New plug-in equalization PCBs for all Studer A80 tape machines. Of course in the usual high revox-online quality. We did not copy the not so successful original circuit board 1: 1, we also use the better SMD technology here. The conductor routing is better and there are no wired components that have to be soldered by hand. We at revox-online offer all equalization for the recording and playback of the Studer A80 or B62 from 1,080,920 to 1,080,929 and 1,081,880 to 1,081,882
