Dont worry about the  quantity running low or out. I will make more.

 Ready to use module replaces the Kenwood   TA100w    in the KA-8300/ KA-9800  KA-7500

The TA100WA+  for the KA-9100/9150 KA-770D is ready and listed separately.   

The TA100W and TA-100WA  are very  similar but  do not run at the right temperature if swapped.  

Repairable discrete design.    Carefully designed to fit the same mounting holes, no drilling or grinding necessary.

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

Higher current gain   8,000-20,000 vs original 2500.

Higher heat transfer   Theta 1.5  vs 1.8

These same power transistors are used in the 140 watt per channel  Marantz SR8012  and the Yamaha RX-A2070

 NEW  not 40 years old or counterfeit. Sanken made the TA-100W for the KA-8300/KA-9800  that Kenwood introduced in in 1975.
