Modules
S-100+
Replaces the S-100, S-80, SS-120A
This module is listed for individual sale. A good upgrade is to buy two.
This ready to use module replaces the SS-120A in the Sony STR-6800SD or the S-100 in the Optonica SM-4646, even the S-80 used in the LR-5555A, SM-3636, Nikko NR-815, and AS-1080DB. Carefully designed to fit the same mounting holes, no drilling or grinding necessary. Very fast and easy install in the Sony. Built with modern output transistors and discrete, repairable design.
| Higher current: | 15 amp vs 10 |
| Higher voltage: | 160 volt Vce vs 120 |
| Higher dissipation: | 160 watt vs 100 |
