This kit addresses the common components most likely to degrade. Eleven components are for the amplifier panel and two v. 2-400 to four (4.1) are for the control pod. My source for the nylon standoffs (circuit board spacers) changed, so the replacement standoffs mount differently.
Included with the speaker surround kit are instructions. A new Zener diode is mounted above the board to stay cooler.Three 3-watt resistors replace lower wattage originals. Two new ICs with 8-pin sockets for 4.1 version, but not needed for v. 2-400 version and new main and rear/surround volume control potentiometers are for the preamplifier volume control pod. Rubber Speaker Surrounds: This is a good time to remove the grills from the subwoofer's 6.5 speakers to check their condition.
The foam surrounds degrade after 10-20 years. They become weak, and eventually crumble.
Two rubber surrounds will be included with the repaired amplifier. I will include a small bottle of rubberized speaker glue.
I install the parts kit and send back with the amplifier and the control pod a refoam kit for your two original speakers.
