Hi,

I am rebuilding my TA2020 amp, and I would like to add some protection so I bought myself a Velleman K4700.

A lot has been written about the TA2020 from Arjen Helder and about the K4700. But I can't find the end results anywhere, the reason I searched is because I found a thread that mentioned that I needed two K4700 for the TA2020 because it is bridged...??
And there is some discusion about the 1Watt resistors which you place or not place depending it is symmetrical or asymmetrical...??

But again this thread had no end result.

I hoped that someone knows the answer or has this configuration. Or maybe has a spare of the protection board Arjen Helder made for this amp.
