Sennheiser SK100 G4 C-Band

Many years ago I bought several Sennheiser systems, and with the passage of time the transmitters have been damaged, normally. The problem is that the C and B bands of my transmitters were not available in the places I used to buy. It was great to be able to buy from Thomann, because there are all the bands I need, at a very competitive price (in my country they cost up to triple) and they arrived in perfect condition and very quickly ... extremely happy with the purchase. Now, little by little I can change the transmitters, so that they are in perfect condition.
