Equalization circuit boards

for all Studer A80 and B62

To change the speed or equalization, you always need two circuit boards for recording and two circuit boards for playback. If you "only" want to carry out a repair, the circuit boards should be replaced in pairs. So 2 times recording or twice playback.

As with the Studer A101 hybrid amplifier module, SMD technology is clearly an advantage.

The following equalizations are available for playback:

CCIR 19 cm / s and 38 cm / s 1,080,921

NAB  19 cm / s and 38 cm / s 1,080,923

CCIR 9.5 cm / s and 19 cm / s 1.080.925

CCIR 38 cm / s and 76 cm / s 1,080,927

NAB  38 cm / s and 76 cm / s 1,080,929

NAB  38 cm / s and 76 cm / s 1,081,881

NAB  38 cm / s and 76 cm / s 1,081,882

The coding of the original Studer equalization boards was done with a pressed pin. We will only leave the appropriate opening blank and cover the other opening in color (red for the recording and green for the playback equalization). The circuit boards are too small to label the type of equalization and its speed.

We want to offer various and especially useful repair kits for the Studer A80 or B62. These include the complete relay set for the audio area, replacement kits for the recording and playback boards, repair kits for the audio cards or the drive control. Many of these replacement parts are specially made for us or by us, see ITT replacement relays, the best replacement for the hybrid amplifier A101 or the excellent EQ boards.
