### DESCRIPTION

Universal crossover board for Radiotehnika S-30/S-30B speakers (S-30A has no crossover).

In both types of speakers resistors and coils have to be taken from the stock boards, but new film capacitors have to be used.


### TECHNICAL DETAILS / COMPONENTS

Board size: 90x82 mm

Film capacitors have to be equal or less 5 mm in width and have 15 mm lead spacing. All capacitors are 1 uF 100 V.

Variable resistor CP5-28B 33 Ohm 1 W.

1x 100 Ohm 2 W resistor.

For S-30: 3x 22 Ohm 2 W resistors.

For S-30B: 4x 12 Ohm 2 W resistors.


### LEARN / TOPIC / BUILD INSTRUCTIONS

"0" marking under resistors means that you have to put jumper instead of the resistor (you can use leads cut from new resistors that you've installed).

"-"  marking under resistors means that no part should be placed in that place.

Coil pinout is the same as in official S-30 or S-30B schematics.
