo decoder.
I have a nano servo with a maximum power tension of 4,2v.
If applied more than 4,2v to the servo, the servo could be destroyed!!
I saw on the decoder pictures, that your decoder have a tension regulator (LM78XX)
Can you tell me the value of this regulator? It will be possible to install a tension regulator that provide a 4.0v?
